Wednesday Microsoft Word Formatting CREATING A TABLE #1 (2 points) From the description below, you are to insert a table containing all the information that is provided. An experiment took place that used three compounds: KH 2 PO 4 (aq), K 2 SO 4 (aq), KIO 3 (aq). In the experiment the students recorded various mass in grams of these compounds. In order the weights were 30, 35.4, and 397.3. Afterwards two separate trials were performed. The first trial was in milliliters; the recorded amounts were 18.5, 28.7, and 353.6. The second trial was recorded in kilograms; the recorded amounts were 0.030, 0.0354, 0.3973. Provide a title for the table.

Wednesday CREATING A TABLE #3 (2 points) Following the format from the online prelab to create a Chemical Table of Reagents with the following chemicals. Be sure to include all the appropriate information for each chemical. This will require some research. 1. 1M potassium nitrate 2. 0.2 M hydrochloric acid 3. Potassium permanganate 4. Ammonium carbonate Chemical name Chemical formula Molecular weight (g/mol) Concentration (M or mol/L) State (aq, l, s, g) NFPA Hazard diamond safety rating Ex) Hydrofluoric acid HF 20.0063 g/mol 1M Aqueous Health – 4 Fire – 0 Reactivity – 1 1M potassium nitrate KNO 3 101.1 g/mol 1M Liquid Health – 1 Fire – 0 Reactivity - 0 0.2M hydrochloric acid HCl 36.46 g/mol 0.2M Liquid Health – 3 Fire – 0 Reactivity - 1 Potassium permanganate KMnO 4 158.034 g/mol 0.05M Liquid Health – 1 Fire – 0 Reactivity - 0 Ammonium carbonate (NH 4 ) 2 CO 3 96.09 g/mol 1M Solid Health – 2 Fire – 0 Reactivity - 1
