When most fuels burn, water and carbon dioxide are the two main products. however, water and carbon dioxide are not the products of all combustion reactions. which will not form water and carbon dioxide when it burns?
a) ch4
b) c6h12o6
c) h2

The correct answer is Option C.

Explanation:

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule. The chemical equation for this reaction follows:

Hydrocarbon are defined as the substances in which hydrogen and carbon atoms are covalently bonded. Elements other than carbon and hydrogen can also be present.

For the given options:

Methane can undergo combustion reaction and produce carbon dioxide and water because it is a hydrocarbon. The chemical equation follows:

Glucose can undergo combustion reaction and produce carbon dioxide and water because it is a hydrocarbon. The chemical equation follows:

Hydrogen can undergo combustion reaction and will produce only water as a product. The chemical equation follows:

Hence, the correct answer is Option C.
