CHM 151 Exp #8 Copper Cycle General Observations: Your instructor has provided pictures and video taken during each of the five different steps (reactions) during this experiment. Please refer to them as you write out your general observations for the experiment. For example: Table 1- General Observations of the Copper Reactions in this experiment Step 1: Cu(s) + 4HNO3(aq) → Cu(NO3);(aq) + 2NO:(g) + 2H;O(I) Reddish brown gas is produced and the copper dissolves to form a blue solution. The reaction is producing heat (beaker is getting hotter). Since there are five steps in this series there should be general observations written down for each reaction (step) in the series (5). It is important to record observations of color, gas production, precipitate production, dissolving of solids and changes of temperature since these types of general observations are all indicators of a chemical reaction taking place. You will find numbers written in parentheses for the questions placed in the procedure corresponding to the questions in the question section. You may find it more convenient to answer these questions as you are working through the different reactions in the lab, rather than trying to go back and remember what was happening later. Data Section: The following items should be included in the data section in your lab notebook and any lab report. (1) General Observations should be recorded – what did you observe during the experiment? (2) Write the balanced chemical equation for this reaction. (3) Data Table - The masses are from an actual experiment completed on Friday, March 20, 2020. 1. Initial mass of copper 0.4944 g 2. Mass of copper and evaporating dish 48.0337 g 3. Mass of evaporating dish 47.5789 g 4. Mass of recovered copper 0.4548 g

Please refer to them as you write out your general observations for the experiment. For example: Table 1- General Observations of the Copper Reactions in this experiment Step 1: Cu(s) + 4HNO;(aq) → Cu(NO3);(aq) + 2NO:(g) + 2H;O() Reddish brown gas is produced and the copper dissolves to form a blue solution.
