Mixtures - Variable Composition Pure Substances - Constant Composition Homogenous Mixture - A mixture in which the composition is uniform throughout Heterogenous Mixture - A mixture with uneven distribution of different substances, solids, liquids, gases. Elements - A molecule composed of one kind of atom; cannot be broken into simpler units by chemical reactions. Compunds - A pure substance that contains two or more different elements in a fix porportion

us knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning Experiments - answera procedure carried out to refute or validate a hypothesis. They help students understand the cause- and - effect relationship by demonstrating what outcomes occur when a particular factor is manipulated independent variable - answerelement manipulated in the experiment dependent variable - answerwhat the scientist...

Experiment # 5 Bonding Type by Solubility, Distillation, and IR Spectroscopy Purpose: Different methods to identify inter and intramolecular bonding types. Procedure: A. Solubility 1) Place sample of KCl into a test tube filled with water. Take note of any layers separating the water with the added material. Mix the materials together in the test tube. Note if the mixture is homogenous or remains separated. 2) Repeat the process each for pentane, n-propyl chloride, ethyl alcohol, n-butyl...
