consider the following equilibrium mixture in a closed system: h2o(g) co(g) h2(g) co2(g). explain what would happen to the equilibrium upon the addition of steam?
Answers
When steam (H₂O(g)) is added to the equilibrium mixture of H₂O(g), CO(g), H₂(g), and CO₂(g), it will affect the position of the equilibrium.
The reaction between CO and H₂ to form CO₂ and H₂O is exothermic, meaning that it releases heat, and is described by the following equation:
CO(g) + H₂(g) ⇔ CO₂(g) + H₂O(g)
When steam is added to the system, it will increase the concentration of H₂O(g), which acts as a reactant in the forward reaction and a product in the reverse reaction. This will shift the equilibrium towards the reactants (CO(g) and H₂(g)) to maintain a constant concentration of products. The addition of steam will decrease the concentration of CO₂(g) and H₂(g) and increase the concentration of CO(g) and H₂O(g).
This shift in the equilibrium position will cause the reaction to be more favorable towards the formation of CO and H₂O, which are the products of the reaction, rather than CO₂ and H₂, which are the reactants. This is because the equilibrium constant for the reaction (Kc) is proportional to the product of the concentrations of the products over the product of the concentrations of the reactants.

When baking soda and vinegar react bubbles are produced. What mostly occurred?
Answers
Answer:
a chemical reaction
Explanation:
Answer:
When vinegar comes in contact with baking soda, a cascade of two chemical reactions takes place. The result is carbon dioxide gas—a product of the reactions—bubbling up in a water solution. The bubbles create the fizz and sizzling sound.Baking soda is bicarbonate (NaHCO3) and vinegar is acetic acid (HCH3COO). One of the products this reaction creates is carbon dioxide, which makes the bubbles. When the baking soda meets the vinegar, there is a chemical reaction as carbon dioxide gas is created and fills the balloon causing it to inflate.

a reaction of 22.85 g of sodium hydroxide with 20.82 g of hydrogen chloride produces 10.29 g of water and X g of sodium chloride.
X = ____ g
Answers
The mass of 22.85 g of sodium hydroxide with 20.82 g of hydrogen chloride produces 10.29 g of water and X g of sodium chloride is 33.389 g.
To find the mass of Sodium Chloride, NaCl, we must write the reaction between sodium hydroxide and hydrogen chloride. The balanced chemical equation. NaOH + HCl → NaCl + H₂O
The molar mass of NaOH = 23 + 16 + 1 = 40 g/molThe molar mass of HCl = 1 + 35.5 = 36.5 g/molUsing the balanced chemical equation and the Law of Conservation of Mass, we can write the equation:
Number of moles of NaOH used = Number of moles of HCl usedNumber of moles of NaCl formed = Number of moles of HCl usedMass of NaOH = 22.85 g
Molar mass of NaOH = 40 g/molNumber of moles of NaOH used = 22.85 g ÷ 40 g/mol = 0.57125 molMass of HCl = 20.82 g
Molar mass of HCl = 36.5 g/molNumber of moles of HCl used = 20.82 g ÷ 36.5 g/mol = 0.57041 molFrom the balanced equation:
Number of moles of NaCl formed = Number of moles of HCl used = 0.57041 mol
Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol
Mass of NaCl formed = Number of moles of NaCl formed × Molar mass of NaCl
= 0.57041 mol × 58.5 g/mol
= 33.389 g
Therefore, the mass of sodium chloride, NaCl, formed is 33.389 g.

Answers
A star evolves off the main sequence when helium is exhausted in the stellar core.Our solar system’s gas giant planets (and those of other solar systems) did not become stars because they are not massive enough to generate the high temperatures and pressures necessary to start hydrogen fusion in the core.
Stars evolve off the main sequence when the nuclear fusion in their cores is no longer capable of supplying sufficient energy to maintain the gravitational energy, causing it to contract and the outer layers to expand and cool. When hydrogen runs out in the core of a star, the core shrinks and heats up and the outer layers expand, resulting in a red giant. However, when helium is consumed in the core, the core collapses and heats up, causing the outer envelope to get expelled, and the core evolves into a white dwarf.
A gas giant planet's temperature and pressure aren't high enough to generate fusion. They aren't dense enough to generate the heat required for nuclear fusion. Therefore, gas giant planets do not generate their own light and heat in the same way as stars. They can emit more energy than they obtain from the sun if they have a significant atmosphere. The planets in the solar system, such as Jupiter and Saturn, are examples of gas giants.

what’s the suppose when you boil water and use it to cook pasta. What do you think happens to the total mass of the pasta and the water as the pasta cooks?
Answers
The pasta gains mass and the water loses mass as the pasta cooks in boiling water.
When you boil water and use it to cook pasta, the water absorbs heat and energy, causing its temperature to increase. As a result, the water molecules gain kinetic energy and begin to move more rapidly, which causes them to collide with each other and transfer this energy to the pasta.
As the pasta cooks, it absorbs water and expands in size. Some of the starches in the pasta are released into the water, which causes the water to become thick and starchy. The pasta also loses some of its starch content and becomes softer and more edible.
The total mass of the pasta and water together remains the same throughout the cooking process, as no matter is created or destroyed. However, the pasta gains mass as it absorbs water, while the water loses mass as it evaporates into the air during the boiling process.
Therefore, the pasta gains mass and the water loses mass as the pasta cooks in boiling water.

