#1
Front (Question)

What is the reactivity series?

Back (Answer)

A list of elements ordered by their reactivity

#2
Front (Question)

How can metals be placed in order of their reactivity?

Back (Answer)

Add the metals to water or acid and see which ones react the most (by how much fizzing there is)

#3
Front (Question)

What is the name for a reaction where oxygen is removed from a compound?

Back (Answer)

Reduction

#4
Front (Question)

Explain why zinc can be extracted from zinc oxide with carbon but magnesium cannot be extracted from magnesium oxide with carbon

Back (Answer)

Magnesium is more reactive than carbon (1), Zinc is less reactive than carbon (1), Carbon can therefore remove oxygen from zinc oxide but not magnesium oxide (1)

#5
Front (Question)

Explain why gold and silver can be found naturally in the Earth’s crust

Back (Answer)

It is very unreactive

#6
Front (Question)

What process is used to extract metals more reactive than carbon

Back (Answer)

Electrolysis

#7
Front (Question)

Define an ore

Back (Answer)

A material containing enough metal in it for it to be economically worthwhile to extract the metal.

#8
Front (Question)

Define a displacement reaction

Back (Answer)

A reaction in which a more reactive element takes the place of a less reactive element in one of its compounds or in solution

#9
Front (Question)

Define oxidation in the context of loss and gain of electrons

Back (Answer)

Oxidation is the loss of electrons

#10
Front (Question)

Define reduction in the context of loss and gain of electrons

Back (Answer)

Reduction is the gain of electrons

#11
Front (Question)

Which of the substances below has been oxidized and which has been reduced? Al3+ + Fe gives Fe3+ + Al

Back (Answer)

Aluminium has been reduced and iron has been oxidised

#12
Front (Question)

Show two half equations for the reaction below: Al3+ + Fe gives Fe3+ + Al

Back (Answer)

Al3+ + 3e- gives Al , Fe gives Fe3+ + 3e-
