C1P1/1.Give ads about limestone quarrying
-provides jobs,large demand for it = lots of money
1 of 25
C1P1/2. Give disads about limestone quarrying
-noise, pollution, ugly, trasnposrting rocks from quarries=traffic & fossil fuels, take up land
2 of 25
C1P1/3. State the limecycle
CaCo3+heat=CaO + H2O=CA[OH]2+MORE H2O=CA[OH]2+CO2=CaCO3
3 of 25
C1P1/4.How do companies have to extract copper now?
-From low grade ores that contain little copper
4 of 25
C1P1/5.What are benefits of this?
-As there is a large demand for copper, profits are still made
5 of 25
C1P1/6.What are the disad?
-Extracting copper this was produces large amount of waste product which damages the environment
6 of 25
C1P1/7.What are 2 ways you can extract copper from low grade ores?
Phytomining and Bioleaching
7 of 25
C1P1/8.What is phytomining?
-Involves planting certain plants on low-grade copper ores. -Plant absorb copper compounds -Burning the plants produces ash that is rich in copper compounds
8 of 25
C1P1/9.What happens in electrolysis? [basic]
The negative electrode is made of pure copper. Impure copper forms the positive electrode. During electrolysis, positive copper ions move to the negative electrode. Waste material forms to the bottom

C1P1/10.What is in crude oil?
-Crude oil contains many different hydrocarbons therefore it is a mixture
10 of 25
C1P1/11.What are hyrdrocarbons?
-They are compounds made up of hydrogen and carbon only
11 of 25
C1P1/12.How can the hydrocarbons in crude oil be extracted?
By using fractions [fractional distilation]
12 of 25
C1P1/13.What is a fraction?
-A fraction is a mixture of hydrocarbons with similar numbers of carbon and similar boiling points
13 of 25
C1P1/14.List the method of fractional distillation
-Crude oil is heated to about 450C and then it evaporates being turned into a gas.-The gas enters the fractioning column and rises up. -As it rises, different fractions condense to form liquids again at different levels-Larger molecule&viscous= >temp

C1P1/15.What are alkanes? What does this mean?
Alkanes are saturated hydrocarbons therfore their carbon atoms are joined together by single covalent bonds
15 of 25
C1P1/16.What is the general formula for alkanes?
16 of 25
C1P1/17.What is the formula for: Methane and Ethane?
CH4 and C2H6
17 of 25
C1P1/18.How is CO2 and sulfur dixoide dangerous?
C02- Is greenhouse gas so increases global warmin and climate change -Sulfur dixiode produces acid rain
18 of 25
C1P1/19. What does global warming cause?
Climate change and melting of polar ice caps
19 of 25
C1P1/20. Acid rain has many environmental impacts. What are they?
-Makes lakes more acidic -Acid rain dissolves soil nutrients -Damages limestone buildings
20 of 25
C1P1/21. Why is Carbon monoxide dangerous?
It is invisible, poisonous, toxic
21 of 25
C1P1/22.How is Carbon monoxide produced?
If too little air is being supplied, incomplete combustion happens.
22 of 25
C1P1/23. What is incomplete combustion?
-Poor supply of O2-Carbon monoxide, water and carbon is produced
23 of 25
C1P1/24. Whats is complete combustion?
-Good supply of O2 -CO2 and H2O is produced
24 of 25
C1P1/25. What is carbon neutral?
Describes a fuel that absorbs as much as carbon dioxide when it is made as it gives out when it burns
