an !OH (hydroxyl group, Section 1.3A). Which structural formulas represent the samecompound? Which represent constitutional isomers?
Student: Sarita Peterson October 13, 2015 Lab Partner: Domonique McPhall Chemical Reactions of Copper Objective: The objective of this lab was to understand the law of conservation of mass more in-depth and to become more familiar with the other lab techniques and types of experiments. Introduction: In this experiment copper ribbons will be converted into different stages through the process of many different chemical reactions. These chemical reactions include the disappearance of a solid, the formation of a gas and precipitate, color changes, and temperature changes. At the end of the experiment the copper that is converted back into a solid will be weighed in an attempt to verify the law of conservation of mass. Procedure: We followed the procedures outlined in the course lab manual, CHM 111 General Chemistry Laboratory Manual, LaSalle University, Fall 2015 Experimental Results: Cu = 1.07 g Copper #1- Copper #2- 1.55 g 0.95 g Cu Start = Cu End = 1.00 g 0.95 g Questions: In-Lab Questions: 1.
