Ion channel

lattice which then leads to having a high melting/boiling point. Graphite can conduct electricity due to having free electrons. Covalent substances do not conduct electricity unlike ionic substances this is because covalent substances do not have free ions or electrons therefore they cannot conduct…

For this experiment, a group was employed by the Environmental Protection Agency as analytical chemists. Their goal was to identify an unknown compound that has been discovered in a landfill in their hometown. Once they identified the compound, they would then have to determine both the chemical and physical properties of the compound in order to inform the townspeople of any potential dangers. During the first week of lab, the group was given a small bottle containing an unknown white…

Ionic and Covalent bonds are the two different types of bonds that hold atoms together, each having their own characteristics. The distance and charge determines the type of bond the molecules have. These bonds occur because atoms strive to obtain the ideal valence of 8. Some atoms need to gain or lose electrons in order to achieve the ideal valence. In a covalent bond, the electrons are being pulled by two atoms that are both nonmetals. In other words, the two atoms are sharing electrons, but…

Free radicals are molecules that have at least one unpaired electron. They are typically very reactive, due to their odd number of electrons. These molecules tend to try and gain or lose electrons so their highest energy levels can be filled. They will bond with other compounds in the body, sometimes combining with them, or even taking parts of intact molecules, resulting in even more free radicals (Walling). Free radicals can be formed by natural body processes, such as metabolism. They…

The stories Conducting Solutions, Energy Story, and the video Hands-On Science with Squishy Circuits have all helped me learn a lot more about electricity. The purpose of these sources were to help the reader to understand and inform the reader about how electricity is made. It also showed how easy it is to make electricity. These three sources have many differences and similarities but they all serve the same purpose. In the video Hands-On Science with Squishy Circuits it talks about how easy…

Covalent bonding occurs when atoms share pairs of electrons. Atoms will covalently bond with other atoms in order to gain more stability, which are gained by forming a full electron shell. By sharing their outer most valence electrons, atoms can fill up their outer electron shell and gain stability (Chem wiki) Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on…

Chemistry, oh chemistry! Chemistry is an interstmig subject. Withourt it we would not know many of the thigns we do today. However, with chemistry comes a lot of studying and hard work. There are three bonds in chemistry ionic, covalent, and hydrogen. Do not ask me why they named them this because I am unble to tell you this. However I can tell you that SCl2 is an ionic bond and NaCl is a covalent bond. Well, that is that the atoms in them form those types of bonds. Hard to belive I know, but…

completion of CEM 161 Section 009, under supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate. After comparing the results of these experiments we determined that our compound contained a halide. By using the flame test with a Bunsen Burner we also determined that our compound…

Afra Ankita Class 625 EV3 Test 3 The threshold for white was any intensity above 95%. The threshold for black was any intensity below 6%. This is because the first white surface that was tested for its reflected light intensity turned out to be 95%. The second test for white was 100%, the third was 97%. All these tests were made by using “Port View” on the robot.“Port View” can be found by going to “Utilities” on the robot’s screen. Then going over to the port that the color sensor is connected…

In this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…
