What are the products of the thermal decomposition of Calcium Carbonate?
Calcium Oxide and Carbon Dioxide
1 of 8
How is concrete made?
Cement is mixed with sand, water and aggregate and a slow chemical reaction occurs
2 of 8
Why does acid rain dissolve limestone?
The acid reacts with calcium carbonate producing CO2 and a salt. The salt dissolves in water so the amount of limestone decreases
3 of 8
What is quicklime?
Calcium Oxide
4 of 8
What is reinforced concrete?
Concrete with steel rods to add extra support to a structure.
5 of 8
What is the symbol equation for the reaction between calcium hydroxide and carbon dioxide?
Ca(OH)2 + CO2 ---> CaCO3 + H2O
6 of 8
What is produced when you add water to calcium oxide?
Calcium Hydroxide
7 of 8
Why is calcium hydroxide spread on acidic fields?
Calcium Hydroxide is an alkali so it neutralises acids improving the pH of the soil for growing crops
