Pre Lab Chemistry of Oxygen

The Chemistry of Oxygen: Basic and Acidic Oxides and the Periodic Table Pre Lab Report The objective of the experiment will be to perform and to observe the reactions of oxygen with several metallic and nonmetallic elements. We will determine whether these oxides behave as an acid or a base in aqueous solutions. We will perform this experiment by decomposing hydrogen peroxide by using a catalyst. We will burn certain elements inside a vessel that will be used to capture the oxygen decomposed by the H2O2 and then capture the contents. Once we captured the oxides, a small amount of water will be added so that a universal indicator will be used to determine their acidity.

Campbell's Biology, 9e (Reece et al.) Chapter 3 Water and Life Life evolved in the ocean, and the chemistry of life occurs in an aqueous environment. These questions explore the properties of water that are important to sustain life?s chemical processes, organismal physiology, and interactions of organisms with their environment. Quantitative properties such as heat content, molarity, and pH are also addressed. A few questions address how human activities affect the global environment through acid rain and acidification of the ocean. Multiple-Choice Questions 1) In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by A) hydrogen bonds. B) nonpolar covalent bonds. C) polar covalent bonds. D) ionic bonds. E) van der Waals interactions.

Conversions Regarding the Metric System and some Associated Formulas By Toomuchswag Sources: My Chemistry Notes and http://www.simetric.co.uk/siprefix.htm for some verification Most of the world besides the United States uses the metric system, a much simpler measuring tool according to many. The Metric system works in powers of ten: The prefixes work like this: Kilo Hecto Deca R (this is the regular unit, be it meters, grams, etc. we have given it the letter R) Deci Centi Milli Some important formulas: Density: Mass/Volume 1calorie or cal is the amount of energy required to raise the temperature of water by 1 degree Celsius

Chapter 7 Vitamins The Nature of Vitamins A. Definition - Vitamins are organic substances needed by the body in small amounts for normal metabolism, growth and maintenance - Coenzymes are substances that activate enzymes - do not provide energy B. Classification - major distinguishing characteristic of vitamins are their solubility in either fat or water - measured in micrograms C. Fat Soluble Vitamins - are absorbed from the intestine in the same way as fats, and like fats they can be stored in the same way - A, D, E, K - toxicity from vitamin A and D can be fatal D. Water Soluble Vitamins - B vitamins and C ? less stable to environmental influences; only B12 stored for any length of time Vitamin A A. Forms - necessary for vision

Essential Chemistry for Biology Chapter 2 1. There are 92 naturally occurring elements on Earth. What is an element? substances that cannot be broken down 2. Four of the elements oxygen, carbon, hydrogen and nitrogen make up about 96% of the weight of the human body. Oxygen is the most abundant element in the body. 3. Trace elements are required in very small amounts, but we cannot live without them. 4. Why is the trace element iodine important in the body? essential for hormone produced by thyroid gland 5. Why is the trace element fluoride important in the body? needed component of healthy bones and teeth 6. Know the chemical element for each of the following symbols: C; carbon H; hydrogen O; oxygen
