BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

Total continuity equation is the principle of the conservation of mass when applied to a dynamic system. The unit of this equation is mass per time. In overall balance‚ only one TCE can be written. CCE is based on component balance. Unlike mass‚ chemical components are not conserved. If reactions occur on a system‚ the number of moles of an individual component will increase if it is a product and will decrease if it is a reactant. The unit of CCE is moles of component per unit time. While EE‚ the
