What is limestone mainly made of? CHemical and word symbol,
Calcium Carbonate, CaCO3
1 of 16
What is the reaction called when calcium carbonate is broken down by heat?
Thermal decompositon,
2 of 16
When Calcium Carbonate is decomposed, what are the two products? Chemical and word?
Calcium Oxide, CaO + Carbon dioxide, CO2
3 of 16
Give an example of another carbonate which works in the same way?
Cooper carbonate, Sodium carbonate, magnesium carbonate,
4 of 16
If metals are high up in the reactivity series and are carbonates, what do they need to decompose?
Lots of energy,
5 of 16
What colour is calcium oxide when hot and cold?
Hot-yellow, Cold-white,
6 of 16
What is the symbol for calcium hydroxide?
Ca(OH)2
7 of 16
How is calcium hydroxide produced? Word and chemical?
CaO, Calcium oxide, + H2), Water,
8 of 16
What is the function of hydroxide and why is it able to do this?-Chemical property?
To neutralise excess acidity in lakes and soils affected by acid rain as it is an alkali,
9 of 16
When carbonates react with acids, what are produced?
Carbon dioxide, salt and water,
10 of 16
When calcium carbonate comes into contact with acid rain, waht can be seen?
They fizz when in contact and CO2 is released which can be detected with limewater,
11 of 16
How is cement made?
By heating powdered limestone with clay
12 of 16
How is mortar made and its job?
Used to join bricks together-made by mixing cement(clay + powdered limestone) with sand and water
13 of 16
How is concrete made?
By mixing cement (clay + powdered limestone) with sand, water and crushed rock,
14 of 16
What are the advantages of the limestone industry?
Limestone is a valuable natural material used to make lots of useful things like glass and concrete. -It provides employment from local towns in quarrying, -Provides leisure after quarrying, -Money goes to towns around quarry,
15 of 16
What are the disadvantages of the limestone industry?
-Quarries are visible from long distances and may damage the view and landscape, -Creates noise and dust pollution, -Creates heavy traffic which releases more CO2, -Destroyes animal habitats, -Damages people's quality of life, -Lots of dust,
