Question

27. From the equations given below, identify the type of
chemical reaction and explain.(2 marks)
a) CuSO4 + Fe = FeSO4 + Cu
b) C+02 = CO2​

Answer 1

Answer:

(a)CuSo4+Fe=FeSo4+Cu

=Displacement reaction

(b)C+O2=CO2

=Combination reaction

Answer 2

Answer:

a) single displacement reaction

--> fe is more reactive than cu .so it displaced cu from its salt solution & formed feso4.

b) combination reaction

-->when two or more reactants combine together to form 1 single product then itis called combination reaction.

here, C and O2 combine together to form co2
