Flashcards in C1.2 Rocks and Building Materials Deck (17):
1

State an environmental impact of producing mortar

It is produced from quicklime. Quicklime is produced in a rotary kiln which produces CO2 gas and contributes to global warming.

2

Chemical Name for Limestone

Calcium Carbonate

3

Formula for Limewater

Ca(OH)2(aq)

4

Equation for thermal decomposition of magnesium carbonate

MgCO3(s) --> MgO(s) + CO2(g)

5

Equation for thermal decomposition of calcium carbonate

CaCO3(s) --> CaO(s) + CO2(g)

6

Chemical name for quicklime

Calcium Oxide

7

Equation for reaction of calcium oxide with water

CaO(s) + H2O(l) --> Ca(OH)2(aq)

8

Formula for Slaked Lime

Ca(OH)2(aq)

9

Equation for reaction of calcium carbonate with hydrochloric acid

CaCO3(s) + HCl(aq) --> CaCl2(aq) + CO2(g) + H2O(l)

10

Name the salt produced when lime stone reacts with sulphuric acid in acid rain

Calcium sulphate (CaSO4)

11

Equation for reaction of lime water with carbon dioxide

Ca(OH)2(aq) + CO2(g) --> CaCO3(s) + H2O(l)

12

Formula for Calcium Oxide

CaO

13

Equation for thermal decomposition of Copper Carbonate

CuCO3(s) --> CuO(s) + CO2(g)

14

Chemical name for slaked lime

Calcium Hydroxide (solid)

15

Name one environmental impact of CO2

Global warming/effects oceans

16

Test for carbon dioxide

Lime water turns cloudy/white precipitate 

17

Chemical Formula for Calcium Carbonate

CaCO3
