As long as the equation is correctly balanced, the mass of the reactants and products will be the same. That's the Law of Conservation of Matter.

What are substance you start with in a chemical reaction called?
The reactants
Which do the following best describes a neutralization reaction?
A neutralization reaction has as reactants a base and an acid and as products water and a salt.
Are reactants listed on the left or right of a chemical equation?
This statement would be...false.The reactants are located on the left, and the products are located on the right.This is desmond thaxs so much it helped =)
What are the reactants and the products of a written chemical reaction?
reactants are on the left and the products are on the right
How is the equilibrium of a reaction determined?
Molarity of products divided by reactants Keq=(products)/(reactants)
which of the following describes an endothermic reaction?
Hf, products > hf, reactants
Which of the following undergoes change during a chemical reaction?
The reactants are transformed in the products.
What of the following characterizes reaction at equilibrium?
The reactants concentration is equal to products concentration.
What are the reactant of a reaction?
Reactants are the starting materials of a reaction. Reactants combine to form the products.
The products in a decomposition reaction?
The products in a decomposition reaction depend on what the reactants are in that decomposition reaction. The products will be different depending on the reactants.
Materials at the end of a reaction?
before reaction = reactants after reaction = products
What are substance you start with in a chemical reaction called?

Which do the following best describes a neutralization reaction?
A neutralization reaction has as reactants a base and an acid and as products water and a salt.
What are the reactants and the products in the following 2H2O2 2H2O plus O2?
Reactants: Hydrogen Peroxide and Peroxidase Products: Water and Oxygen :) Hope this helped you!
What are substances that provide energy as the result of a chemical change?
These substances are called reactants, the reaction produces products. This type of reaction is called exothermic. As in the following reaction with the burning of methane: CH4 +2O2 ---> CO2 + 2H2O (reactants) (products)
Are reactants listed on the left or right of a chemical equation?
This statement would be...false.The reactants are located on the left, and the products are located on the right.This is desmond thaxs so much it helped =)
A reaction that can be made to go either direction from reactants to products or from products to reactants is called an?
Chemical Reaction
