An atom has 35 protons, 42 neutrons, and 33 electrons. What is the atomic number?
Answers
The atomic number of arsenic (As), which possesses 35 protons, 42 neutrons, and 33 electrons, is 33.
Why is atom called and how it is formed?However, we must travel back to 400 B.C. ancient Greece to understand the word "atom." Democritus, a renowned philosopher, recommended the use of the Greek word atomos, which means uncuttable. So, he said, all matter could someday be reduced to discrete, tiny particles, or atomos. Any subatomic particle of matter that has at least one proton is considered to be an atom. The atoms include, for instance, hydrogen (H) and neon (Ne).
Atoms are made up of a nucleus in the middle that is surrounded by protons, neutrons, and electrons. During the fission process, uranium is broken up into smaller atoms, producing new atoms. The creation of atoms in enormous numbers can be seen in the Big Bang and Supernova phenomena.
Who created atom and who defined it?Up until the 1800s, this notion of tiny, inseparable pieces of matter remained. The contemporary atomic idea was initially started by the eminent chemist John Dalton (1766–1844). Around 400 B.C., a renowned philosopher by the name of Democritus proposed the Greek word atomos, which implies uncuttable. In the end, all matter could be reduced to distinct, tiny particles, or atomos, he said. This Greek term is where the word "atom" originated.

Answers
Answer:
It can use a small amount of sunlight for photosynthesis
Explanation:
Seaweeds are a group of marine plants/algae that grow attached to rocks underwater. However, despite their depth underwater, they still perform photosynthesis, which is a process that requires energy from sunlight.
Seaweeds are able to perform photosynthesis underwater because they are efficient users of sunlight energy. Hence, they require only a small amount of sunlight that penetrates the ocean to perform photosynthesis.

1)Calculate the pH of a 0. 03 M solution of nitric acid.
2)Calculate the hydronium ion concentration of a sulfuric acid solution with a pH of 5. 43.
3)Calculate the pOH of a 0. 025 M solution of sodium hydroxide.
4)Calculate the pH of a 0. 002 M solution of lithium hydroxide
Answers
pH = -log[H+]
where [H+] is the concentration of hydronium ions in the solution.
Since nitric acid is a strong acid, it completely dissociates in water to form H+ ions and NO3- ions. Therefore, the concentration of H+ ions in a 0.03 M solution of nitric acid is also 0.03 M.
Substituting this value into the formula, we get:
pH = -log(0.03) ≈ 1.52
Therefore, the pH of a 0.03 M solution of nitric acid is approximately 1.52.
2) The hydronium ion concentration of a sulfuric acid solution with a pH of 5.43 can be calculated using the formula:
pH = -log[H+]
where [H+] is the concentration of hydronium ions in the solution.
Substituting the given pH value into the formula, we get:
5.43 = -log[H+]
Taking the antilogarithm of both sides, we get:
[H+] = 10^(-5.43)
[H+] ≈ 2.15 x 10^(-6) M
Therefore, the hydronium ion concentration of the sulfuric acid solution is approximately 2.15 x 10^(-6) M.
3) The pOH of a 0.025 M solution of sodium hydroxide can be calculated using the formula:
pOH = -log[OH-]
where [OH-] is the concentration of hydroxide ions in the solution.
Since sodium hydroxide is a strong base, it completely dissociates in water to form Na+ ions and OH- ions. Therefore, the concentration of OH- ions in a 0.025 M solution of sodium hydroxide is also 0.025 M.
Substituting this value into the formula, we get:
pOH = -log(0.025) ≈ 1.60
Since pH + pOH = 14, we can calculate the pH of the solution as:
pH = 14 - pOH = 14 - 1.60 ≈ 12.40
Therefore, the pH of a 0.025 M solution of sodium hydroxide is approximately 12.40.
4) The pH of a 0.002 M solution of lithium hydroxide can be calculated using the formula:
pH = 14 - pOH
where pOH is the negative logarithm of the hydroxide ion concentration [OH-].
Since lithium hydroxide is a strong base, it completely dissociates in water to form Li+ ions and OH- ions. Therefore, the concentration of OH- ions in a 0.002 M solution of lithium hydroxide is also 0.002 M.
Substituting this value into the formula, we get:
pOH = -log(0.002) ≈ 2.70
Therefore, the pH of a 0.002 M solution of lithium hydroxide is approximately:
pH = 14 - pOH = 14 - 2.70 ≈ 11.30

