Limestone Chemistry

Front 1

Uses of Calcium Carbonate

Back 1

Building materials, cement, neutralising soils
CaCO3

Front 2

Quarrying Limestone Advantages

Back 2

Raw materials, jobs, money, hole used as lake

Front 3

Quarrying Limestone Disadvantages

Back 3

Noise and dust pollution, destroys habitats if it's a new hole, more traffic and carbon emmissions

Front 4

Thermal Decomposition

Back 4

Adding heat to break down material

Front 5

Metal carbonate =

Back 5

Metal oxide + carbon dioxide

Front 6

Test for CO2

Back 6

Bubbles through limewater, turns it milky

Front 7

Uses of Limestone

Back 7

Cement - limestone and clay
Concrete - cement, sand, gravel and water: Strong and crush resistant
Mortar - sand, cement + water
Amount of sand affects strength
Amount of water affects hardening

Front 8

Limestone Cycle

Back 8

1: Thermal decomposition of Calcium carbonate = CaO + CO2
2: Few drops of water - CaO + H2O = Ca(OH)2 (solid)
3: More water and filter: Ca(OH)2 + H2O = Ca(OH)2 (aq.)
4: Add CO2: Ca(OH)2 + CO2 = CaCO3 + H20
