Question

Which set of coefficients balances this equation?

?NO + ?CO_2 → ?CO + ?N_2

(a) 1, 1, 1, 1
(b) 1, 2, 2, 1
(c) 2, 1, 2, 1
(d) 2, 1, 1, 2

Answer 1

The correct set of coefficients to balance the equation NO + CO2 → CO + N2 is 1, 2, 2, 1.

Step-by-step explanation:

The chemical equation mentioned is NO + CO2 → CO + N2. To balance this equation, we need to equalize the number of atoms of each element on both sides of the equation. After analyzing the equation, the correct set of coefficients to balance the equation is option (b) which is 1, 2, 2, 1.

This means the balanced equation would be 1NO + 2CO2 → 2CO + 1N2, with each element having the same number of atoms on each side of the equation.
