Question

How can you see that oxygen has been removed in the chemical equation?

2Pb + C → 2Pb + C$O_{2}$

Answer 1

Answer:

Correct Chemical Equation:-

$\sf2PbO + C → 2Pb + CO_2$

This reaction is a redox reaction where PbO is Lead (II) Oxide that is reduced to Lead (Pb) and Carbon or C is oxidized to CO2 or Carbon dioxide.

Answer 2

Answer:

2PbO+C→2Pb+CO2

This reaction is a redox reaction where PbO is Lead (II) Oxide that is reduced to Lead (Pb) and Carbon or C is oxidized to CO2 or Carbon dioxide.
