HSC Chemistry Assignment

In experiment 3.11, we found out whether or not a larger amount of a liquid would get hotter when it boils. To answer this, we heated a specific amount of unknown liquid and recorded the temperature every fifteen seconds. In our scatter plot, we were able to find the boiling point of our liquid. We know that the slope of our graphs is when the liquid molecules were moving around and heating up. The plateau of our graph points is where the liquid started to evaporate and boil. This is were we found our boiling point at. Shantel and I decided that our boiling point was about 98º Celsius. If you had another slope in your graph, that was when you were simply heating the leftover gas. The histogram showed us that there were about equal amounts of data in the higher temperature (about 95º Celsius) bins for both 20mL of liquid and 10mL of liquid. Also, in the lower temperature bins (75º to 80º Celsius) there was about equal amount of data for 20mL of liquid and 10mL of liquid. There was 7 pieces of data for 10mL of liquid in the lower bins, and 6 pieces of data for 20mL of liquid. If a larger amount of liquid did have a higher boiling point, the clusters would be organized by volumes or amount. For example, all of the 20mL pieces of data would be in the higher temperature bins, and all of the 10mL pieces of data would be in the lower temperature bins or flipped. Rather, the bins were clustered by identity. The boiling point is a characteristic property.

* Copper, gold and aluminum are all alloyed with other metals to make them harder.

B. Claim: As we go from methanol  ethanol  1-propanol  1-butanol the dispersion forces increase.

A topic of great importance to all scientists is the identification of compounds, which is relevant in all aspects of their work in some way shape or form. Weather it may be determining what is causing sickness or what is polluting the air, it is very prevalent in the science world. In project 2, identification of cations and anions was preformed through a series of confirmation and elimination tests that ultimately led to identifying an unknown ionic compound made of cations and anions.

Day 1. Michael was coming home for vacation from college. When he got home he found out that

Thank you for your help in my application process for the National Honors Society. I really appreciate you taking the time out of your day to not only fill out the non-teacher evaluation, but to also come over and ensure that you would cover every important detail in the comment section. Your extra notes for my resumé have also been very helpful in giving it a better structure so that it is no longer a list, but a sort of story about my life’s accomplishments. Thank you again for all of your help and generosity, I am very

Responses and Answers Review Questions 1. Why is chemistry often called the central science? -Because it touches all other sciences. 2.

First off, I want to say thank you to my parents for supporting me. Mom, Dad, thank you for being there with me during difficult times. You support and understand me, this gives me the strength to continue fight through the challenges in life. Without you being here today and by my side, I would have given up. Next, I want to thank the administration. You have all contributed to making this school run smoothly but also have allowed us to have a good time. I, as many others, have enjoyed the monthly walks and fundraising activities, the cultural fashion show and the fun and exciting cultural festival with the live steel bad and African drummers. These are some experiences that some students have never been exposed to. Therefore, thank you for bringing new and exciting initiatives to PS/MS124. Mrs. Babb, you are a very loving and an easy person to talk to. You have made so many positive changes to PS124, one of which is allowing us middle schoolers to have student council. I would also like to thank my teachers, for sharing their knowledge. You have taken the time to explain assignments, make class interesting, challenge us beyond our knowledge, and inspire not just me, but all of us. I want to Mr. Heaton for granting me the position of secretary for National Junior Honor Society last year. This was a great opportunity and that allowed me to play a key role in the National Junior Honor

This is Samantha galindo from A&P 1, I feel as though ,earlier when we spoke, I was being rude about the way I was talking about my grades. I wanted to make sure I didn't make you upset or make you feel uncomfortable and think I was asking for a grade bump. It's just that I have been panicking lately since I do need to make a 70 In the class to pass my high school course. I am not asking for extra credit since I am aware that you have given the class many chances for extra credit and it is my fault for not keeping myself in check with the way I was studying and I also know that the grade I get is the grade I deserve. I would like to say sorry if I did perhaps do something that displeased you I some way.

I hope you had a wonderful break. Aayush could not hand in his lab on Friday because he had to get his tennis clothes for his first game. He told me that he went to your room and it was locked. He didn’t want to miss the game or be late to it so after that he went and exited the school to get the clothes from my car. Aayush told me that he was going to be late and could not hand it in to the mailboxes. Aayush was concerned that you were going to mark the lab late. Can you please excuse his late for this one time? Thank you.

I am writing this letter to express my sincere apology for what occurred in your class on Tuesday, April 4, 2017. My decisions were extremely poor and resulted in a unnecessary waste of time for you and I as well as the rest of the class. I may have not felt this way at first, but after having some time to think I now realize how disrespectful, rude, and pointless my actions were as well as how lucky I actually am to get off fairly easy.

On Monday, December 11th, I observed a General Chemistry class at Gustavus Adolphus College taught by Dr. Anna Volkert. This class was undergoing changes in order to best prepare the students identified as not having as many math skills (by a test) for organic chemistry or at least helping them pass chemistry if it was required for their major (like nursing). The class itself was a general stair step lay out facing a black board and screen, both were used by the professor during the lecture. There was little room for students to turn and talk to each other or form groups in the lecture portion. I know by talking with Dr. Volkert the students were also required to attend lab and a discussion section once a week, thus the lecture portion could focus on the content.
