Question

give one example of an oxidation reduction reaction which is also a combination reaction and displacement reaction​

Answer 1

(a)



Copper combines with oxygen to form copper oxide and it is also a oxidation-reduction reaction.

(b)



Here hydrogen displaces copper to form dihydrogen oxide(water)

Answer 2

(a)

♣2cu(copper) +O2(oxygen) heat>. --> 2Cuo ( copper oxide)

• Copper combines with oxygen to form copper oxide and it is also a oxidation-reduction reaction.

(b)

♣Cuo( copper oxide) + H2(Hydrogen) --heat----------->Cu( copper ) + H2o ( Water )

• Here hydrogen displaces copper to form dihydrogen oxide(water)
