Question

Q.18 Read the following paragraph and answer the following
questions:
Redox reactions are those reactions in which oxidation and
reduction occur simultaneously. A redox reaction is made up of
two half reactions. In the first half reaction ,oxidation takes
place and second half reduction occurs. Oxidation is a process in
which a substance loses electrons and in reduction substance
gains electrons. The substance which gains electrons is reduced
and acts as an oxidizing agent. On the other hand, a substance
which loses electrons is oxidized and acts as a reducing agent.
1. Which of the following is a redox reaction?
aCaCO3------à CaO+CO2
b.H2 + C12 ------à 2HCI
cCa0+ 2HCl ------à CaCl2 + H2O
2. For the following reactions, identify the correct statement
ZnO + CO ---------à Zn + CO2
a.ZnO is being reduced
b.CO2 is being oxidized
c.ZnO is being oxidized
