Question

out of the two metals P and Q, P is less reactive than Q suggest an activity to arrange these metals in the order of their decreasing reactivity. support your answer with a suitable chemical equation. ​

Answer 1

A pleasure afternoon my dear friend,

Activity -

Take a salt of P and make solution of it with water. Now make a reaction of it with Q.

$P salt + Q \: gives \: out \: Q salt + P$

You will see that a salt of Q is formed and P is seperated out .

Thus from this activity we get Q is more reactive than P.

So decreasing series of metal =

Q and then P

Hope it helps

Answer 2

Answer:

Activity: Metal Q is added to salt solution of P, Q being more reactive, displaces metal P from its salt solution.

Chemical equation : Metal Q + Salt solution of P → Salt solution of Q + Metal P.

hope this helps you....
