Question

What is law of conservation of mass? ​

Answer 1

Answer:

Explanation:

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.

Answer 2

Answer:

• law of conservation of mass is a low proposed by Lavoiser in 1789
• this law states that total mass of reactant is equal to total mass of product
• eg: h2 (2g ) + 1/2 O2(16g) = h2o (18g)
• this is a theoretical aspect
• the limitation is that radioactive reactions because in this reaction the mass is converted into energy
