Question

Carbon at red heat will remove oxygen from the oxides of the metals

A, B and C but not from the oxide of metal D. Metal C will remove

oxygen from the oxide of A but not from the oxide of B. Arrange the

metals A, B, C and D in a decreasing order of reactivity. Also give

reasons in support of your answer.

Answer 1

Answer:

• Since carbon removes oxygen from the oxides of metals A, B and C, therefore, carbon is more reactive than metals A, B and C.

• D is more reactive than carbon as carbon cannot remove oxygen from the oxide of D, i.e., D > carbon > A,B or C.

• Metal C is more reactive than metal A because it can remove oxygen from oxide of A, i.e., C > A.

• Since metal C cannot remove oxygen from the oxide of metal B, therefore, metal B is more reactive than C, i.e., B > C.

Thus the decreasing order of reactivity:

D > B > C > A.

Hope this helps!

Answer 2

Answer:

D>B>C>A is the decreasing order of reactivity
