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).
