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:

Step1: Identify reactants

Each grey - red pair is CO, and there are 2 of them. Each blue - red pair is NO, and there are 2 of them. So the reactants are 2CO and 2NO.

Step2: Identify products

Each grey - two reds pair is CO₂, and there are 2 of them. The blue - blue pair is N₂. So the products are 2CO₂ and N₂.

Answer:

D. 2CO + 2NO → 2CO₂ + N₂
