Balance equations and solve stoichiometry

Balance equations, calculate yields, and predict redox half-reactions

Solving quantitative chemistry problems and thermochemistry without calculation errors.

• · Chemical equations, masses, mole counts, acid-base concentrations

• · Balanced equations, limiting reagent, percent yield, pH, Eo, enthalpy

• · Valence electron counting
• · Oxidation-state assignment

• · Unbalanced equations (mass not conserved)
• · Ignoring limiting reagent
• · pH calculations without Ka/Kb
