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.

1 answer

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
