Question

in an experiment 15.9 5 G of copper sulphate with 8.0 G of sodium hydroxide to form 9.75 G of copper hydroxide and X gram of sodium sulphate find the value of x which were of chemical combination as illustrated by this data

Answer 1

Answer:

I hope it's helpfull

Explanation:

The law of conservation of mass is illustrated by this data.

The mass of products = The mass of reactants

CuSO4 +NaOH → Cu

(OH)2 +NaSO4

(15.95 g) (8 g) (9.75 g) (14.2g)

Total mass of reactants = (15.95 g + 8 g) = 23.95 g

Total mass of products = (9.75 g + 14.2 g) = 23.95 g

Hence, Law of conservation of mass is valid here.
