reactivity of metals

Question 1

name the reactivity series

Answer 1

insert picture of the reactivity series

Question 2

when does a displacement reaction occurs

Answer 2

occurs when a MORE reactive metal displaces (‘kicks out’) a LESS reactive metal from a compound.

Question 3

what happens to hydrogen when it reacts with a group 1 metal

Answer 3

group 1 is more reactive and displaces it and produces hydrogen gas and metal hydroxide

Question 4

what can we do with displacement reactions

Answer 4

We can use displacement reactions to obtain metals from their ores, by displacing with a more reactive. less valuable metal or carbon (‘coke’). This happens in a blase furnace: the iron oxide is ‘reduced’ (opposite Of oxidised) produce iron.
