Question

What is the order of decreasing reactivity keeping in view the following reactions?
A+ BSO4 → ASO4 + B
B + 2CNO3 + B(NO3)2 + 2C
A + C20 → AO + 2C
B>C>A
B>A>C
A> A>B>C

Answer 1

Answer:

The answer is a option B

Answer 2

Answer:

A>B>C

Explanation:

A can displace both B and C, Hence A is the most reactive metal. B can displace C so it is reactive than C

Hence the decreasing order of the reactivity is

A > B > C
