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?
1 answer:
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
