What is thermal decomposition?
It is the process by which calcium carbonate decomposes to produce calcium oxide plus carbon dioxide to using heat

Test for chlorine?
Hold a dump do you let this paper towards the mouth of the test-tube if drawing is present it will turn it red and white if bleached
2 of 14
Uses of chlorine?
Manufacturing plastics, manufacturing bleach, used in water supply to kill microorganisms
3 of 14
What happens in the reaction between calcium oxide and water?
When calcium oxide and what is reacted it produces calcium hydroxide which is the white crumbly precipitate and therefore when calcium hydroxide is then reacted with excess water it will produce calcium hydroxide solution (limewater)

Oxidation is… + reduction is…
The gaining of oxygen (but the removal of electrons C3) + The removal of oxygen (but the gaining of electrons C3)

How do you sulfer dioxide form?
For dioxide forms when sulphur impurities react with oxygen in the air this then dissolves in rain and forms acid rain which causes statues made of limestone to erode , If leaked into rivers and lakes it could cause a threat to wildlife.

how does iron seeding remove co2
Iron seeding- plants use iron nutrients for growth and repair therefore adding iron compiles means more plants can photosynthesis and be eaten= sea creatures die and shells buried remove CO2
7 of 14
How's does capturing co2 from waste gasses removes CO2
When co2 is captured from waste gases that burn fossil fuels they are reacted to produce hydrocarbons compounds such as propane which can be used for fuel.
8 of 14
Why is cracking need
Since there is more demand for shorter molecules and since they are more useful, it also produces unsaturated hydrocarbons which can be used as fuel and petrol
9 of 14
What makes a good fuel
How easily it burns, how easy it is to transport and store, how much ash and smoke it produces, how much heat(thermal energy it produces), how easy it burns, if it is easy to ignite
10 of 14
How are biofuels obtained
Biofuels are obtained from living organisms or organisms that have died.

What do antacids do and what do they contain?
Antacids can neutralise excess stomach acid and some contain bases which are substances that react with acids to produce salt +water
12 of 14
What are the uses of aluminium and explain
Aluminium is used in aircrafts since it has low desities which means that less fuel is needed to fly longer distances. Used in cans since it does not corrode since has a layer of Aluminium oxide
13 of 14
What are the uses of copper and why
Copper is used in electrical wiring and electrical conductors since it is ductile and malleable. Less reactive hence use in water pipes and resistant to corrosion replace lead since it reacted with water and caused lead poisoning

one of them is supposed to be hold a damp blue litmus paper and it will turn read if chlorine is present and will turned white if bleached
