Question

Why must chemical equations be balanced? Question 3 options: to show that sometimes the amounts of atoms vary to represent conservation of energy to represent conservation of mass to make the chemical reaction work as planned

Answer 1

To represent conservation of mass

Step-by-step explanation:

just took the test :D

hope this helps, and God be with you!!

Don't forget to be stunning! :D

Answer 2

Answer: To represent conservation of mass.

Step-by-step explanation:

As the law given by Antoine Lavoisier which states that " in a chemical reaction, mass before and after the reaction remains the same that is mass remains conserved in a chemical reaction" which is known as Law of Conservation of Mass.

Total mass of the reactants = Total mass of the products

So, in order to represent the conservation of mass chemical equation should always be balanced.
