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 21 g of A completely reacts with 22 g of B to produce 17 g of C, how many grams of D will be produced?

Respuesta :

Answer:

26 grams of D will be produced.

Explanation:

The reaction is given by:

A + B ----->  C + D

Mass of A reacted = 21 g

Mass of B reacted = 22 g

Mass of C formed = 17 g

Mass of D formed = m =?

According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.

Then:

mass of A reacted + mass of B reacted = mass of C formed + mass of D formed

21 + 22 = 17 + m

m = 26 g
