Chemical Reactions
Process by which the atoms of one or more substances are rearranged to form different substance.
Chemical Reaction
Avagadro’s Number
6.02 x 10^23
Mathematical relationships between substances in a balanced chemical equation
Stoichiometry
attempts to explain the properties of gases
Kinetic Molecular Theory
P1 x V1 = P2 x V2
Boyle’s Law
Starting substances
Reactants
Used for individual elements
Atom
Compares any 2 substances in a balanced equation
Mole Ratio
Imaginary gas that follows 5 assumptions
Ideal Gas
V1/T1=V2/T2
Charles’s Law
Substances formed in the reaction
Products
Atoms with a charge
Ion
First step of Stoichiometry
Balance the equation
Occurs due to the collision of gas particles with the walls of their container
Gas Pressure
P1/T1=P2/T2
Gay-Lussac’s Law
Separates the two to show the direction of the reaction
Arrow
Covalently bonded compounds (nonmetal+nonmetal)
Molecules
Substance that runs out and stops the reaction
Limiting Reactant
Measured using a barometer or a manometer
Pressure
P1xV1/T1=P2xV2/T2
Combined Gas Law
Chemical reaction where oxygen combines and releases energy in the form of heat and light
Combustion
Formula Unit
Extra substance after reaction
Excess Reactant
Average kinetic energy of particles
Temperature
PV=nRT
Ideal Gas Law
