Question

4) Name the substance oxidised and reduced in the following reaction:
a) 2PbO + C → 2Pb + CO2
b) ZnO + C-→ Zn + CO
c) 2H2S + SO2 → 3S + 2 H2O
​

Answer 1

a) pbo reduced to pb

c oxidised to co2

b) zno reduced to zn

c oxidized to co

c) H2s oxidised to H2o

so2 reduced to s

Answer 2

SALUT MATE!!

a) 2PbO + C → 2Pb + CO₂

• SUBSTANCE OXIDIZED : C
• SUBSTANCE REDUCED : PbO

b) ZnO + C → Zn + CO

• SUBSTANCE OXIDIZED : C

• SUBSTANCE REDUCED : ZnO

c) 2H₂S + SO₂ → 3S + 2H₂O

• SUBSTANCE OXIDIZED : H₂S

• SUBSTANCE REDUCED : SO₂
