what is the balanced equation for calcium sulfate?​

The partial pressure of hydrogen is 0.98 atm while the partial pressure of water is 0.02 atm. The total pressure of the system is 1 atm.

We have seen the reaction as it has been shown in the equation that is attached to the question above. Now, we must have to find the number of moles of the hydrogen that was obtained.

Number of moles of sodium =  1.90 g/23 g/mol = 0.08 moles

2 moles of sodium produces 1 mole of hydrogen

0.08 moles of sodium would produce 0.08 moles * 1 mole/ 2 moles

= 0.04 moles

Given that;

P = pressure

V = volume

n = Number of moles

R = gas constant

T = temperature

PV = nRT

P = nRT/V

P = 0.04 * 0.082 * 298/1

P = 0.98 atm

The partial pressure of the hydrogen = 0.98 atm

The partial pressure of the water = SVP of water at 18°C = 0.02 atm

Total pressure of the system =  0.98 atm +  0.02 atm = 1 atm

The system has a total pressure of 1 atm.

To find the energy gained by the iron sample, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = energy (J)

-----> m = mass (g)

-----> c = specific heat capacity (J/g°C)

-----> ΔT = T₂ - T₁ = change in temperature (°C)

T₂ represents the final temperature and T₁ represents the initial temperature. After you calculate the value of "Q", you need to convert the energy from joules (J) to kilojoules (kJ).

Q = ? J                                  c = 0.387 J/g°C

m = 24.6 g                         ΔT = 99.8°C - 23.0°C = 76.8°C

All of these properties are due to the chemical structure of the compound. The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable.

Explanation:

The chemical structure of the compound is responsible for all of these properties. The chemical structure includes the bonding angle, bond type, molecule size, and intermolecular interactions. Slight changes in the chemical structure can have a significant impact on the compound's properties.

A chemical compound is a substance made up of many identical molecules that contain atoms from more than one chemical element and are held together by chemical bonds. A molecule made up of only one element's atoms is thus not a compound.

An atom's valence shell electrons determine how it interacts with neighboring atoms, and thus its chemical properties. Because sodium and lithium both have one valence electron, their chemical properties are similar.

The number of electrons in an atom's outermost shell determines its reactivity, or proclivity to form chemical bonds with other atoms. This outermost shell is referred to as the valence shell, and the electrons found within it are referred to as valence electrons.

Thus, The chemical structure of the compound is responsible for all of these properties.

0.6 is the equilibrium constant for the given reaction.

To calculate the equilibrium constant (K) for the given reaction, we need to use the molar concentrations of the reactants and products at equilibrium. The equilibrium constant expression is given by:

\(K= [H_{2}O]^{2} / ([H_{2}^{2} * [O_{2}])\)

Given the moles of H2, O2, and H2O in the 8.1 L container, we can convert them to molar concentrations by dividing the number of moles by the volume:

[H2] = 1.83 moles / 8.1 L

[O2] = 2.33 moles / 8.1 L

[H2O] = 3.95 moles / 8.1 L

Substituting these values into the equilibrium constant expression, we have:

K = \((3.95 / 8.1)^{2}\) / (\((1.83 / 8.1)^{2}\) * (2.33 / 8.1))

Evaluating this expression and rounding to one decimal place, we find the equilibrium constant to be:

K ≈ 0.6

Therefore, the equilibrium constant for the given reaction is approximately 0.6.

Protons and neutrons make up the majority of an atom's mass because electrons have almost negligible mass. Consequently, an atom's mass in atomic mass units is determined by the sum of its protons and neutrons.

An element's mass number is determined by the sum of its proton and neutron counts: Protons and neutrons together make up mass. Simply deduct the number of protons, or atomic number, from the mass number to get how many neutrons each atom has.

This becomes significant when there is a mass number. It enables us to distinguish between elements known as isotopes that have differing numbers of neutrons.

Although protons and neutrons are similar in size, they are both significantly heavier than electrons (approximately 2,000 times as massive as an electron). A proton's positive charge is equivalent to an electron's negative charge in strength.

The HCl is very strong since its pH is equal to 0.17.

Explanation:

The reaction between CaCO₃ and HCl is:

CaCO₃(s) + 2HCl(aq) ⇄ CaCl₂(aq) + CO₂(g) + H₂O(l)     (1)    

The number of moles of CaCO₃ is:

\( n_{CaCO_{3}} = \frac{m}{M} \)

Where:

m: is the mass = 0.750 g

M: is the molar mass = 100.0869 g/mol

\( n_{CaCO_{3}} = \frac{0.750 g}{100.0869 g/mol} = 7.49 \cdot 10^{-3} moles \)

From the reaction (1) we have that 1 mol of CaCO₃ reacts with 2 moles of HCl, so the number of moles of HCl is:  

\( n_{HCl} = 2*7.49 \cdot 10^{-3} moles = 0.015 moles \)

Now, with the number of moles of HCl we can find its concentration:

\( C = \frac{n}{V} = \frac{0.015 moles}{22.25 \cdot 10^{-3} L} = 0.67 M \)

Finally, the pH of the acid is:

\( pH = -log([H^{+}]) = -log(0.67) = 0.17 \)

The pH obtained is very low, so the HCl is very strong.

Therefore, the HCl is very strong since its pH is equal to 0.17.

