Question 2

copper sulphate + zinc ——->

Answer 2

zinc sulphate + copper

Question 3

what is the reactivity order

Answer 3

potassium, sodium, calcium, magnesium, alminium, carbon, zinc, iron, tin, lead, hydrogen, copper, silver, gold, platinum

Question 4

aluminium is a reactive metal found near the top of the reactivity series, name the method used in this extraction

Answer 4

displacement

Question 5

gold and magnesium sulphate

will this react and why

Answer 5

no because magnesium is more reactive than gold

Question 6

what does oxidized mean

Answer 6

when a metal chemically bonds with oxygen.

Question 7
