How many types of chemical reactions are there explain with examples?
Answers
Answer:
(1)combination reaction=if 2 or more reactants reacts to form a single product
eg=c + o2 co2
(2) decomposition reaction=if a single reactants to break down to form 2 or more products.
it is of
(a)thermal decomposition
eg=Ag + Br =Agbr
(b)photolytic decomposition
eg=caco3=heat+cao + co2
(c) electrolytic decomposition
H2 +o2 =H2O
(3) displacement reaction
a high reactive metal displace a low reactive metal from its salt solution
eg= cu + feso4=cuso4 + fe
(4)double diaplacement
Explanation:
There are 4 types of chemical reactions.
1)combination reaction___
It is the reaction in which two or more reactants reacts to form single product
Eg. 2mg+O2 gives 2Mg
2)decomposition reaction___
It is a reaction in which single reactant breaks to form two or more products
Eg. 2H2O gives 2H2 + O2
3) DISPLACEMENT REACTION
the reaction in which more reactive metal displaces the less reactive metal.
Eg. CuSo4+fe gives FeSo4 +cu
4)DOUBLE DISPLACEMT REACTION.
the reaction in which exchange of ions occur.
Eg. NaCl2 +BaSo4 gives Bacl2 +NaSo4
