Answer 1

Explanation:

(i) In increasing order

S<R<P<Q ( s has less reactivity and and Q has the most.)

(ii) Q is the most reactive and it displaces even Na from its salt solution so it will surely replace Cu as it is less reactive than.

Therefore CuSO₄ + Q → QSO₄ + Cu Here as no valency is given the product may be even Q₂SO₄ and so on...
