Question

the gas hydrazine N2H2 burns in oxygen. count and list the bonds broken in this reaction

Answer 1

To determine the bonds broken when hydrazine (N₂H₂) burns in oxygen (O₂), we first need to look at the chemical reaction for the combustion of hydrazine. The overall reaction can be simplified as:

\[ \text{N}_2\text{H}_2 + \text{O}_2 \rightarrow \text{N}_2 + \text{H}_2\text{O} \]

Next, let’s identify the bonds involved.

### Reactants:
1. Hydrazine (N₂H₂):
- 1 N-N bond (between the two nitrogen atoms)
- 2 N-H bonds (between each nitrogen and hydrogen)

2. Oxygen (O₂):
- 1 O=O bond (the double bond between the two oxygen atoms)

### Bonds in Reactants:
- 1 N-N bond
- 2 N-H bonds
- 1 O=O bond

### Total Bonds Broken:
So, counting all the bonds broken during the reaction:
1. **N-N bond** from N₂H₂
2. **2 N-H bonds** from N₂H₂
3. **O=O bond** from O₂

### Summary:
The total number of bonds broken in the combustion of hydrazine in oxygen is:
- 1 (N-N)
- 2 (N-H)
- 1 (O=O)

**Total: 4 bonds broken** (1 N-N, 2 N-H, 1 O=O).
