Why must both sides of a chemical equation balance?
chemical reactions cannot destroy matter
the number of atoms involved in the reaction must equal the number in the end product
"what goes in must come out"
all of the above
Answers
A.
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
B.
In reactions under normal laboratory conditions, matter is neither created nor destroyed, and elements are not transformed into other elements. ... Because matter is not created or destroyed in a chemical reaction, the total mass of reactants is the same as the total mass of products.
C.
Because atoms are neither created nor destroyed in a chemical reaction, the total mass of products in a reaction must be the same as the total mass of the reactants.
