Question

Arrange the following in order of their increasing reactivity :
Mg, Zn, Cu, K​

Answer 1

Answer:

Whereas Cu, Ag, Au belongs to same group where Cu is the most reactive and Au is the least reactive in nature. Also, Zinc is able to displace iron in a solution. Hence, Zn is more reactive than Fe. Hence, we can conclude metals in order of increasing reactivity as follows.

Explanation:

Hope it helps.

Answer 2

Answer:

Arrange the following in the increasing order of their reactivity:

Ca,Cu,Hg,Al,Ag,K,Zn

Ans : According to the Reactivity series:-

K>Na>Ca>Mg>Al>Zn>Fe>Sn>Pb>Hg>Cu>Ag>Au

Therefore, according to question, increasing order of their reactivity is Ag<Cu<Hg<Zn<Al<Ca<K.