Answers
The steady-state approximation states that the rate of formation of A* equals the rate of destruction, with termolecular reactions being third order and bimolecular reactions being first order. The rate of reaction is proportional to the concentration of reactants, with higher pressures causing a higher rate law.
The steady-state approximation states that the rate of formation of A* equals the rate of destruction, with the rate of reaction being k1[A][M] minus the rate of reverse reaction k-1[A*][M]. The rate of reaction for termolecular reactions is third order, while for bimolecular reactions, it is first order.
a) The steady-state approximation states that the rate of formation of A* is equal to the rate of destruction, which is the same as the rate of reaction k1[A][M] minus the rate of reverse reaction k-1[A*][M].
The steady-state concentration of A* is [A*]= k1[A][M]/k-1[A*][M].A(g) + M(g)
yields k1 on the top and k-1 on the bottom A*(g) + M(g)A*(g) yields k2 on the top B(g)As per the problem, we know that CH3NC* leads to CH3CN(g) through the reaction: A*(g) yields k2 on the top B(g)We can calculate the rate of reaction for this process as follows: rate of reaction= delta[B]/delta t= k2[A*]
b) The rate of reaction for a termolecular reaction is proportional to the square of the concentration of reactants, which means that it is third order in general. If the pressure of the gas is increased, the overall rate law becomes: third order.
c) The rate of reaction for a bimolecular reaction is proportional to the concentration of reactants, which means that it is first order in general. If the pressure of the gas is decreased, the overall rate law becomes: first order.

If you need to produce 66 grams of carbon dioxide, how many liters of water vapor would you produce as a by product?
Answers
The question requires us to calculate the amount of vapor water produced as a by-product when 66g of carbon dioxide are obtained from the combustion of propane.
Considering the combustion of propane (C3H8), we have the following reaction:
\(2C_3H_8+9O_2\to4CO_2+2CO_{}+8H_2O_{(v)}\)IFrom the reaction, we can see that the stoichiometric relationship between C3H8 and water (H2O) is as follows:
2 mol C3H8 ---------- 8 mol H2O
Then, to calculate the amount of water produced as a by-product, we'll need to determine the amount of reactant needed to produce 66g of CO2.
Since the molar mass of CO2 is 44g/mol and considering the reaction written above, we can write:
2 mol C3H8 ---------- 4 mol CO2
x ---------- (66g/44g) = 1.5 mol CO2
Solving for x, we have that 0.75 mol of C3H8 are required to produce 66g of CO2.
Now, we calculate the amount of water that should be obtained from 0.75 mol of C3H8:
2 mol C3H8 ---------- 8 mol H2O
0.75 mol C3H8 ----- y
Solving for y, we have that 3 moles of water will be obtained as a by-product.
At last, we convert the calculated amount of vapor water into its volume considering the Standard Temperature and Pressure conditions (STP), where 1 mol of a gas corresponds to 22.4 L of the same gas:
1 mol vapor H2O ---------- 22.4 L vapor H2O
3 mol vapor H2O --------- z
Solving for z, we have that 67.2 L of vapor water will be obtained as a by-product when 66g of CO2 are produced from the combustion of propane.

how long must current of 5 a be applied to a solution containing ag to produce 10.5 g of silver metal? (2 pt)
Answers
The time required for a current of 5 A to produce 10.5 g of silver metal is 1822.8 seconds or approximately 30.38 minutes.
The amount of silver deposited can be calculated using Faraday's law of electrolysis, which states that:
mass of metal deposited = (current × time × atomic mass of metal) / (charge per mole of electrons)
The atomic mass of silver is 107.87 g/mol, and the charge per mole of electrons is the Faraday constant, which is 96,485 C/mol.
Substituting the given values, we get:
10.5 g = (5 A × time × 107.87 g/mol) / (96485 C/mol)
Solving for time, we get:
time = (10.5 g × 96485 C/mol) / (5 A × 107.87 g/mol) = 1822.8 s
Therefore, the time required for a current of 5 A to produce 10.5 g of silver metal is 1822.8 seconds or approximately 30.38 minutes.

explain the difference between a mixture of a element and a compound made of elements. Write about atom in your answer
Answers
Answer:
A mixture of an element and a compound made of elements are two different types of combinations of matter.
An element is a substance that cannot be broken down into simpler substances by chemical means. Atoms are the smallest units of elements that still retain their properties. For example, gold is an element with the symbol Au, and its atoms cannot be broken down into simpler substances without losing their properties.
A compound, on the other hand, is a substance made up of two or more different elements chemically combined in a fixed ratio. For example, water is a compound made up of two hydrogen atoms and one oxygen atom, with the chemical formula H2O.
A mixture of an element and a compound is a combination of two or more substances that are physically mixed together, but not chemically combined. The substances in the mixture retain their individual properties and can be separated by physical means, such as filtering or evaporation. For example, a mixture of salt (a compound) and iron filings (an element) can be physically separated by using a magnet to attract the iron filings, leaving the salt behind.
In summary, the difference between a mixture of an element and a compound made of elements is that the former is a physical combination of two or more substances that retain their individual properties, while the latter is a chemical combination of two or more elements in a fixed ratio that results in a new substance with its own distinct properties.
