Question

List the number and name of the bonds broken and formed in the following reaction.
H2 + O2 -> 2 H2O

Answer 1

In the reaction \( \text{H}_2 + \text{O}_2 \rightarrow 2 \text{H}_2\text{O} \), the following bonds are broken and formed:

**Bonds Broken:**
1. 1 O=O bond from \( \text{O}_2 \) (the double bond between the two oxygen atoms)
2. 2 H-H bonds from 2 \( \text{H}_2 \) molecules (one bond from each hydrogen molecule)

**Bonds Formed:**
1. 4 O-H bonds (two O-H bonds in each of the two water molecules, for a total of four)

So, to summarize:
- **Bonds Broken:** 1 O=O, 2 H-H
- **Bonds Formed:** 4 O-H
