2 C2H6 + 7 026 H2O + 4 CO2 If 5.25 moles of ethane (C2H6) and 15.0 moles of oxygen are reacted,
which is the limiting reactant?

Oxygen is limiting reactant

Explanation:

Based on the chemical reaction:

2C2H6 + 7O2 → 6H2O + 4CO2

2 mole of ethane reacts with 7 moles of oxygen

For a complete reaction of 5.25 moles of ethane are required:

5.25 moles Ethane * (7mol Oxygen / 2mol Ethane) = 18.38 moles of oxygen

As there are just 15.0 moles of oxygen
