ABSTRACT: The lab of “observations of chemical changes” was to observe the changes that occur in chemical reactions and attempt to interpret these changes. In these experiments it taught me how to interpret chemical reactions with acids and bases. Also, how one chemical can have many different reactions when combined with other chemicals and how to interpret each reaction as what it could mean. I discovered not only how to measure out a well-balanced chemical combination to receive a reaction but to know how to test for acids and bases using a few different methods. Other tests also included in this experiment were testing for Sodium Bicarbonate, and Starch.
Trends of the Periodic Table of Elements Introduction The objective of this experiment was to establish trends in the Periodic Table of Elements, involving the characteristics of elements in the same group and/or period. In Part 1, the melting point trends of metals in Group 1, Period 3, Period 4, Period 5, and Period 6 were observed, using the Web Elements website (http://www.webelements.com/), and then were graphed (by each Group or Period individually) to display the trends. Trends were observed in all graphs, and the melting points were related to multiple variables, such as electron configurations, nuclear charge, shielding, atomic radii, and cohesion energies. In Part 2, Group two nitrates were mixed with different solutions, and were observed for indications of chemical reactions (precipitate formation and solubility) that formed periodic trends. In Part 3, six specific metals were reacted, in individual test tubes, with hydrochloric acid and a variety of different metal ion solutions, in order to find if a reaction of metal displacement happened.

• #1 Observation of Chemical Changes • Maurice Smith • September 5, 2012 2:33pm • Location • CHEM 1211-06 • In this lab project we are expected to examine the chemical changes of some of the most basic chemicals. We are expected to take the different chemicals and match them together against two paper backgrounds (white, black) to observe the chemical changes. We will also test starch amounts with household foods and observe the chemical changes. In addition to the foods, we are to take some household chemicals (which will be listed) and test them with some of the samples that we have in the Observation of Chemical Changes lab kit.
