What is something if it is oxidised
It has been through oxidation and has gained oxygen
How can metal oxides be reduced
by Reducing oxygen
When a metal is very reactive what did it usually do more easily than other metals
Lose electrons
What do metals react with is to place them in order of reactivity
Acid and water
What do metals react with acids to produce
Metal salts and hydrogen
Lithium sodium and potassium are very reactive metals they’re reactor vigorously with water to produce_____

Not necessarily very active but fairly reactive metals metals for example calcium magnesium zinc and iron react quickly with ____ and slowly with _____
Acid and water
What happened in a displacement reaction
A more reactive metal will displace a less reactive metal from a solution of its salt
If magnesium and copper sulphate reacted what would it produce
