“Classifying Chemical Reactions - Lab Report”
I - Introduction -
Chemistry is the study of the composition, structure, properties and change of matter. In chemistry, chemical and physical changes are used to help scientists understand how different substances react given various circumstances. A chemical change is any change resulting in the formation of a new chemical substance(s). A physical property is any change that does not involve the chemical makeup of a substance at all. In total there are five (5) chemical reactions. The reactions are: Single-Displacement, a single element replaces another element in a compound; Double-Displacement, an element from both compounds switch places; Synthesis, elements join together into a compound; …show more content…
Approximately ¾ inch of the Copper(II)Carbonate was placed into a test tube. The test tube, by means of a clamp, was fastened to a ring standard to be heated by the Bunsen Burner. A one hole rubber stopper fitted with a glass tube was fitted into the top of the test tube. A measurement of 5 ml of the Limewater was placed into a graduated cylinder. With test tube holders, a separate test tube was held over the end of the glass tubing to collect the gas produced. The Copper(II)Carbonate was heated until it completely changed its color. The Bunsen Burner was turned off and the Limewater was immediately poured into the test tube used to collect the gas. Observations were …show more content…
The ability to predict products helps scientists hypothesize an outcome that can be proven or disproven. With the ability to predict precisely, scientists can get very close to the outcome just from the given information, if not perfectly predict it. This speeds up the experiment and allows scientists to continue with their work in an efficient manner. By classifying chemical reactions, scientists are able to understand the similarities between various reactions and further the understanding of the behaviour of varying reactants under given circumstances. These abilities, once perfected, provide the science field with an efficiency and knowledge that can be applied to greater concepts of higher
