Important Equations and Formulas

In order to succeed on your Chem 101 final exam, it’s crucial to have a solid understanding of important equations and formulas. These mathematical expressions will help you solve various problems and calculations in chemistry.

Gas Laws:

The ideal gas law: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.
Boyle’s Law: P1V1 = P2V2, which shows the inverse relationship between pressure and volume when temperature remains constant.
Charles’ Law: V1/T1 = V2/T2, demonstrating the direct relationship between volume and temperature, assuming pressure remains constant.
Avogadro’s Law: V1/n1 = V2/n2, indicating the direct relationship between volume and the number of moles when pressure and temperature are constant.

Stoichiometry:

Mole ratio: A balanced chemical equation allows you to determine the ratio of moles between the reactants and products.
Percent yield: (actual yield / theoretical yield) × 100%, used to calculate the efficiency of a chemical reaction.
Limiting reactant: The reactant that is completely consumed and determines the amount of product that can be formed.
Molarity: Molarity (M) is calculated by dividing the number of moles of solute by the volume of the solution in liters. M = moles of solute / liters of solution.

Acids and Bases:

pH: The negative logarithm of the hydrogen ion concentration, measured on a scale from 0 to 14. pH = -log[H+]
pOH: The negative logarithm of the hydroxide ion concentration. pOH = -log[OH-]
pKa: The negative logarithm of the acid dissociation constant (Ka). pKa = -log(Ka)
Buffer solutions: Composed of a weak acid and its conjugate base or a weak base and its conjugate acid, they resist changes in pH.

Thermodynamics:

Enthalpy change (ΔH): The heat energy exchanged during a chemical reaction.
Gibbs free energy (ΔG): Determining if a reaction is spontaneous or non-spontaneous. ΔG = ΔH – TΔS, where T is temperature and ΔS is entropy change.
Entropy (ΔS): The measure of disorder or randomness in a system.
Heat capacity (C): The amount of heat energy required to change the temperature of a substance by 1 degree Celsius.

These equations and formulas provide the foundation for understanding and solving problems in chemistry. Make sure to practice using them in different contexts to solidify your knowledge before the final exam.
