Definition of Matter
Matter is anything that has mass and occupies space.
Classification of Matter based on Physical State
Matter can be classified into solid, liquid, and gas.
Intermolecular Forces in Solids, Liquids, and Gases
Solids have very strong intermolecular forces, liquids have stronger IMF than gases, and gases have very weak IMF.
Dalton's Atomic Theory Principle 1
Matter is made up of very small indivisible particles called atoms.
Limitation of Dalton's Atomic Theory
Dalton's theory does not account for subatomic particles such as electrons, protons, and neutrons.
Mole Concept
A mole is the amount of substance that contains as many entities as there are in 12 grams of Carbon-12.
Molecular Mass Calculation
Molecular mass is the sum of the atomic masses in a molecule.
Empirical Formula vs Molecular Formula
Empirical formula represents the simplest ratio of atoms, while molecular formula shows the actual number of atoms in a molecule.
Stoichiometric Coefficients in Reactions
Stoichiometric coefficients in a balanced equation represent the molar ratios of reactants and products.
Limiting Reagent
The limiting reagent is the substance that is completely consumed in a chemical reaction, limiting the amount of product formed.
Key Points about Matter
- Matter has mass and occupies space. - Classified into solid, liquid, and gas. - Intermolecular forces vary: strong in solids, moderate in liquids, weak in gases.
