A balanced chemical reaction obeys the law of...
Anit [1.1K]

Answer: (C) conservation of matter

Solution: Law of conservation of matter or mass states that' total mass of the reactants should always be equal to the total mass of the product that is the total mass is remained conserved in a chemical reaction.

A balanced chemical equation always follow this law.

For example:

2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

Mass of hydrogen = 1 g/mol

Mass of Oxygen = 16 g/mol

Total mass on the reactants = 2(2×1)+(2×16)= 36g/mol

Total mass on the product side = 2[(2×1) +16] = 36 g/mol

As,

Mass on reactant side = Mass on the product side

Therefore, a balanced chemical reaction follows Law of Conservation of mass.
