mass can be created and destroyed during a chemical reaction.
mass can be created but not destroyed in a chemical reaction.
mass cannot be created nor destroyed in a chemical reaction.
question 2
why is it important to balance a chemical equation?
to make sure you have the correct products
to obey the law of conservation of mass
it is not important to balance a chemical equation.
to make sure you have the correct reactants
question 3
what does conserving mass mean in a chemical equation?
there are more of each type of atom on the reactant side than on the product side.
there are more of each type of atom on the product side than on the reactant side.
there is an unequal number of each type of atom on both sides of the equation.
there is equal number of each type of atom on the reactant and product side

Explanation:

Question 1

The law of conservation of mass is a fundamental principle in chemistry. It states that in a chemical reaction, mass is conserved. This means that atoms are neither created nor destroyed. They are just rearranged.

Balancing a chemical equation is directly related to the law of conservation of mass. When an equation is balanced, the number of each type of atom on the reactant side is equal to the number on the product side, ensuring mass conservation.

Conserving mass in a chemical equation means that the quantity of each type of atom remains the same throughout the reaction. So, the number of each type of atom on the reactant side must equal the number on the product side.

Answer:

Mass cannot be created nor destroyed in a chemical reaction.