The principle of option D. Uniformitarianism states that the physical, chemical, and biological processes at work shaping the Earth today have also operated in the
Option D. Uniformitarianism is the principle stating that the physical, chemical, and biological processes at work shaping the Earth today have also operated in the geologic past. It is based on the idea that the present is the key to the past. In other words, the same natural laws that operate in the universe today have been operating since the beginning of time.
James Hutton was the first to propose this principle in the late 18th century. He suggested that the Earth was shaped by slow-acting geological forces such as erosion, sedimentation, and uplift over long periods of time. He believed that the same processes were still happening today and that they had operated in the past.
This principle is an important concept in geology because it allows scientists to interpret the Earth's history based on the processes that they observe today. By understanding how these processes work and how they have changed over time, scientists can reconstruct the history of the Earth and its environments.
Uniformitarianism has been tested and proven through many observations and experiments. For example, the study of sedimentary rocks has shown that they were formed in the past through the same processes that are observed today, such as deposition of sediment by water, wind, or ice.
Similarly, the study of volcanoes has shown that they are formed by the same processes as today, such as the movement of magma from deep within the Earth.
In conclusion, Uniformitarianism is the principle that allows us to interpret the Earth's history by observing the processes that shape it today. It is a fundamental concept in geology and has been tested and proven through many observations and experiments.

Matter or energy can change from one form to the other.
The law agrees with the Biblical account of Creation
(more than one answer)
Answers
Answer:
Matter or energy can change from one form to the other
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed but can only be transformed i.e. changed from one form to another. For example, mechanical energy can be changed to electrical energy.
Likewise, the law of conservation of mass/matter states that matter can not be destroyed or created but can change via physical or chemical means to conserve it. For example, matter can change from liquid state to gaseous state.
From the above two laws, it can be said that "matter or energy can change from one form to the other".
What mass of iodine, I2 (molar mass 253.80 g/mol), must be used to prepare a 0.960 m solution if 100.0 g of ethanol, C2H5OH, is used
Answers
Approximately 551.63 grams of iodine (I2) must be used to prepare a 0.960 molar solution using 100.0 grams of ethanol (C2H5OH).
To determine the mass of iodine (I2) required to prepare a 0.960 molar solution using 100.0 g of ethanol (C2H5OH), we need to first calculate the number of moles of ethanol and then use the stoichiometry to determine the corresponding moles of iodine.
Step 1: Calculate the moles of ethanol (C2H5OH):
Molar mass of ethanol (C2H5OH) = 12.01 g/mol (C) + 2 * 1.01 g/mol (H) + 16.00 g/mol (O) = 46.07 g/mol
Moles of ethanol = Mass of ethanol / Molar mass of ethanol
= 100.0 g / 46.07 g/mol
≈ 2.17 mol
Step 2: Use the stoichiometry to determine the moles of iodine (I2):
From the balanced chemical equation for the preparation of the solution, we need a 1:1 mole ratio between ethanol and iodine.
Therefore, the moles of iodine = Moles of ethanol = 2.17 mol
Step 3: Calculate the mass of iodine:
Mass of iodine = Moles of iodine * Molar mass of iodine
= 2.17 mol * 253.80 g/mol
≈ 551.63 g
It's important to note that the molarity (M) of a solution is defined as the number of moles of solute per liter of solution. In this case, the molarity is given as 0.960 M, indicating 0.960 moles of solute per liter of solution.

