There is carbon on only one side of the equation so we need to remove carbon from the products side so the equation is balanced.

4Fe₂O3 + 6 C   ------> 8Fe   + 6CO2
To balance the equation we added 6 Carbon (C) atoms on the reactants side since there are 6 in the products side but none on the reactants side .

H2 + Cl2 ----------> 2HCl

2H                         2H

2Cl                    2Cl

We have two H2 + Cl2, which produces HCl. and to balance the equation we have to add a coefficient of 2 to the HCl. At the end we would have two hydrogen atoms in the reactants and 2 in the products and two chlorine atoms in the reactants and two in the products.

O: 12                                O: 6 x 2 = 12
C: 6
It is incorrect since we didn't have carbon on the reactants side. So, in order to balance the equation we added 6 Carbon atoms to the reactants side. Thus, the correct equation will be:
4Fe₂O₃ + 6C --> 8Fe + 6CO₂
