How does a chemical reaction obey the law of conservation of matter?
a)the same number of reactant particles as product particles are involved in the reaction.
b)the same total number of chemical bonds are in the reactants as are in the products.
c)the same number of molecules appear in the reactants as appear in the products.
d)the total mass of the reactants is equal to the total mass of the products.

D)The total mass of the reactants is equal to the total mass of the products.

Explanation:

Law of conservation of energy states that matter can neither be created nor be destroyed but it can change from one form to another.

In a chemical reaction, the total mass of the reactants and the total mass of products remains the same. The same amount of matter ends up in the product as was the total mass in the reactants. The conservation of mass will be depicted in a balanced chemical equation.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
