aluminium to gold

21
Q

what metals don’t react when heated in steam?

A

tin to gold

22
Q

why does aluminium act like its nonreactive?

A

it has a thin layer of oxide that acts like a barrier

23
Q

what is oxidation?

A

the gain of oxygen and loss of electrons

24
Q

what is reduction?

A

the loss of oxygen and gain of electrons

25
Q

what does the oxidising agent do?

A

provides oxygen and gets reduced

26
Q

what does the reducing agent do?

A

gets oxidised

27
Q

what does iron need to rust?

A

water and oxygen

28
Q

what speeds up the iron’s rusting?

A

salt

29
Q

why does boiled water prevent rusting?

A

there’s no oxygen in boiled water

30
Q

why does oil and paint prevent rusting?

A

they stop oxygen from entering

31
Q

why does cobalt chloride prevent rusting?

A

it dries out the air

32
Q

what methods prevent rusting?

A

painting, oiling and galvanising

33
Q

what is galvanising?

A

zinc acts as a sacrificial metal by preventing air and water from reaching the iron/steel

34
Q

how does oil and paint prevent rusting?

A

they act as a barrier for air and water

35
Q

where is carbon in the reactivity series?

A

between aluminium and zinc
