Answer:
<h2><em><u>MASS</u></em></h2>
Explanation:
Inertia increases as an object's <u>Mass</u> increases.
Answer: The coefficient in front of AgCl when the equation is properly balanced is 2.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Decomposition of silver chloride is represented as:

Thus the coefficient in front of AgCl when the equation is properly balanced is 2.
