    Branches of Chemistry

    • Inorganic chemistry focuses on compounds that do not primarily contain carbon, including minerals and salts.
    • Organic chemistry studies carbon-containing compounds, primarily hydrocarbons and their derivatives, which form the basis of life.
    • Physical chemistry combines principles of physics with chemistry, examining how matter behaves and its energy changes at the molecular and atomic levels.
    • Analytical chemistry involves methods and techniques to determine the composition and concentration of substances, enabling identification and quantification.
    • Biochemistry explores the chemical processes and substances that occur within living organisms, bridging biology and chemistry.

    Chemical Bonding

    • Atomic orbitals describe regions surrounding an atom where the probability of finding electrons is highest.
    • Molecular orbitals represent areas around a molecule where electrons can be found, resulting from the combination of atomic orbitals.
    • A chemical bond is the attractive force that holds atoms together in a molecule, enabling the formation of compounds.
    • Ionic bonds involve the transfer of electrons from one atom to another, resulting in charged ions that attract each other.
    • Covalent bonds occur when atoms share pairs of electrons, forming strong connections within molecules.
    • Hydrogen bonds are weaker electrostatic attractions that can occur between molecules, playing a crucial role in the structure of water and biological macromolecules.

    Chemical Reactions

    • A chemical equation serves as a symbolic representation of a chemical reaction, using formulas and symbols to depict the involved substances.
    • Reactants are the starting materials that undergo transformation during a chemical reaction, while products are the new substances formed.
    • Synthesis reactions involve combining two or more reactants to produce a single new compound, a fundamental type of chemical reaction.
    • Decomposition reactions feature the breakdown of a single reactant into two or more products, reversing synthesis processes.
    • Replacement reactions occur when one element or group is exchanged for another in a compound, often seen in single or double replacement formats.

    Stoichiometry

    • The mole is a fundamental unit in chemistry used to quantify the amount of substance, defined as containing approximately 6.022 x 10²³ particles.
    • Molar mass is the mass of one mole of a substance, typically expressed in grams per mole, critical for stoichiometric calculations.
    • The empirical formula provides the simplest integer ratio of elements in a compound, reflecting its basic composition.
    • The molecular formula offers precise information on the actual number of each type of atom present in a molecule, which can be a multiple of the empirical formula.

    Laboratory Techniques

    • Chromatography is a method for separating components in a mixture based on differing physical or chemical properties, widely used in analytical chemistry.
    • Spectroscopy involves studying how matter interacts with electromagnetic radiation, allowing for the identification of substances based on their spectral patterns.
    • Titration is a quantitative analytical technique used to determine the concentration of a solution by reacting it with a solution of known concentration, often involving an indicator that signals the end of the reaction.
