Good Day

In an experiment, some benzene and oxygen were placed in a sealed steel container, weighed, and ignited with an electric spark to make them chemically react. The resulting carbon dioxide and water, still in the sealed steel container, were weighed again.

• The chemical formula of Benzene is C₆H₆ which react to O₂ to produce H₂O + CO₂
• The chemical reaction presented on the problem is combustion reaction in which hydrocarbon react with oxygen to produce water and carbon dioxide.

Chemical equation:

                               C₆H₆  + O₂ ⇒ H₂O + CO₂

Balance chemical equation:

                               2C₆H₆  + 15O₂ ⇒ 6H₂O +  12CO₂

Which law is being investigated?

• Law of Conservation of Mass

During chemical reaction, atoms are not destroyed and no creation of new elements. Since atom are not destroyed and the element of the product is the same element in the reactant therefore, the mass of the product is equal to the mass of the reactant. This is also the main reason why we balance the chemical reaction, since the mass of reactant is equal to the mass of the product.
