6 0

Explanation:

the word equation for corrosion of copper is 4Cu+O2 > 2Cu 2O

the word equation for combustion of octane is 2 C8H18 + 25 O2 -> 16 CO2+18

A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

4.The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
