Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . suppose 23. g of ethane is mixed with 147. g of oxygen. calculate the minimum mass of ethane that could be left over by the chemical reaction. be sure your answer has the correct number of significant digits.

The minimum mass of ethane that could be left over by the chemical reaction is zero.

Explanation:

Moles of ethane =

Moles of oxygen gas :

Since, 2 moles of ethane gas react with 7 moles of oxygen gas.

Then 0.7666 mol of ethane gas will react wit:

This means that ethane gas is in limited amount.hence ethane is a limiting reagent. Where as oxygen in present in excessive amount.

All the moles ethane gas will go under combustion reaction leaving zero moles behind.
