Question

Use the chemical equation to find the answers.

H2CO3 → H2O + CO2

Identify how many oxygen atoms are in the product.

Identify how many oxygen atoms are in the reactant.

Answer 1

In the given chemical equation:

\[
\text{H}_2\text{CO}_3 \rightarrow \text{H}_2\text{O} + \text{CO}_2
\]

Let's break it down:

1. **Reactant (H2CO3)**:
- The formula H2CO3 (carbonic acid) contains:
- 3 oxygen atoms (from CO3).

2. **Products (H2O and CO2)**:
- H2O contains 1 oxygen atom.
- CO2 contains 2 oxygen atoms.
- Therefore, in total, the products contain:
- 1 (from H2O) + 2 (from CO2) = 3 oxygen atoms.

**Summary**:
- Number of oxygen atoms in the reactant (H2CO3): **3**
- Number of oxygen atoms in the products (H2O + CO2): **3**
