Question

Define the following reactions giving example of each-
A)Combustion reaction
B) Displacement reaction
C)Double Displacement Reaction
D)Redox reaction
E) Neutralisation reaction

​

Answer 1

combustion reaction

$2Mg + O_2 = 2MgO$

$Zn + H_2SO_4 = ZnSO_4 + H_2$

$Na_2SO_4 + BaCl_2 = BaSO_4 + 2NaCl$

$CuO + H_2 ==Heat==> Cu + H_2O$

$Na_2CO_3 + 2HCl = 2NaCl + H_2O + CO_2$

Answer 2

B)The reaction in which a place of a weak element is taken by a strong element is called as Displacement reaction.

C)The reaction in which the elements gets exchanged in their product is called as Double Displacement reaction
