Question

examples of doubledisplacement reactions
example of displacement 2 (examples)
example of decomposition 2(examples)

Answer 1

Example for displacement reaction: Barium chloride and sodium sulphate react to form barium sulphate(white precipitate) and sodium chloride

Example for displacement reaction: Iron filings react with copper sulphate to form iron sulphate + copper and chlorine and sodium bromide react to form chlorine bromide and sodium

Example for decomposition reaction: (1) The decomposition of carbonic acid in soft drinks, which can be represented by the chemical equation H2CO3 → H2O + CO2
(2)The electrolysis of water to yield hydrogen and oxygen.
