reactivity series

Question 1

Metal reactions with water

Answer 1

metal + water —–> Metal hydroxide + oxygen

Some metals react with water to produce a metal hydroxide + hydrogen

Question 2

Metal reactions with acid

Answer 2

Metal + acid —–>salt + hydrogen

e. g. Potassium + hydrochloric acid
- —> potassium chloride + hydrogen

Some metals react with acid to produce a salt and hydrogen gas

Question 3

Displacement reactions replacement

Answer 3

This is when a more reactive element takes the place of a less reactive element in the compound

e.g. Iron Sulfate + Zinc—->
Zinc sulfate + Iron

Question 4

Displacement no reaction

Answer 4

A displacement no reaction is when the reaction doesnt happen because the less reactive element doesn’t take place over the more reactive element. Also when the same element reacts with each other there is no reaction because they have the same reactivity.

Question 5

Most reactive to least reactive
