At very high temperatures, copper(ii) sulfate undergoes the reaction cuso4(s) --> cuo (s) + so3 (g)

what kind of reaction is this?

if 319.22 g cuso4(s) reacted completely in the reaction, how many grams of cuo(s) would be produced?

a) Decomposition

b) 159.0 g of CuO(s) would be produced.

Explanation:

Decomposition reaction is a chemical reaction in which one reactant gives two or more than two products. They are endothermic reactions as energy is required to break the bonds of the reactants.

As can be seen from the given balanced reaction:  

1 mole of gives 1 mole of .

Thus 159.6 g of   gives 79.5 g of .

319.22 g of   will give=of .
