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

For example, mass, density, volume etc are all physical changes.

On the other hand, a change that brings change in chemical composition of a substance is known as chemical change.

For example, combustion, toxicity, reactivity etc are all chemical changes.

Hence, following statements are identified as chemical or physical changes as follows.

(a) Oxygen gas supports combustion : Chemical change

(b) Fertilizers help to increase agricultural production : Chemical change

(c) Water boils below 100^{o}C on top of a mountain : Physical change

(d) Lead is denser than aluminum : Physical change

(e) Uranium is a radioactive element : Chemical change
