Question

Observe the three chemical equations given below. Among the elements A, B and C, identify the

element which is most reactive and which is least reactive?

A2O3 + 2B --→ B2O3 +2A

3CSO4 + 2B --→ B2(SO4)3 + 3C

3CO + 2A ---→ A2O3 + 3C​

Answer 1

Answer:

a) Element B is the most reactive element compared to A and C because element B is able to displace A and C from their oxides.

b) Element C is least reactive because it gets displaced from oxide or sulfide form when element A and B react with when it is in compound form.
