When copper oxide is reacted with sulfuric acid, the acid is often gently heated. This is done in order to:
pav-90 [236]
Copper oxide(solid) + Sulphuric Acid (aqueous)-> Copper Sulphate (aqueous)+ Water(liquid)

In equation form:

CuO +H2SO4 -> CuSO4 + H2O

The colour change you will see is black to blue as Copper oxide is usually found as a black powder. Upon the reaction with sulphuric acid it will change to a cyan blue.

If you heat the made solution of copper sulphate, the water will evaporate and you will be left with white anhydrous copper sulphate crystals.

How many tons of zinc can be obtained from 976 tons of zinc ore that is 78.0% zinc carbonate?
kramer
First, calculating the amount of zinc carbonate by multiplying the given mass of the ore by the percent zinc carbonate. 
                          mass of zinc carbonate = (976 tons)(0.78) 
                                                       = 761.28 tons
Then, calculate for %Zn in zinc carbonate
                           %Zn = ((65.38) / (125.39)) x 100%
                                          % Zn = 52.141%
tons of Zn from the sample,
                           mass of Zn = (761.28 tons)(0.52141)
                                              = 396.94 tons Zn
