Answer from: coryintheswamp

D: 55 g

Explanation:

The law of conservation of mass states that in a chemical reaction, the mass of the reactants (left side of the reaction) must be equal to the mass of the products (right side of the reaction).

In this reaction, we have:

$A+B\rightarrow AB$

where A and B are the reactants, while AB is the product.

The mass of the reactants is:

m(A)+m(B)=10 g+45 g=55 g

So, the mass of the product (AB) should also be 55 g.

Answer from: mvtthewisdead

The correct answer is Option D.

Explanation:

The given chemical equation follows:

$A+B\rightarrow AB$

Every balanced chemical equation follows Law of Conservation of Mass. This law states that the total mass on the reactant side is equal to the total mass on the product side.

Total mass on the reactant side = (10 + 45)g = 55g

So, the total mass on the product side must be equal to 55 grams only. Thus, 55 grams of AB will be produced in the reaction.

Hence, the correct answer is Option D.
