A description of some successful labs we did in the class.
Flame Test Mini-Lab
In the flame test lab we put wooded splints soaked in an assortment of chemicals into a flame and watched to see what color the flame was. In this lab I learned what metals in chemicals create different flame colors, such as Na produces a dark orange flame, Li produces a hot pink flame, and Cu produces a bluish green flame. The topic being covered in class during this lab was electron configuration, ground state, and excited state. In this lab my results were generals consistent to what my results should've been, with the exception of the mixtures.
The Iron-Copper Molar Tango: A single Replacement Reaction
In this lab we calculated the mass and number of moles f copper produced and the number of moles of iron that reacted and also determined the molar relationship between iron and copper. We did this by mixing steel wool with copper(II)sulfate until it was a eraser shaving like mixture and poured it into a funnel and left it over night until it created a solid. I learned in this lab that in steel wool there is more Cu than Fe. During this lab we were learning reaction types and balancing equations. My results were very good in this lab.
