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.

C) Each organic molecule is modular and the smaller molecules or monomers can be constructed into larger molecules or polymers (Open Learning Initiative, 2015, pg.63).

There are many types of chemical bonds and forces that bind molecules together. The two most basic types of bonds are characterized as either ionic or covalent. In the lab we separated Citric Acid, Calcium Chloride, Sucrose, Potassium Iodine, Phenyl Salicylate ,and Sodium Chloride into two groups ionic and Covalent bonds .The Chemical Difference between ionic bonding and covalent bonding is, a covalent bond is formed between two nonmetals that have similar electronegativities. Metals are left half and center of the Periodic Table and Nonmetals are upper right of the Periodic Table. The electrical attraction between large numbers of cations and anions which is the transfer of the

In this lab we are going to be working on chemistry and a chemical reaction. A chemical reaction is when two or more chemical meet each other causing a change or reaction to the chemicals being mixed. We are going to do a chemical reaction ourselves, we are going to Represent this chemical reaction with milk, food coloring and dish soap. When you see this chemical reaction known as a non-polar molecule, although this is not an explosion or an over flow due to gas and pressure causing a mess, it is still really interesting to see and it is simple. Well going through this experiment, I want you to ask and answer why the food coloring travels away from the dish soap and what role

In this lab, we tested how chemical reactions happen when enzymes and reaction rates are effected. For the chemical reaction, we broke down the substrate ONPG into galactose and o-nitrophenol. Using ONPG as the substrate allowed us to see what was actually going on. When breaking down ONPG, the o-nitrophenol turns yellow, unlike lactose which is colorless. There are two ways in which we can manipulate the reaction rate and activation energy in this experiment. Increasing the heat by exposing enzymes to higher temperatures results in faster progression with the reaction. If the temperature were to drop, the reaction rate would slow down since molecules move faster at higher rates, proving this indeed has an effect on the rate. The other option

as the cytosine at position 34, cytosine at position 12, and tyrosine at position 29. In

In our everyday life, we witness many chemical reactions. Some fun reactions you may know about are mentos and pop or vinegar and baking soda. Those two reactions are visible to the naked eye. You aren't able to see photosynthesis completely but you know that it take place because a plant grows. Now what about the chemical reactions that you aren't able to see? How do you know when they are complete? Well let me explain this bright and interesting new discovery.

The students are introduced to the purpose and structure at the beginning of the course. The learners were introduced to the purpose and structure of the course in the course syllabus, in the orientation, and in the CHM 1025-Introductory Chemistry video. The course description in the syllabus clearly describes the purpose for this course.

Introduction: The goal of this experiment was to practice using the FirstGlance in Jmol molecular visualization to examine key structural features of proteins. This work is important because protein structure can be related to function, multiple-sequence alignments and evolutionary preservation, and designing drug. FirstGlance in Jmol makes it fairly easy to perceive structure-function relationships in the protein you chose. Using FirstGlance, it is easy to visualize and distinguish chains, and disulfide bonds are obvious. Alpha helices and beta strands are evident due to the "cartoon" secondary structural schematic.

a) The tertiary structure refers to the structural arrangement of amino acids that are found far away from one another along the polypeptide chain. The tertiary structure is overall a three dimensional shape of a protein molecule. It will bend and twist to achieve maximum stability. The shape of a tertiary structure is made when the secondary structure folds in on itself and is held in place by many bonds and interactions formed by the R groups in the amino acid chain. The bonds and interactions involved are hydrogen bonds, ionic bonds, hydrophobic interactions and disulphide bonds. These bonds and interactions are located in different areas of the tertiary structure, the hydrogen bonds are located inbetween polar R groups, ionic bonds are located between charged R groups, hydrophobic interactions are located between nonpolar R groups and disulphide bonds are formed generally in the endoplasmic reticulum by oxidation ."Hydrogen bonds may form between different side­chain groups." Hydrophobic interactions are brought about in an aqueous site. The tertiary structure is held together mainly by interactions that are located at the R groups.
