Answer:
Explanation:
Hello!
In this case, since the percent water is computed by dividing the amount of water by the total mass of the hydrate; we infer we first need the molar mass of water and that of the hydrate as shown below:
Thus, the percent water is:
So we plug in to obtain:
Best regards!
The correct option is (a) H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2
<h3>What is molar Ratio ?</h3>
Molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation
the balanced equation is as follows ;
2H₂S + 3O₂ --> 2SO₂ + 2H₂O
molar ratio can be determined by the coefficients of the compounds in the balanced reaction.
coefficient is the number in front of the chemical compound
coefficients for the compounds in this reaction are as follows ;
- H₂S - 2
- O₂ - 3
- SO₂ - 2
- H₂O - 2
therefore, correct option is (a) H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2

During endothermic phase change, the potential energy of the system always increases while the kinetic energy of the system remains constant. The potential energy of the reaction increases because energy is been added to the system from the external environment.
<u>Explanation</u>:
- Those are three distinct methods for demonstrating a specific energy condition of an object. They don't affect one another.
- "Potential Energy" is a relative term showing a release of possible energy to the environment. If we accept its pattern as the overall energy state of a compound, at that point, an endothermic phase change would infer an increase in "potential" as energy is being added to the compound by the system.
- A phase change will display an increase in the kinetic energy at whatever point the compound is transforming from a high density to a low dense phase. The kinetic energy will decrease at whatever point the compound is transforming from a less dense to high dense phase.
I think it's covalent...? Hope that helps.
