Ch 6 Inventory List

Vocabulary flashcards covering types of chemical reactions, components of chemical equations, stoichiometry, and fundamental chemical concepts from the lecture notes.

Single Replacement Reaction

One element replaces another in a compound.

Double Replacement Reaction

Exchange of ions between two compounds.

Oxidation-Reduction (Redox) Reaction

Reactions involving electron transfer.

Oxidation

Loss of electrons (often gain of O or loss of H).

Reduction

Gain of electrons (often loss of O or gain of H).

Combustion Reaction

A substance reacts with oxygen, producing energy (heat/light) often with CO2 and H2O.

Products

The substances formed in a chemical reaction.

Chemical Equation

A symbolic representation of a chemical reaction using formulas.

Coefficient

The number in front of a formula in an equation, showing how many units participate.

Balanced Chemical Equation

An equation with equal numbers of each atom type on both sides.

Stoichiometry Calculations

Quantitative calculations involving reactants and products using mole ratios.

Mole-to-Mole Ratio

The ratio of moles of one substance to another from a balanced equation.

Combination Reaction (Synthesis)

Two or more substances combine to form one product.

Decomposition Reaction

One substance breaks down into two or more products.

Chemical Reactions

Processes where substances (reactants) change into new substances (products).

Molecular Mass

The sum of the atomic masses of all atoms in a molecule.

Formula Mass

The sum of atomic masses in a formula unit (used for ionic compounds).

Mole (mol)

A counting unit: 1 mole = 6.022 × 10^23 particles (atoms, molecules, or ions).

Avogadro's Number

6.022 × 10^23, the number of particles in one mole.

Millimole (mmol)

One-thousandth of a mole (0.001 mol).

Molar Mass

Mass of 1 mole of a substance (g/mol), equal to its molecular or formula mass in grams.

Precipitate

A solid that forms when two solutions react and an insoluble product appears.

Aqueous Solution (aq)

A solution where water is the solvent.

Metabolism

The sum of all chemical reactions in living organisms.

Law of Conservation of Mass

Matter is not created or destroyed in a chemical reaction.

Reactants

The starting substances in a chemical reaction.