In the formation of carbon dioxide from carbon monoxide and oxygen, how many moles of carbon monoxide are needed to react completely with 7.0 moles of oxygen gas
Answers
To react completely with 7.0 moles of oxygen gas, 14.0 moles of carbon monoxide are needed.
The balanced chemical equation for the formation of carbon (CO2) from carbon monoxide (CO) and oxygen (O2) is:
2CO + O2 → 2CO2
From the equation, we can see that it takes 2 moles of CO to react with 1 mole of O2 to produce 2 moles of CO2.
Given that we have 7.0 moles of O2, we can determine the amount of CO required by using the stoichiometric ratio:
(2 moles CO / 1 mole O2) × 7.0 moles O2 = 14.0 moles CO
Therefore, 14.0 moles of carbon monoxide are needed to react completely with 7.0 moles of oxygen gas.

How many liters of C2H2 are required to produce 8 L of CO2 assuming the reaction is at STP?
Answers
Approximately 3.72 liters of C2H2 are required to produce 8 L of CO2 at STP.
We can use stoichiometry to determine the amount of C2H2 required to produce 8 L of CO2 at STP.
According to the balanced equation, 2 moles of C2H2 react with 5 moles of O2 to produce 4 moles of CO2 and 2 moles of H2O. This means that the ratio of C2H2 to CO2 is 2:4 or 1:2.
At STP, 1 mole of any gas occupies 22.4 L. Therefore, 8 L of CO2 corresponds to 8/22.4 ≈ 0.357 moles of CO2.
Since the ratio of C2H2 to CO2 is 1:2, we need half as many moles of C2H2 as moles of CO2:
0.357 moles of CO2 × (1 mole of C2H2 / 2 moles of CO2) = 0.179 moles of C2H2
Now we can use the ideal gas law to convert moles of C2H2 to liters at STP:
PV = nRT
where P is the pressure (1 atm), V is the volume (unknown), n is the number of moles (0.179 moles), R is the gas constant (0.0821 L·atm/K·mol), and T is the temperature in Kelvin (273 K at STP).
Solving for V, we get:
V = nRT/P = (0.179 mol)(0.0821 L·atm/K·mol)(273 K)/(1 atm) ≈ 3.72 L

A coffee cup calorimeter consists of a coffee cup, a thermometer, water, and a reactant placed inside the cup. Unlike a bomb calorimeter, a coffee cup calorimeter is a constant pressure calorimeter.
calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature. When an endothermic reaction occurs, the heat required is absorbed from the thermal energy of the solution, which decreases its temperature . The temperature change, along with the specific heat and mass of the solution, can then be used to calculate the amount of heat involved in either case.

Ethanols cells are fuel cells that generate electric power by converting ethanol (C2H5OH) and oxygen (O2) into carbon dioxide (CO2) and water (H2O).Ethanol (C2H5OH) is a colorless, flammable liquid. It is used in a variety of applications, including food, medical, and fuel. Ethanol has a high energy density, which makes it an ideal fuel for fuel cells. The use of ethanol in fuel cells is a significant breakthrough in renewable energy technology. Ethanol is a renewable energy source that is derived from biomass.
Ethanol can be produced from a variety of sources, including sugar cane, corn, and other plants. The use of ethanol as a fuel source is environmentally friendly and has a minimal impact on the environment. The working principle of ethanol cells is similar to that of other fuel cells. The electrochemical reaction takes place in the presence of a catalyst. In an ethanol cell, ethanol is oxidized at the anode, producing carbon dioxide, water, and electrons. At the cathode, oxygen is reduced, producing water and accepting electrons. The overall reaction is: C2H5OH + 3O2 → 2CO2 + 3H2O The feasibility of ethanol cells depends on a variety of factors, including the availability of ethanol, the cost of production, and the efficiency of the cell. Ethanol cells have a long life span and are relatively low maintenance. The economics of ethanol cells is dependent on the cost of production and the market demand.

