Reactive metals can displace less reactive metals from their compounds

Reactive metals can displace less reactive metals from their compounds in solution or molten form. All metals are not equally reactive. The reactivity of various metals with oxygen, water and acids. But all metals do not react with these reagents. So we were not able to put all the metal samples we had collected in decreasing order of their reactivity. Displacement reaction give better evidence about the reactivity of metals.1. State True or False :Metals are reactivea. TRUEb. FALSE2. Reactivity of metals are evidenced by .a. Displacementb. Replacement3. Do All metals reacts with reagent.a. YESb. NO4. Why can all metals not be put in increasing order?a. All Metals do react with reagentsb. All Metals do not react with reagents5. Metals react with _.a. Oxygenb. Waterc. Acidd. All of the above
