Question

A + B + C → D + E

Describe the mass of the reactants and products given the balanced chemical reaction.
A. The mass of the products is 2/3 that of the reactants.
B. The mass of the reactants equals the mass of the products.
C. The mass of the reactants is less than the mass of the products.
D. The mass of the reactants is greater than the mass of the products.

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.
