Question

1. what are the products of the chemical equation to make a balanced chemical equation

2h₂o + 1o₂ → h₂o₂
a. 1h₂o₂
b. 2h₂o₂
c. 3h₂o₂
d. 4h₂o₂

Explanation:

Step1: Count H atoms on reactants

Reactants: $2\text{H}_2\text{O}$ has $2 \times 2 = 4$ H atoms; $\text{O}_2$ has 0 H atoms. Total H = 4.

Step2: Match H atoms in product

Each $\text{H}_2\text{O}_2$ has 2 H atoms. Moles of $\text{H}_2\text{O}_2$ needed: $\frac{4}{2}=2$.

Step3: Verify O atom balance

Reactants: $2\text{H}_2\text{O}$ has $2 \times 1 = 2$ O; $\text{O}_2$ has 2 O. Total O = 4.
Product: $2\text{H}_2\text{O}_2$ has $2 \times 2 = 4$ O. Balanced.

Answer:

b. $2\text{H}_2\text{O}_2$
