Use the reaction equation below to determine the molar ratio of acetylene (c2h2) to carbon dioxide (co2).

2 to 5
1 to 2
1 to 1
5 to 4

The correct ratio molar for this reaction is 1 to 2

Explanation:

The following is the balanced reaction

2C2H2 + 5O2 > 4CO2 + 2H2O

In where do we have

4 Carbon molecules

4 Hydrogen molecules

10 Oxygen molecules
