Question 2 • Chemistry

The balanced equation shows the products that are formed when butane open paren cap c sub 4 cap h sub 10 close paren is combusted. 2 cap c sub 4 cap h sub 10 plus 13 cap o sub 2 rightarrow 8 CO sub 2 plus 10 cap h sub 2 cap o What is the mole ratio of butane to carbon dioxide?

Answer
A
ratio of 13 to 10
B
ratio of 1 to 5
C
ratio of 2 to 8
D
ratio of 13 to 8

Explanation

Use the coefficients in the balanced equation: 2 moles of butane produce 8 moles of carbon dioxide. Therefore, the mole ratio of butane to carbon dioxide is 2 to 8, which is choice C.
