The complete combustion of phenylhydrazine,C₆H₅NHNH₂,with the oxidizer dinitrogen tetraoxide is shown in the following equation:
__ C₆H₅NHNH₂ + __ N₂O₄ → __ CO₂ + __ H₂O + __ N₂
When this equation is balanced,the sum of all the coefficients (using smallest whole numbers) is

Question

Quizplus · Accepted Answer

Balancing the equation by starting with the carbon atom, we get:
C6H5NHNH2 + 4N2O4 → 6CO + 5H2O + 4N2
Coefficients: 1, 4, 6, 5, 4
Sum of coefficients = 1 + 4 + 6 + 5 + 4 = 20. 
Therefore, the answer is choice B.
