Question

The reaction of 15 moles carbon with 30 moles O2 will

result in a theoretical yield of __ moles CO2.

Answer 1

15 moles.

Step-by-step explanation:

Hello,

In this case, the undergoing chemical reaction is:

`C+O_2\rightarrow CO_2`

Clearly, since carbon and oxygen are in a 1:1 molar ratio, 15 moles of carbon will completely react with 15 moles of oxygen, therefore 15 moles of oxygen remain as leftovers. In such a way, since carbon and carbon dioxide are also in a 1:1 molar ratio, the theoretical yield of carbon dioxide is 15 moles based on the stoichiometry:

`n_(CO_2)=15molC*(1molCO_2)/(1molC) \\\\n_(CO_2)=15molCO_2`

Best regards.
