Document Summary
Balance the elements one at a time by using coefficients balance elements that occur more than twice in an equation last check each atom or ion to make sure that its balanced reduce all coefficients to the simplest ratio. Halogens: group 17 elements occur naturally in compounds because of high reactivity form diatomic molecules. Gilbert lewis basic bonding theories electron dot / lewis. Change of state - change of temperature temperature. Scientific law: describes the ratio between observed facts; it can be a qualitative statement or mathematical formula scientific theory or. Diffusion: the mixing of gases by dispersion from a region of higher concentration to one of lower concentration: as particles diffuse, they collide with particles in the air mean free. Path: the average distance a particle travels between collisions in a given gas sample; normally a very small distance.
