This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

Physical and chemical ProPerties
Did you observer any chemical changes in this experiment?
Yes
What evidence did you use to decide that something was a chemical change?
I observed during the application of the hydrochloric acid to some of the substances bubbling, and smoking
Give at least two examples of chemical changes you observed. green changed form blue to application of HCL to Mg smoking and bubbling and CuCO3
