Ionization tendency problem

(1/1)

cloudy1290:
There are three metals A, B, and C. Read a) and b) , and arrange A, B, and C in order of decreasing ionization tendency.

a) A dissolves in dilute nitric acid, but B does not.
b) C reacts with water at room temperature, but A and B do not.

I don't have any idea how to do it. Please give me some hints and I will try to solve them again.

What is the reaction when a metal dissolves in/reacts with water or acid?

metal reacts with water and give H2 and metal hydroxide

metal reacts with acid and give H2 and salt

am i correct?

mjc123:
Yes. So what happens to the metal?

kahynickel:
Recall your concept when you say metal REACTs ..What is the meaning of the Word reactivity in the context of a metal ??
