Reaction of metals with oxygen, water, acids, with solution of other metal salts
Answers
Answer:
Chemical reactions involving oxygen are known as oxidation reactions.
Corrosion and combustion are two examples of oxidation reactions.
Corrosion reactions are generally very slow, whereas combustion reactions are very fast and produce large amounts of heat and light.
Metals can undergo both corrosion and combustion reactions, depending on the type of metal and the reaction conditions.
* Corrosion reactions are specific to metals, but don’t always involve oxygen; they may also involve other oxidants, such as sulfur.
* Combustion reactions are not specific to metals – they may involve a wide variety of fuels, usually carbon compounds.
iron + oxygen → iron (III) oxide
4 Fe (s) + 3 O2 (g) → 2 Fe2O3 (s)
The corrosion of iron is known as rusting.
zinc + hydrochloric acid → zinc chloride + hydrogen
Zn (s) + 2 HCl (aq) → ZnCl2 (aq) + H2 (g)
Mixing calcium and iron (II) nitrate will result in a chemical reaction as calcium is more reactive than iron:
calcium + iron (II) nitrate → calcium nitrate + iron
Ca + Fe(NO3)2 → Ca(NO3)2 + Fe
Mixing copper and iron (II) nitrate will not result in a chemical reaction as copper is less reactive than iron:
copper + iron (II) nitrate → no reaction
Cu + Fe(NO3)2 → no reaction

Answer:
How do Metals react with Solutions of other Metal Salts? When more reactive metal react with solution of less reactive metal salt, more reactive metal displace less reactive metal from its salt. ... Such reaction is known as displacement reaction or single displacement reaction.
