Q

What process separates Liquids that have different boiling Points

A

Fractional distillation

17
Q

Describe the Fractional distillation (separates Liquids that have different boiling Points) process

A

The liquid with the lowest boiling point will boil first, be condensed and then collected

18
Q

What apparatus can be used for Fractional distillation

A 
Bunsen burner
Round bottom flask
Fractionating Column
Thermometer
Condenser
19
Q

Process to split up ionic compounds using electricity

A

Electrolysis

20
Q

What state does a compound need to be in for Electrolysis

A

either molten (melted) or in an aqueous solution (dissolved in water).

21
Q

Describe how Electrolysis process works

A

An Anode and Cathode are placed into a solution. The positive ions are attracted to the negative electrode (Anode) and vice versa.

22
Q

Why can Copper can be extracted using carbon

A

Copper is below carbon in the reactivity series (most reactive element is placed at the top and the least reactive element at the bottom)

23
Q

Describe how copper is extracted from ore

A

heat the compound containing copper(normally copper oxide) in powdered carbon.

24
Q

Name some uses of copper

A

Electronics
Wiring
Plumbing
