Question

Write the complete balanced equation for the reaction that occurs when C6 H6 combusts in O2. (4 points)

Answer 1

Answer: The balanced equation is given below.

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. This also means that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

The given balanced chemical equation follows:

$2C_6H_6+15O_2\rightarrow 12CO_2+6H_2O$

By Stoichiometry of the reaction:

2 moles of benzene reacts with 15 moles of oxygen gas to produce 12 moles of carbon dioxide and 6 moles of water molecule.

Answer 2

2(C6H6) + 15(O2) = 12(CO2) + 6(H2O)
