What happens to metal carbonate when heated?
It decomposes to produce metal oxide and carbon dioxide
7 of 19
What happens when Carbonates react with Acid?
they produce salt, water and carbon dioxie
8 of 19
What is Limestone damaged by?
Acid rain
9 of 19
How do we test for Carbon dioxide?
Limewater- it will turn cloudy
10 of 19
Whats the first step of the limestone reaction cycle?
Thermal decomposition of Calcium carbonate (CaCO3) produces calcium oxide and carbon dioxide
11 of 19
What is the balanced symbol equation for the first step of the reaction cycle?
CaCO3 ----> CaO + CO2

What is the second step of the limestone reaction cycle?
Calcium Oxide reacts with water to make Calcium Hydroxide
13 of 19
Whats the symbol for Calcium Hydroxide?
Ca(OH)2
