    Study Notes

    Properties of Matter

    • Matter is anything that has mass and occupies space, existing in solid, liquid, or gas states.
    • Can be naturally occurring or synthetic, capable of changing forms through various processes.

    Classification of Matter

    • Divided into pure substances and mixtures.
    • Pure Substances: Fixed composition, properties do not change.
      • Elements: Consist of identical atoms, found on the periodic table (e.g., hydrogen, oxygen).
      • Compounds: Composed of two or more elements in fixed mass ratios (e.g., water H2O, carbon dioxide CO2).

    Mixtures

    • A combination of two or more pure substances, which can exist in any mass ratio.
    • Homogeneous Mixtures: Uniform composition throughout (e.g., saltwater, brass).
    • Heterogeneous Mixtures: Composition varies and does not blend smoothly (e.g., salad, sand and salt mixture).

    Chemical Changes

    • Involve the conversion of substances into different chemical compositions (e.g., rusting of iron).
    • Characterized by the ability to undergo chemical changes, including flammability and acidity.

    Physical Changes

    • Changes that do not alter the substance's chemical identity (e.g., crushing a can, melting ice).
    • Observable properties that do not involve chemical reactions (e.g., state of matter, boiling/melting points).

    Crystallization

    • The process of forming pure solid particles from an impure mixture, often reached at the saturation point where no more solid dissolves.

    Chemical Properties

    • Ability of a substance to combine or change into other substances.
    • Determined by its chemical composition and ability to undergo reactions.

    Ions and Compounds

    • Compounds consist of ions with specific chemical formulas indicating the ratios of each element.
    • Examples of ions with their chemical names:
      • Ag+ and Br- form Silver Bromide (AgBr).
      • Fe3+ and O2- form Iron (III) Oxide (Fe2O3).

    Balanced Chemical Equations

    • Necessary for correctly representing the stoichiometry of reactions.
    • Examples of balanced equations:
      • Hydrochloric Acid and Barium Hydroxide: 2HCl + Ba(OH)2 → 2H2O + BaCl2.
      • Sodium Iodide and Bromine: 2NaI + Br2 → 2NaBr + I2.

    Atomic Structure

    • Defined by atomic number (number of protons) and atomic mass.
    • Example for isotopes: Thallium-204 has atomic number 123, atomic mass 204, with 81 neutrons.

    Reaction Types

    • Identifying the type of chemical reaction is essential for understanding the underlying principles and predicting products of reactions.
    • Diverse reactions include combustion, synthesis, and decomposition.

    Summary of Key Forms and Reactions

    • Chemical equations illustrate the reactants and products, showcasing conservation of mass.
    • Recognizing element and compound behavior aids in further exploration of chemical properties and reactions.
