Chemistry

Calculate Kp from equilibrium pressures or from Kc, temperature, and delta n with clear setup checks and expression help.

Calculate Kc or Kp from equilibrium concentrations or partial pressures and check the expression, exponents, and phase omissions.

Balance chemical equations with smallest whole-number coefficients and check atom counts for each element side by side.

Calculate rate constants, activation energy, A, temperature, or a new-temperature rate with unit-safe Arrhenius formulas.

Find actual yield, theoretical yield, or percent yield with gram-to-mole conversion and clear mixed-unit checks.

Find activation energy from Arrhenius data using k, A, and temperature or two temperatures and two rate constants.

Calculate total water hardness in mg/L as CaCO3 and grains per gallon from a report reading or calcium and magnesium values.

Find an unknown titrant or analyte concentration or volume at equivalence using molarity, mL, and reaction parts.

Convert conductivity, TDS, ppm, and mg/L with a chosen meter factor and quick drinking-water context.

Calculate a missing dilution value, stock volume, diluent difference, final volume, or dilution factor from your solution values.
