The equation below shows a general equation for a reaction, and the amounts of the substance are written underneath.

AB + CD → AC + BD
(15 g) (?) (?) (10 g)

The total mass of the products is 50g. Which best completes the other two amounts?

The amount of CD is 40 g, and the amount of AC is 35 g.
The amount of CD is 35 g, and the amount of AC is 40 g.
The amount of CD and AC would be the same.
The amount of CD and AC is undetermined.

Use conservation of mass. Total reactants = total products = 50 g. With AB = 15 g, CD = 50 − 15 = 35 g. With BD = 10 g, AC = 50 − 10 = 40 g.

So: CD = 35 g and AC = 40 g.
