Question

15.
The following observations are given for four metals.
1) Metal H does not react with dilute HCI.
ll) Metal K reacts with warm water.
III) Metal L does not react with water but displaces metal H from its aqueous salt solution.
lV) Metal M reacts with cold water.

Choose the correct decreasing order of reactivity of these metals amongst the following.
1)M>L>H >K 2) K>M>H>L 3) M > k>L>H 4) L>H>K>M​

Answer 1

Answer:

3 is the answer and as reactivity series follows cold warm hot

Answer 2

Answer:

M > K > L > H
