Question

What is meant by the law of conservation of mass? If 12g of c is burnt in the presence of 32g of oxygen,how much co2 will be formed?

Answer 1

The law of conservation of mass states that in a chemical reaction, mass can neither be created nor destroyed. It means that mass of reactants is always equal to the mass of products. It was given by Antoine Lavoisier.

Mass of carbon=12 g

Mass of oxygen=32 g

Mass of carbon dioxide=12+32

=44 g

Answer 2

answer

mass of carbon dioxide is 44 g
