1. Word Equations
Fill in the gaps in these word equations to make them complete. If there is no reaction write this in the gap.
Sodium + water Sodium hydroxide +
Magnesium + oxygen
Iron + water (steam) oxide + hydrogen
Silver + water (steam)
+ Hydrochloric acid Calcium chloride + hydrogen
Sodium + Sulphuric acid hydrogen
Copper chloride + Magnesium copper
Calcium + oxygen
Silver nitrate + Iron
Gold + oxygen
Iron sulphate + Copper
+ Nitric acid Zinc nitrate +
Potassium hydroxide + hydrogen
Magnesium carbonate + Iron
Magnesium Chloride + Zinc

2. Displacement Reactions
A more reactive metal displaces a less reactive metal from its compounds.
There are many ways to help you remember how displacement reactions work.
Model 1
The metals football league:
Potassium Rangers
Sodium City
Magnesium United
Zinc City
Iron Town
Copper United
Gold United
The league works like this: The teams play for a cup (the Chloride Cup). The team at home is always the cup holder. If the away team beats them then they take home the cup, if the home team wins then they keep the cup.
The metals nearer the top are stronger teams and they always beat the teams that are lower than them.
Example:
Home Away Winners Losers
Zinc City Sodium City Sodium City Zinc City
Chloride cup Chloride Cup
Reaction:
Zinc Chloride Sodium Sodium Chloride + Zinc
Model 2
Another way is to think of the metals in the reactivity series as boys of varying strength. The strength (and temper) of the boys increases as you go up the table. + +
Colin Copper and Suzie Sulphate.
Peter Potassium is stronger than Colin Copper so fights him……………
……and takes Suzy sulphate away.
Colin Copper is all alone.
Reaction:
Copper Sulphate Potassium Potassium Sulphate Copper
