Hydrogen in the reactivity series

Air with carbon or copper

1

Reactivity series.

This is quite a tricky question.

Remember:

a) metals below hydrogen will not react with acids
e.g copper + acid = no reaction

b) metal oxides of metals below carbon will react with carbon.

Iron oxide + carbon -> iron + carbon dioxide

c) metal oxides of metals above carbon will not react with carbon.

Aluminium oxide + carbon = no reaction.

Reactions of acids.

Hint. a base is a metal oxide or metal hydroxide
