Experiment #17 Classification of Chemical Substances Prepared for: Dr. Robert O’Reilly By: Kudaibergenov Baizak 20.11.2013 Nazarbayev University Introduction While many thousands of substances are known‚ they can be classified into a few simple categories based on type of bonding that exists among the atoms in the substance. Bonds are chemical forces that hold atoms together to form molecules or compounds. These categories are ionic‚ molecular and metallic substances.

21st‚ 2013 MC 205 Week 4 Instructor Rein Chemical Stress Testing A chemical stress test is used when a traditional stress test (called a cardiac stress test) cannot be done. A cardiac stress test requires you to walk on a treadmill or ride a stationary bicycle until your heart rate reaches a level where your heart is “stressed”. You may not be able to participate in this kind of test if you have a condition such as a stroke. In this case‚ a chemical stress test is used. This test is used to help

Purpose The purpose of this lab was to observe chemical changes which result in different properties. Procedure First all materials needed for experiment were gathered. Using a sanitized scissor‚ all the pipets were cut open at the very top of the pipet. The 96 well plate was used for combining the chemicals to see what the reactions were and the 12 well plate was used for holding the pipets filled with chemicals that had been opened. In column 1 row A of the 96 well plate; two drops of NaHCO3 was

Lab 4: Physical & Chemical Properties Purpose: The purpose of this lab is to distinguish if different substances react to heat or cold and if a solution is added to it during the experiment will it change the substance or leave it the same. Throughout the different tests each substance is put through a series of tests to determine if it changes in any way in regards to color‚ odor‚ or consistency from the start of the experiment. The results will be documented in table 1. Data Table 1: Solubility

Naming Chemical Formulas Chemical Nomenclature There are over 19 million known chemical substances. Without some type of system‚ naming these substances would be hopelessly complicated. The system used in naming substances is called chemical nomenclature. There are two major divisions to the International Union of Pure and Applied Chemistry (IUPAC) system: inorganic nomenclature organic nomenclature Organic compounds contain carbon‚ usually in combination with hydrogen‚ oxygen‚ nitrogen
