Define an ore and give some examples. (4)
Ores are naturally occurring rocks that contain metals or metal compounds in sufficient amounts to make it worthwhile extracting them. (1)
Iron ore (1)
Magnetite (1)
Platinum (1)
How metals are extracted from their ores using different
methods depending on their place on the reactivity
series.
Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, (1)
While metals less reactive than carbon, such as iron, may be extracted by reduction with carbon. (1)
As gold is so unreactive, it is found as the native metal and not as a compound. It does not need to be chemically separated. (1)
Thermal Decomposition. (1)
Thermal decomposition is a chemical reaction that happens when a compound breaks down when heated.. (1)
Reactions of Metals with, oxygen, water and acid.
Water
When a metal reacts with water, a metal hydroxide and hydrogen are formed. (1)
Oxygen
Many metals react with oxygen to form metal oxides. (1)
Acids
Acids react with most metals. · When an acid reacts with a metal, the products are a salt and hydrogen. (1)
EXAMPLES on PPT pg 39, 40, 42
What is the test for Oxygen?
Oxygen supports combustion. If oxygen is present in a test tube, a glowing splint relights when it is held inside. (1)
Displacement reactions and how to write out the relevant
word equations.
In displacement reactions a more reactive metal will displace a less reactive metal from its compound. (1)
Iron + copper sulfate → copper + iron sulfate. (1)