Molar mass of NaCl (sodium chloride) is 58.44 g/mol, while molar mass of CoCl2 (cobalt chloride) is 129.84 g/mol. Since both samples have same number of moles, it means that they contain same number of particles of their respective compounds. However, mass of each sample will be different due to the difference in molar mass.

For example, if we assume that both samples contain 1 mole of their respective compounds, then mass of NaCl sample will be 58.44 g, while  mass of CoCl2 sample will be 129.84 g. So, two samples have different masses but the same number of particles.

Substance A has a higher boiling point compared to Substance B when measured on the same temperature scale.

To compare the boiling points of Substance A and Substance B, which were measured using different temperature scales, we need to convert the temperatures to a single scale for accurate comparison. The boiling point of Substance A was reported as 245 K, and the boiling point of Substance B was reported as -92°C. To convert Substance B's temperature from Celsius to Kelvin, we need to add 273.15 to the Celsius value. Thus, -92°C + 273.15 = 181.15 K. Now, both temperatures are in Kelvin: Substance A boils at 245 K, and Substance B boils at 181.15 K. Comparing the temperatures, we find that Substance A boils at a higher temperature (245 K) than Substance B (181.15 K). Therefore, Substance A has a higher boiling point compared to Substance B when measured on the same temperature scale.

Answer:

(a) Elements are combined in a specific ratio. 2 atoms of hydrogen and 1 atom of oxygen make water. (b) The properties of water are different from that of oxygen and hydrogen.

A methane molecule (CH4) is considered symmetrical because it possesses a symmetric structure and exhibits symmetry operations.

Symmetry refers to a balanced arrangement of elements that can be divided into equal parts by a plane, axis, or center. In the case of methane, it exhibits several symmetrical characteristics.

Firstly, methane has a tetrahedral molecular geometry, with the carbon atom at the center and four hydrogen atoms positioned around it. This geometry ensures that the molecule is symmetrical in terms of its spatial arrangement.

Each hydrogen atom is located at one of the vertices of the tetrahedron, forming equal angles and distances with respect to the central carbon atom. This symmetry is maintained regardless of the orientation of the molecule.

Additionally, methane possesses rotational symmetry. It can be rotated around any of the carbon-hydrogen bonds, and the molecule will retain its overall appearance.

The symmetry of methane arises from its molecular structure and the equal distribution of electron density around the central carbon atom. The four hydrogen atoms are bonded to the carbon through sigma bonds, which have a cylindrical symmetry. This balanced arrangement of the atoms contributes to the overall symmetry of the molecule.

Answer:

When HCl (hydrochloric acid) and KOH (potassium hydroxide) are neutralized, they react to form water (H2O) and a salt (KCl). The balanced equation is:

HCl + KOH → KCl + H2O

In this reaction, one mole of HCl reacts with one mole of KOH to form one mole of water and one mole of KCl.

During titration of HCl with KOH, the point at which the reaction is complete is called the equivalence point. At the equivalence point, the moles of H+ ions and OH- ions are equal in the titration mixture.

Since one mole of HCl reacts with one mole of KOH, and H+ ions are present in HCl and OH- ions are present in KOH, the number of moles of H+ ions will be equal to the number of moles of OH- ions at the equivalence point.

Therefore, at the equivalence point, the number of moles of H+ ions will be equal to the number of moles of OH- ions in the titration mixture when HCl is exactly neutralized by KOH.

When the HCl is neutralized by KOH, the equivalence point is reached. During titration, the amount of HCl is determined using a basic solution of known concentration.

It is possible to calculate the amount of KOH required for complete neutralization if the initial concentration of the HCl solution is known. The balanced chemical equation for the reaction between HCl and KOH is:HCl + KOH → KCl + H2OThe stoichiometry of the reaction indicates that one mole of HCl reacts with one mole of KOH to produce one mole of H2O. Thus, the number of moles of H+ ions is equal to the number of moles of OH- ions when the equivalence point is reached.In an acid-base reaction, the number of moles of hydrogen ions (H+) produced by the acid is equal to the number of moles of hydroxide ions (OH-) produced by the base. When the HCl is exactly neutralized by the KOH, the number of moles of H+ ions is equal to the number of moles of OH- ions in the titration mixture.

This is due to the balanced chemical equation for the reaction, which shows that one mole of HCl reacts with one mole of KOH to produce one mole of water (H2O).Thus, at the equivalence point, the number of moles of H+ ions is equal to the number of moles of OH- ions. This is the point at which all of the HCl has reacted with the KOH. After the equivalence point, the excess KOH will react with the H2O to produce OH- ions, resulting in a basic solution.

Answer:

the answer is elastic potential energy to kinetic energy

Explanation:

A stretched rubber band contains potential energy (specifically called elastic potential energy because the material involved is elastic), which when released, the rubber band tries to return back to it's original shape and size. During the process of this return, the elastic potential energy is immediately converted to kinetic energy.

NOTE: Potential energy can be defined as the energy stored/present in a body at rest. It is usually as a result of the body's position or state. The potential energy stored in an elastic material is called elastic potential energy.

Kinetic energy can simply be described as the energy present in an object that is in motion.

One major process that is similar to the processes above is the mechanical energy, which is the energy involved in an object that has the ability to do work which in this case is a drawn elastic rubber that has the ability to "return" to it's initial state.
