Question

A + B + C → D + E

Answer 1

I believe it is B... because all balance equation are supposed to follow the law of conservation of mass

Answer 2

Answer: The correct answer is Option B.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.  

This also means that total mass on the reactant side must be equal to the total mass on the product side.

For the given chemical reaction:

$A+B+C\rightarrow D+E$

Total mass on reactant side = Total mass on product side

Hence, the correct answer is Option B.
