Matter
Anything that has mass and volume.
Mass
The amount of matter in an object.
Volume
The amount of space an object occupies.
Elements
One type of atom that can exist as atoms or molecules.
Molecules
Two or more atoms chemically bound together, which can be the same or different types of atoms.
Compounds
Two or more different elements with a set ratio.
Isotopes
Atoms of the same element with a different number of neutrons.
Mixture
Contains two or more substances.
Homogeneous Mixture
One or more substances dissolved in another substance, resulting in a uniform composition.
Heterogeneous Mixture
A mixture of substances that remain physically separate.
Filtration
A technique to separate solids from liquids and gases, where a filter allows only the fluid to pass.
Distillation
A method to separate liquids based on their different boiling points.
Chromatography
A technique that separates liquids based on their solubilities.
Solid
Has a definite shape and volume with low energy, having a regular particle pattern.
Liquid
Has a definite volume and takes the shape of its container, with some energy allowing particles to slide past each other.
Gas
Takes the shape and volume of its container, having high energy with particles moving quickly and spreading out.
Endothermic
A process in which the system absorbs heat from its surroundings.
Exothermic
A process in which the system releases heat to its surroundings.
Convection
Energy transfer due to the bulk motion of fluids at different temperatures.
Conduction
Energy transfer due to temperature differences through particle collisions.
Radiation
Transfer of energy through electromagnetic waves.
Acid-Base Reaction
A reaction between an acid and a base that produces a salt and water.
Precipitate
An insoluble solid that forms when two aqueous solutions mix.
Solubility Rules
Guidelines to determine if a substance will dissolve in water.
Oxidation
The loss of electrons during a reaction.
Reduction
The gain of electrons during a reaction.
Combustion Reaction
A reaction where a substance reacts with oxygen to produce carbon dioxide and water, releasing heat and light.
Limiting Reactant
The reactant that is completely used up in a chemical reaction and limits the amount of product formed.
Boyle's Law
The relationship between pressure and volume of a gas, stating that pressure increases as volume decreases.
Charles's Law
The relationship between volume and temperature of a gas, stating that volume increases as temperature increases.
Ideal Gas Law
A relation between pressure, volume, number of moles, and temperature of an ideal gas, expressed as PV=nRT.
Molar Mass
The mass of one mole of a substance, expressed in grams per mole (g/mol).
Percent Composition
The mass percent of each element in a compound.
Empirical Formula
Represents the simplest whole-number ratio of elements in a compound.
Molecular Formula
The actual number of atoms of each element in a compound.
