Answer 1

Answer :

Sorry to say but, Your options are not correct.

The correct answer is (I) and (ii) are balanced.

(iii) and (iv) are wrong.

(iii) When 2Pbo + C are added together, then it forms 2 Pb + CO2. ( not Pb + CO2) .

(iv) When Fe2O3 + 2Al are added together, then it forms Al203 + 2Fe.

( not Al2CO3 + 2Fe )
