Use the law of conservation of mass to answer the questions. Consider a hypothetical reaction in which A and B are reactants and C and D are products. If 19 g of A completely reacts
with 24 g of B to produce 15 g of C, how many grams of D will be produced?
mass of D:

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In terms of a chemical reaction, the mass of the reactants has to equal the mass of the products.

The reactants are A and B. The mass of A is 19 grams and the mass of B is 24 grams. Add the masses.

19 g + 24 g= 43 g

This is the mass of the reactants.

The products and C and D. The mass of C is 15 grams. The mass of the products has to equal the mass of the reactants, which is 43 grams. Subtract 15 from 43 to find D's mass.

43 g - 15 g= 28 g

28 grams of D will be produced.

The answer is c fish
