Answer:
c equal
Explanation:
1,)This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants
2)a gas
3) plasma

Answer:
written below-
Explanation:
.Ans= According to the laws of conservation mass, the total mass of products in a chemical reaction must be equal in a mass of reactant.
2 Ans= Gases are highly compensable and negligible force of attraction between particles.
3.Ans= At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas.
