Question

Conversion factors can be generated based on a balanced chemical reaction. For the

reaction below, identify which conversion factor (equality) is not valid:
C(s) + O2(g) → CO2(g)

A: 1 mole CO₂ = 1 mole C
B: 1 mole CO₂ = 1 mole O2
C: 1 mole C = 1 mole O2
D: 2 moles O₂ = 1 mole CO2

Answer 1

D

Step-by-step explanation:

D. Since CO2 is the only product, all the oxygen has to be converted into the form of CO2.
Let's pretend for a minute that the equation is:
aC + 2O2 -> CO2 where a is a certain number.
There would be no way of balancing this equation because the amount of oxygen on the left would always be twice of that on the right.
