Question

select the correct answer
in this equation stands for carbon, stands for nitrogen, and stands for oxygen. which equation represents this reaction?
a. 2co + 2no - 2cn₂ + o₂
b. co + no - 2co₂ + 2n₂
c. 2co₂ + 2no - co₂ + n₂
d. 2co + 2no - 2co₂ + n₂

Explanation:

Reactants: 2 molecules of CO (1 C + 1 O) and 2 molecules of NO (1 N + 1 O). Products: 2 molecules of CO₂ (1 C + 2 O) and 1 molecule of N₂ (2 N). Option D matches this composition and stoichiometry.

Answer:

D. 2CO + 2NO → 2CO₂ + N₂
