Subtances entering a reaction

Subtance formed from reactants

Is a shorthand expresion for a chemical change

Contains the same number of each kind of atom on each side of the equation

two reactants combine to give one product

one element reacts with a compound to replace one of the elements of that compound, yielding a different element and a diffrent compound

two compounds exchange partners with each other to produce tow diffrent compounds

Reations that liberate (release) heat

Reactions that absorb heat

The quantity of heat produced by a reation

Mixtures that contain only hydorgen and carbon

The amount of energy to start a chemical reation

The Sum of the atomic masses of all the atoms in an element or compound

the area of chemistry that deals with quantitative relationships among reatants and products is knows as Stoichimetry.

The reaction is the calculated amount of product that can be botained from a given amount of reactant, according to the chemical equation.

is the amount of product that we finally obtain

is the ration of the actual yield to the theoretical yield multiplied by 100

• A theory based how gases behave.
• States that

• 1. Gases consist of tiniy particles
• 2. The sistance between particles is large compared with the size of the particles themselves
• 3. Gas particles have no attraction for one another
• 4. Gas particles mone in straight linesin all direction, colliding freqently with one another and with the wall of the container
• 5. no energy is lost by the collision of a gas particle with another gas particle or the walls of the container. All colitions are elastic
• 6. the average conetic energy (KE) of a particle is expressed by the equation

A gass that behaves exactly as outlined by the theory (KMT).

The ability of two or more gasses to mix spontaneoulsly until they form one the form a uniform mixture.

is the process by which a gas molecules pass thorugh a very small hole

the rate of effusion was dependent on the density of a gas.

is defined as force per unit area.

the gases in the atmosphere exert a pressure known as

A device that measures atmosphere pressure

is the pressure exerted by a column of mercury 760 mm high at a temperature 0 degree celcius

The relationship of a P and V is known as Boyle's Law. V 1/p or P₁V₁ = P₂V₂
