Question

X, Y & Z are three elements which undergo chemical reactions according to following equations.
X203 + 2Y → Y203 + 2X
3ZSO4 + 2Y → Y2(SO4)3 + 3Z
3ZO + 2X →
X₂O3 + 3Z
Which element is the most reactive ?​

Answer 1

Answer:

Y

Explanation:

X is dispace by Y in First reaction while Z is displace by Y in second reaction and z is displace by X also in third reaction.

Means Z is least reactive and Y is most reactive
