Question

Why can metals high up in the reactivity series not be obtained by reduction of their oxides by carbon ?

Study the experimental set-up shown in the diagram and write chemical equation for the chemical reaction involved. Name and define the type of reaction. List two other metals which can be used in place of iron to show the same type of reaction with copper sulphate solution.

Which one of the following reactions is different from the remaining three ?

"No precipitation reaction can occur without exchange of ions between the two reactants." Justify this statement giving a balanced chemical equation for the reaction.

Giving one example of each, differentiate between a displacement reaction and a double displacement reaction.