When calibrating a colorimeter, it is important to use a blank solution that will not interfere with the measurement and is expected to have negligible absorbance in the wavelength range of interest. Among the answer choices provided, de-ionized water would be the most appropriate option to use as the blank solution.
Tap water may contain impurities that could affect the absorbance readings, making it unsuitable for calibration purposes. The undiluted dye solution would likely have a high absorbance value, which would not be suitable for setting the reading at 0 absorbance. Ethanol, depending on its concentration and any impurities, may also have some absorbance in the wavelength range of interest, making it less ideal as a blank solution.
De-ionized water is commonly used as a blank because it is free of ions and impurities that could interfere with the measurement. It typically has negligible absorbance in most wavelength ranges, allowing it to be used as a baseline reference for setting the reading at 100% transmittance or 0 absorbance

The solubility of mercury(II) iodide (HgI₂) in pure water is determined by its Ksp value, which is 2.9 x 10⁻²⁹.
In a 3.0 M solution of NaI, assuming (HgI₄)₂₋is the only significant species, the solubility of HgI₂can be calculated using the Ksp and K values.
What are the solubility values of HgI₂in pure water and a 3.0 M solution of NaI?The solubility of HgI2 in pure water can be calculated using its solubility product constant (Ksp). The Ksp value for HgI₂ is given as 2.9 x 10⁻²⁹. Solubility product constant represents the equilibrium constant for the dissolution of a sparingly soluble salt. By solving the equilibrium expression for HgI₂, we can determine its solubility in pure water.
In a 3.0 M solution of NaI, assuming the formation of (HgI₄)₂₋ is the only significant Hg-containing species, the solubility of HgI2 can be calculated using the Ksp and K values. The K value given for(HgI₄)₂₋ - is 6.8 x 10²⁹. By setting up an equilibrium expression considering the dissociation of HgI₂ into (HgI₄)₂₋ ions, we can determine the solubility of HgI₂in the presence of the NaI solution.
These calculations involve using the principles of equilibrium and the relationship between concentrations of dissolved species and their equilibrium constants.

(a) No, ammonium nitrate aerosol will not form in the system if E NH₃ < 2E SO₂ because there is insufficient ammonia relative to sulfur dioxide emissions for the formation of ammonium nitrate.
(b) The formation of NH₄NO₃ aerosol is limited by the supply of NH₃ (ammonia) in the system, rather than the supply of NOₓ (nitrogen oxides).
(c) Decreasing SO₂ emissions would cause a decrease in total aerosol mass concentrations because the reduced emissions of sulfur dioxide result in a lower availability of sulfate ions, which are necessary for the formation of ammonium sulfate and other sulfate-based aerosols.
(a) Ammonium nitrate (NH₄NO₃) aerosol will not form in the system if the emissions satisfy the condition E NH₃ < 2E SO₂. This is because there is an insufficient amount of ammonia (NH₃) relative to sulfur dioxide (SO₂) emissions to form ammonium nitrate through chemical reactions.
(b) If 2E SO₂ + E NOₓ > E NH₃ > 2E SO₂, the formation of NH₄NO₃ aerosol is limited by the supply of NOₓ (nitrogen oxides) rather than the supply of ammonia (NH₃). The excess nitrogen oxides available in the system compared to ammonia allow for the formation of ammonium nitrate aerosol.
(c) Under the conditions of (b), decreasing SO₂ emissions would cause an increase in total aerosol mass concentrations. This is because the reduced emissions of sulfur dioxide result in a lower availability of sulfate (SO₄) ions, which are essential for the formation of ammonium sulfate ((NH₄)₂SO₄) and other sulfate-based aerosols. As a result, more ammonia and nitrogen oxides would be available for the formation of ammonium nitrate aerosol, leading to an increase in the total aerosol mass concentrations.
