What is the basic unit of chemistry

The atom

How is stoichiometry used

Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.

What makes balancing redox reactions different from balancing other reactions

Balancing redox reactions is different from balancing other reactions because both the number of atoms and the amount of charge must be balanced.

Reduction occurs at the cathode in an electrolytic cell.

What needs to be considered in balancing redox reactions

Both atoms and charge
