Homogenous mixture - Study guides, Class notes & Summaries

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

Solution - homogenous mixture of 2 or more substances Solute - What is being dissolved Solvent - What is doing the dissolving Saturated - The solution is at the maximum amount of solute Supersaturated - There is more solute dissolved than usually allowed because of a change in the pressure or temperature during dissolution Unsaturated - The solution does not have the maximum amount of solute for its volume of solvent ppm (parts per million) - grams of solute/ grams of solution ...

scientific notation correct answer: 3.94 x 10⁷= 0. = 8.0 x 10⁻⁶ measured v. exact numbers correct answer: measured = obtained through measurement and are uncertain exact = obtained through counting and are certain precision v. accuracy correct answer: precision = close to each other accuracy = close to the actual number conversion factor correct answer: a ratio of equivalent measurements used to convert a quantity from one unit to another density correct answer: d = m/...

Characteristics of Quantitative Research numerical data (quantity); hypothesis & research procedure are stated BEFORE data collection; large sample size; rely on statistical procedure; low interaction with subjects; rely on controlling, measuring, and generalizing; objective by nature Quantitative Methods/Designs survey research; correlational research; causal comparative; experimental; single subject experimental Sampling techniques for quantitative research simple random; stra...

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...
