CLINICAL CHEMISTRY – defined as the study of biochemical processes associated with health & dse & the measurement of constituents in body fluids or tissues to facilitate dx of dse - dual nature since it’s both a basic and applied science thus clin chem. technologists & technicians should have an understanding of the physiologic & biochemical processes occurring in the body‚ as well as technical skills to perform the various tests - chemistry in connection with the management

Testing the pH of Common Household Substances Lab Background Information: The pH scale is used to determine the acidity or basicity level of liquid solutions. If a solution scores a pH level of 1-6 it is an acidic solution‚ 1 being the most acidic and 6 being the least acidic. If a solution rates a pH level of 7 it is a neutral solution‚ meaning it is neither an acidic nor a basic solution. Lastly‚ if a solution is 8-14 on the pH scale it is a basic solution‚ 8 being the least basic and 14 being

Assessment 1) Describe the difference between ionic and covalent bond. Ionic bonds have electrostatic forces that hold cations and anions together‚ and are electronic neutral. Covalent bonds are bonds that don’t give or take any electrons. In stead they share the elctrons 50) Which of these compounds contain elements that do not follow the octet rule? Explain. a) NF3: 5 + (7*3) = 26 b) PCl2F3: 5 + (7*2) + (7*3) = 40 c) SF4: 6 + (7 *4) = 24 d) SCl2: 6 + (7*2) = 20 The answer is “d”

Combustion of Acetylene (ethyne) Rx: Back Why I don’t do acetlyene explosions in our lab.... Combustion of alkanes A quick review.... • Combustion reactions of alkanes consist only of C and H (hydrocarbon) • require O2(g) as a reactant • produce CO2(g) and H2O(g) and a large amount of energy!! Oxygen can be the limiting reagent which can lead to Incomplete combustion. For complete combustion of a hydrocarbon‚ oxygen must be in excess. If there isn’t sufficient oxygen‚ incomplete combustion occurs

In the 18th and 19th centuries scientists wrestled with identifying and describing the nature of the “stuff” that produced change. One concept that became popular for a while was that of “caloric” (what we now call heat). “Caloric was originally conceived of as a quantity that would flow from a hotter object to a cooler one that would warm up as a result. It answered the need for a way for the cause of warming to get from here to there. Not only did caloric serve as a cause for warming‚ it
