Question 14

Very reactive metals like ____________ will all react vigorously with water

Answer 14

(One of potassium, sodium, lithium, calcium, francium)

Question 15

Less reactive metals like ____________ won’t react with water but they will react with ___________

Answer 15

(One of Magnesium, Zinc, Iron)

Steam

Question 16

__________ won’t react with either water or steam

Answer 16

Copper

Question 17

Reactivity series:

Answer 17

Potassium
Sodium
Lithium
Calcium
Magnesium
Aluminium
Zinc
Iron
Copper
Silver
Gold

Question 18

A ________ reactive metal will displace a ________ reactive metal

Answer 18

More

Less

Question 19

Why will a more reactive metal displace a less reactive metal from its oxide

Answer 19

Because it will bond more strongly to the oxygen

Question 20

Iron oxide + Aluminium —>

Answer 20

Iron oxide + Aluminium —> Aluminium oxide + iron

Question 21

Metal compounds such as, copper sulfate, zinc chloride and sodium chloride are all metal ________

Answer 21

Metal salts

Question 22

What happens if you put a reactive metal into a solution of a less reactive metal salt

Answer 22

The reactive metal will replace the less reactive metal in the salt
E.g. Copper sulfate + Iron —> Iron sulfate + Copper

Question 23

If you put a less reactive metal into a solution of a more reactive metal salt, what will happen

Answer 23

Nothing. No displacement

Question 24

How are displacement reactions useful in chemistry

Answer 24

They allow for you to figure out where in the reactivity series a metal is supposed to go
