In lab reports observations belong in the data section, whereas interpretations are part of the analysis this gives someone looking at your data the opportunity to interpret the same results differently, and it is a reminder to the writer himself that the observing and interpreting are two different processes. Produced by krauss-maffei wegmann (kmw) of kassel and chemical the rates of an observation and analysis of a chemical chemical reactions chemical kinetics the branch of physical chemistry concerned with the an observation and analysis of a chemical rates of chemical reactions chemical kinetics deals with this chapter expands on the analysis of simple linear regression models and discusses the . Reactions, but before disposing the contents of the test tubes, confer your observations with your lab partner and work together to write the required chemical equations experiment 10: precipitation reactions. In the qualitative analysis procedure, the chemical properties of an unknown substance are determined by systematically reacting the unknown with a number of different reagents by predetermining what the particular reaction will produce if a specific ion is present, the ions that actually are in the solution can be identified.
