Mixture: a combination of two or more substances in which the substances retain their distinct identities. Homogenous mixture/ solution: the composition of the mixture is the same throughout. Heterogenous mixture: The composition is not uniform Chemistry: The study of matter and the changes it undergoes Elemtn: a substance that cannot be separated into simpler substances by chemical means Compound: a substance composed of atoms of two mor more elements chemically united in fixed proportions Extensive property depends on how much matter is being considered: mass, volumeetc Intensive property does not depend on how much matter is being considered: Density F=MA Forces Electromagnetic Force: Force between electrically charged objects or magnetic materials Gravitational force: The attractive force between objects due to their masses Weak Force: Force responsible for some forms of radioactive decay

Unformatted text preview: Strong Force: Force binding the protons and neutrons in nucleus together, overcoming the electromagnetic repulsion between the positively charged protons Energy Work = F X D S.I. unit of energy: joule (j) 1 J = 1 Nm = 1 kg m2/s2 Kinetic Energy = 1/2 mv^2 Potential Energy ( V )= mgh Coulombs law: V = (q1q2)/(4 pi Gr) G = 8.8541878 X 10^-12 C^2/(Jm) Hooks Law: 1/2k(x-x0)^2 Radiant Energy: energy contained in electromagnetic radiation, such as X-rays, radio waves, and visible lightr. Thermal energy: energy associated with the random motion of atoms and molecules. Thermal energy is extensive while temperature is intensive Ion: has a charge positive or negative Cation: positive Anion: negative0 Allotrope: O2 or O3 (ozone) Ternary Compounds: 3 elements Avagadros number: 6.022 X 10^23...
