The combustion of ethane (c2h6) produces carbon dioxide and steam. 2c2h6(g)+7o2(g)⟶4co2(g)+6h2o(g) how many moles of co2 are produced when 5.60 mol of ethane is burned in an excess of oxygen?

11.2 moles of are produced when 5.60 mol of ethane is burned in an excess of oxygen.

Explanation:

The combustion of ethane is represented using balanced chemical equation:

As oxygen is preset in excess, ethane acts as the limiting reagent as it limits the formation of product.

According to stoichiometry :

2 moles of propane produces 4 moles of carbon dioxide

Thus 5.60 moles of propane will produce= moles of carbon dioxide

Thus 11.2 moles of are produced when 5.60 mol of ethane is burned in an excess of oxygen.
