A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
For the given unbalanced chemical equation:
[tex]C+SO_2\rightarrow CS_2+CO[/tex]
On the reactant side:
Atoms of C = 1
Atoms of S = 1
Atoms of O = 2
On the product side:
Atoms of C = 2
Atoms of S = 2
Atoms of O = 1
To balance the equation, one must balance the atoms by adding 2 infront of [tex]SO_2[/tex], 5 infront of [tex]C[/tex] and 4 infront of [tex]CO[/tex].
The balanced chemical equation becomes:
[tex]5C+2SO_2\rightarrow CS_2+4CO[/tex]
