This assignment was a quiz on Percent composition, Empirical, Molecular Formula, and Hydrates. This quiz consisted of 5 questions where each question had its own subject. I have chosen this assignment as I can look back and use it to grow. I did not study for this quiz and it reflected with my grade being a 20 out of 100. During the quiz, I was unable to understand what the question was asking me for. I also struggled because I did not know the correct equations to use for specific problems. I can use this to learn to actually study the correct equations and understand why we use certain equations for certain problems. 

This assignment was a packet we were given about water and PFAS. We had to watch a couple videos on what PFAS and water are and their purpose. We were then tasked to do our own research on these two substances and create a CER. In this CER we are gonna argue if the water at STEM is safe for us to drink. We found that STEM/ South Orange's water is safe to drink however does contain high amounts of inorganics and other chemicals that are harmful. In the end, we created a poster to discuss our findings on PFAS and explain why they are bad for us. I have chosen this assignment because I am proud of the work I put into this assignment. My group and I were successful in completing this packet and creating this poster. We created a detailed and informative poster which explained all of our findings.
