Question

Sonia had three metals X,Y,Z. She wanted to arrange them in the decreasing order of reactivity. For this , she carried out some chemical tests and observed the following reactions:-

1) XCL3 + Y ----> YCL3 + X
2) ZO + Y ----> Y2O3 + Z
3) ZSO4 + X ----> X2SO4 + Z

Based on the above reactions, and the following questions :-

1 Which of the three metals is the most reactive?
2 Which of the three metals is the least reactive?
3 Arrange the three metals in order of there reactivity.
Pls and fast!!!!!

Answer 1

Y>X>Z because Y replaces all metals from salt solution ,X replaces Z and Z replaces none
