Question

Which of the following is a valid mole ratio from the balanced equation 2C3H6 + 9O2 → 6CO2 + 6H2O?

A) 1 mol C3H6 / 2 mol CO2
B) 6 mol CO2 / 6 mol H2O
C) 3 mol H2O / 2 mol CO2
D) 2 mol C3H6 / 9 mol O2

Answer 1

The valid mole ratio from the balanced chemical equation is 2 mol C3H6 / 9 mol O2, which corresponds to option D in the provided options.

Step-by-step explanation:

The correct mole ratio from the balanced equation given is 2 moles of C3H6 to 9 moles of O2. This corresponds to option D in the question. The balanced chemical equation states that 2 moles of C3H6 react with 9 moles of O2 to produce 6 moles of CO2 and 6 moles of H2O. Therefore, the valid mole ratio can be represented as 2 mol C3H6 / 9 mol O2, which directly reflects the coefficients from the balanced equation mentioned previously.
