Question

. What is meant by: (a) Displacement reaction (b) Reduction reaction (c) Combination reaction. Write

balanced chemical equation for each reaction​

Answer 1

Answer:

displacement reaction=

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.

Reduction reaction=

Reduction is the loss of oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised.

Combination reaction=

A combination reaction is a reaction in which two reactants combine to form one product.
