According to the reaction below,if 24 moles CO2 were produced,how many moles of C2H6 were reacted?

2C2H6+7O2 -> 4CO2+6H2O

24 moles of CO2 *(2 moles of C2H6/4 moles of CO2) =12 moles of C2H6

To determine the number of moles of C2H6 reacted, we need to use the stoichiometry of the balanced chemical equation. The coefficients of the balanced equation indicate the molar ratios between the reactants and products.

From the balanced equation:
2 moles of C2H6 react to produce 4 moles of CO2.

Therefore, the molar ratio is:
2 moles of C2H6 : 4 moles of CO2

Since the question provides the number of moles of CO2 produced (24 moles), we can use this information to find the moles of C2H6 reacted.

To find the moles of C2H6, we can set up a proportion:

2 moles of C2H6 / 4 moles of CO2 = x moles of C2H6 / 24 moles of CO2

Cross-multiplying, we get:
2 * 24 = 4 * x

48 = 4x

Dividing both sides by 4, we find:
x = 48 / 4

x = 12

Therefore, if 24 moles of CO2 were produced, it means that 12 moles of C2H6 were reacted.
