Oxidizing agent Are being reduced because they accept
electrons
Reducing agents Are being oxidized because they donate
electrons
Reduction The process of gaining electrons
Electrolyte A substance that dissociates into ions in solution

solubility
Mixture A combination of two or more substances that
retain their individual properties
Molar mass of Na The mass of one mole of sodium, approximately
22.99 g/mol
How is energy transferred? potential and kinetic energy, heat and work
, Oxidation gain of protons, increase in oxidation number,
energy of motion, loss of electrons
What is a product? A substance produced in a chemical reaction

What is dilution? the addition of a solvent to decrease the
concentration of a solute in a solution
What is a decomposition reaction? When a single compound is broken down into
smaller molecules (AB→A+B)
What is reduction? loss of oxygen or gain of electrons
What is a homogeneous mixture? a mixture that has a uniform composition
throughout
