Chemistry 1 AQA

HideShow resource information
What are some ways of predicting earthquakes and volcanic eruptions?
Markers placed along plate boundaries checked for movement, monitoring volcano slope angles, rocks heating up before earthquakes
1 of 8
What are the conditions for solidifying oils?
Hydrogenated- reacted with hydrogen gas, a nickel catalyst and at about 60 degrees celcius
2 of 8
Are alkenes saturated or unsaturated?
Alkenes are unsaturated
3 of 8
What is the name of the copper ore?
Chalcocite
4 of 8
What are the properties of Titanium>
High melting point, protective oxide layer, denser than aluminium but less dense than most metals, strong
5 of 8
What are the properties of Aluminium?
Low density, excellent conductor, ductile, doesn't corrode due to oxide layer, not particularly strong but is used for alloys
6 of 8
How is aluminium extracted?
Aluminium is extracted using electrolysis (because it is fairly reactive and cannot be displaced by carbon) , with an electric current passed through molten aluminium oxide. Very expensive.
7 of 8
How is titanium extracted?
As extraction using carbon would make titanium very brittle, it has to be displaced by a more reactive metal such as sodium or magnesium, both of which have to be extracted by electrolysis beforehand.
