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.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
