following equations :

a) A2O3 + 2B −−−−> B2O3 + 2A

b) 3CSO4 +2B −−> B2SO4 + 3C

c) 3CO + 2A −−−−> A2O3 + 3C

Answer the following:

i) Which element is most reactive?

ii) If an element D is least reactive write an equation to justify it.

iii) Arrange elements in the increasing order of their reactivities.​

Answer 1

Answer:

1. B is most reactive as it displaces both A and C

2. 2DO3+2C--->2CO3+2D

3. B>A>C
