Cross out the words in bold that are wrong:
Magnesium is the most reactive metal that we used. It
did/did not react with solutions of the salts of zinc, iron
and copper. Copper is the least reactive metal that we
used. It did/did not react with solutions of the salts of
magnesium, zinc and iron. Metals react with the salts of
metals that are more/less reactive than they are.
