Answer: The balanced chemical equation for the combustion of benzene is:

Explanation:
Combustion reactions : It is defined as the reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water as a product.
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
The balanced chemical equation for the combustion of benzene will be:

By Stoichiometry of the reaction we can say that,
2 mole of benzene reacts with 15 moles of oxygen gas to produce 12 moles of carbon dioxide and 6 moles of water molecule.
The process of a chemical change is when it occur when a substance called chemical synthesis or alternatively chemical decomposition into two or more different substances
Answer:
A
Explanation:
When molecules speed up, they become excited and create friction that is transformed into heat, do when an abject cools, the molecules slow down and thus for have less friction.
An explanation or answer based on the facts or evidence you have.
