SG Chem2 week 6

The week started off with a lab labeled Sticky Tape Activity. We were instructed to place 2 pieces of tape on top of each other which would cause them to have a charge.  Then we placed them next to pieces of tape hanging from a beam.  There is a bottom and a top tape that are changed and that have been hanging. We noticed that the bottom tape was attracted to the top tape and the top tape was attracted to the bottom tape.  Therefore, we can make the simple conclusion that opposites attract.  Here are a few tables that allowed us to comprehend the lab very easily.

Another worksheet we did which was based on the Sticky Tape Activity, was the Post-Lab worksheet. This worksheet was based on the topic of atoms and their physical appearances throughout the lab. It is also another way of showing how the atoms inside the tape change and move around as the lab goes on.  Even though I am still slightly confused on this topic, it was easier to comprehend the idea after we could see the physical change in atoms.  Here are examples of the atoms we drew in class. Theses photos show how the atoms in in tapes change as they get closer to one another.  

As we continued our studies throughout the week, we accomplished the learnings from the Electrolysis of CuCl2 Lab. We worked the positive and negative side of our experiment.  The clarify the understanding from this experiment, we are going to learn what happened when chlorine and copper is combined.  In the experiment, the chlorine went to the positive side and the copper went to the negative side of the electors.  Therefore, we can come to the conclusion that copper is positively charged because it was attracted to the negative side.  In the previous experiment, opposites attract.  In addition, chlorine is negatively charged because it was attracted to the positive side.   After we let the experiment sit over night then start running again a few hours before class, we noticed some amazing changes in the experiment from the pervious day.  The first day we started the experiment, we only noticed the smell of chlorine and the bubbles it was forming.  On the next day, we noticed the red copper physically forming on the negative side of the experiment.  In addition, the color change from the chlorine.  The experiment went from blue to a yellowish/greenish.  To have a visual representation of the second day of the experiment, here is a photo of the experiment.  

 The last worksheet we were assigned this week was titled Chemistry-Unit 6 Worksheet 1.  We are working with the specific formulas of different molecules together.  Once we found the formulas and particle diagrams and found different patterns betters the numbers and formulas.  We can conclude that there are hidden numbers at the top of the periodic table that can be helpful to us.  Here is how we filled out the periodic table after finding theses numbers from the patterns in the formals.

Using the numbers on top of the element columns, we can find the formula for any given element compound.
