During the displacement reaction a student observe that the metal P can displace Q from its salt solution. But Q cannot displace R from its salt solution. Based on the above observation a) Name the most reactive metal. b) Name the salt formed when P displace Cu from CuSO 4 solution.

See the answer below

Explanation:

P can displace Q from its salt solution means that P is more reactive than Q.

Q cannot displace R from its salt solutions means that R is more reactive than Q.

a) There is no information as to which of P and R has the capacity to displace one another from their salt solutions. Hence, the most reactive metal can be either of P and R.

b) When P displaces Cu from CuSO4 solution, the equation can be represented below (assuming that P is monoatomic):

Hence, the product formed is

the answer is b. dilution
