Document Summary
N2 as a diatomic (two non-metals) molecule - present only in the atmosphere. Unable to be broken down into n by the body; only by plants. N used to bond to other molecules in the body. Chemistry as the scientific study of matter; its properties, its transformations, and the qualitative, quantitative, and energetic changes associated with these transformations. Experimental science by nature of scientific method (ie. astronomy vs. astrology - experimental vs. faith) Scientific method breakdown: observations, hypothesis - revise if not supported, experiment - test hypothesis using control (null/no change) group and experimental group, model/theory - revise if not supported, further experimentation - tests based on your model. The hypothesis as an indefinite answer of sorts; more of an i think than an if-then . Matter as the stuff of the universe; anything that has mass and occupies space (ie. stars, planets, elements) Can be classified as pure substances or mixtures.
