Question

what is the balanced equation for this reaction? hno₂ + nh₄oh → 2hno₂ + nh₄oh → 2nh₄no₂ + h₂o hno₂ + 2nh₄oh → nh₄no₂ + 2h₂o hno₂ + nh₄oh → nh₄no₂ + h₂o

Explanation:

Step1: Count atoms on both sides

For the reaction \(HNO_2+NH_4OH\to\), count \(H\), \(N\), \(O\) atoms.
In \(HNO_2\): \(1\) \(H\), \(1\) \(N\), \(2\) \(O\). In \(NH_4OH\): \(5\) \(H\), \(1\) \(N\), \(1\) \(O\).
On the product side, for \(NH_4NO_2\): \(4\) \(H\), \(2\) \(N\), \(2\) \(O\). For \(H_2O\): \(2\) \(H\), \(1\) \(O\).

Step2: Check balance

In \(HNO_2 + NH_4OH=NH_4NO_2 + H_2O\),

• \(H\): Left side \(1 + 5=6\), Right side \(4+2 = 6\)
• \(N\): Left side \(1 + 1=2\), Right side \(2\)
• \(O\): Left side \(2+1 = 3\), Right side \(2 + 1=3\)

Answer:

\(HNO_2+NH_4OH = NH_4NO_2 + H_2O\)
