Hydrocarbon+O_2\rightarrow H_2O+CO_2

For example : Ethane react with oxygen to give carbon dioxide and water.

C_2H_8+4O_2\rightarrow 2CO_2+4H_2O

Which statement best describes balancing equations and the law of conservation of mass?
max2010maxim [7]

Answer:

The number of atoms is the same in the reactants and in the products, and the total mass is the same in the reactants and in

the products

Explanation:

For an equation to termed balance, the number of atoms of elements in the reactants must be equal to the number of atoms of the same element in the product.

The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but changes from one form to another. An unbalanced equation simply means that matter have been created or destroyed. This implies that balancing equation supports the laws of conservation of mass
