<span>Answer:
Nothing is balanced in your final equation: not H, not O, not Cr, not I and your charges aren't either.
Start with your 2 half reactions:
I- --> IO3-
Cr2O72- --> 2 Cr3+
Balance O by adding H2O:
I- + 3 H2O --> IO3-
Cr2O72- --> 2 Cr3+ + 7H2O
Balance H by adding H+:
I- + 3 H2O --> IO3- + 6 H+
Cr2O72- + 14 H+ --> 2 Cr3+ + 7H2O
Balance charge by adding e-:
I- + 3 H2O --> IO3- + 6 H+ + 6 e-
Cr2O72- + 14 H+ + 6 e- --> 2 Cr3+ + 7H2O
Since the numbers of electrons in your two half reactions are the same, just add them and simplify to give:
Cr2O72- + I- + 8 H+ --> IO3- + 2 Cr3+ + 4 H2O</span>

A conductor is distinguished from an insulator with the same number of atoms by the number of nearly free electrons.
<h3>What are conductors and insulators?</h3>
Whether an object is made of conductive or nonconductive material affects how it behaves once it has been charged. Electrons can move freely between particles when they are in conductors, which are substances. The charge can be transported across the whole surface of an object constructed of a conducting substance.
A charge is swiftly dispersed across the full surface of the object if it is applied to it at a specific point. The motion of the electrons causes the distribution of charge. A charged object will constantly disperse its charge until the overall repulsive interactions between surplus electrons are minimized because conductors allow electrons to be moved from particle to particle.
Insulators, as opposed to conductors, are substances that prevent electrons from freely moving from one atom or molecule to another.
