Question

Calculate the maximum amount of ZnS formed when 6.53gm of zinc is heated with 5gm of sulphur

Answer 1

The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction.

So, Zn + S = ZnS

  6.53 + 5 = 11.53gm

So the maximum amount of ZnS formed is 11.53gm
