Answer :

Certainly! Let's break down the details of the reaction given by the chemical equation:

[tex]\[ 2H_2(g) + O_2(g) \rightarrow 2H_2O(l) \][/tex]

### 5. What name describes the product in this reaction?

The product of this reaction is water.

### 6. What names describe the reactants?

The reactants for this reaction are:
- Hydrogen gas ([tex]\(H_2\)[/tex])
- Oxygen gas ([tex]\(O_2\)[/tex]).

### 7. What are the physical states of the reactants in this reaction?

The physical states of the reactants are both in the gaseous state.

### 8. What is the physical state of the product?

The physical state of the product, water ([tex]\(H_2O\)[/tex]), is liquid.

### 9. What do the coefficients tell you about the ratio of the reactants?

The coefficients in the balanced chemical equation indicate the molar ratio of the reactants. For this reaction, the coefficients indicate that for every [tex]\(2\)[/tex] moles of hydrogen gas ([tex]\(H_2\)[/tex]), there is [tex]\(1\)[/tex] mole of oxygen gas ([tex]\(O_2\)[/tex]) reacting. Thus, the ratio of hydrogen gas to oxygen gas is 2:1.

### 10. How many units of the product are produced?

According to the balanced equation, [tex]\(2\)[/tex] units (or moles) of water ([tex]\(H_2O\)[/tex]) are produced from this reaction.

In summary:
- The product is water.
- The reactants are hydrogen gas and oxygen gas.
- Both reactants are in the gaseous state.
- The product, water, is in the liquid state.
- The ratio of hydrogen gas to oxygen gas is 2:1.
- The reaction produces 2 units of water.
