b) What do you mean by  the term ‘reactants’?


               5.       You have 100 ml copper sulphate solution in a 250 ml             Hots     5
                        beaker. A small piece of magnesium ribbon is dropped into
                        the solution.

                        Some chemical reaction takes place with change in colour
                        and deposition of metal.

                           a)  What type of chemical reaction takes place?
                           b)  Which colour change is observed during this
                               reaction?
                           c)  Name the metal which gets deposited.
                           d)  Write the word and chemical equation for the above
                               reaction.
