Question
When heated, lead nitrate decomposes according to the following equation. What is the coefficient for NO₂ when the equation is balanced with the smallest whole number coefficients? Pb(NO₃)₂ → PbO + O₂ + NO₂
Correct Answer
Option D is the correct answer.
Detailed Explanation
Balanced equation: 2Pb(NO₃)₂ → 2PbO + 4NO₂ + O₂. Coefficient of NO₂ is 4.
Hint
Balance O and N carefully.
