What happens when you heat Calcium Carbonate?
When heated, Calcium Carbonate glows orange and makes Calcium Oxide.
1 of 21
What is the common name for Calcium Oxide and the formula?
Quick lime - CaO (s)
2 of 21
What happens when you add water to Calcium Oxide?
It produces heat (fizzes) - Calcium hydroxide is produced.
3 of 21
What is the common name for Calcium Hydroxide and the formula?
Slacked lime - Ca(OH)2
4 of 21
What happens when you dissolve Calcium Hydroxide in water?
It makes Calcium Hydroxide solution.
5 of 21
What is the common for Calcium Hydroxide solution?
Lime water.
6 of 21
What is the formula for Calcium Hydroxide solution?
Ca(OH)2 (aq)
7 of 21
What happens if you bubble Carbon Dioxide into lime water?
The lime water turns cloudy.

What is limestone used for? (5 points)
Toothpaste/ Bread/ Concrete/ Neutralise acid soil/ Medicine/ Roads/ Cosmetics/ Glass/ Cement.
9 of 21
What are the problems caused by quarrying limestone?
Traffic in local village (Vans etc.)/ Most are around National Parks/ Explosions shake buildings/ Noise pollution/ Visual pollution.
10 of 21
Benefits of limestone?
Neutralises acid soil/ Carves well and lasts a long time/ Disused quarries filled with water can be used for boating and lakes.
11 of 21
What is thermal decomposition?
When something such as Calcium Carbonate breaks down due to high heat.
12 of 21
What is the thermal decomposition word equation for calcium carbonate?
Calcium Carbonate ---> Calcium Oxide + Carbon Dioxide
13 of 21
Which carbonate decomposes most easily? 1) Calcium carbonate. 2) Zinc carbonate. 3) Copper carbonate.
Copper carbonate.
14 of 21
Which carbonate decomposes least easily? 1) Calcium carbonate. 2) Zinc carbonate. 3) Copper carbonate.
Calcium carbonate.
15 of 21
Other than the production of CO2, how can you tell that zinc and copper carbonate decomposed when heated?
Colour change for both carbonates. Zinc: White ---> Yellow. Copper: Green---> Black.
16 of 21
Complete these equations: 1) CuCO3 ---> CuO + ___ . 2) ___ ---> ZnO + CO2
1) CO2. 2) ZnCO3.
17 of 21
Balance these equations: 1) ___Ca + O2 ---> ___CaO . 2) CaCO3 + ___ HCl ---> CaCl2 + H2O + CO2
1) 2Ca + O2 ---> 2CaO . 2) CaCO3 + 2HCl ---> CaCl2 + H2O + CO2 .
