Data Analysis1.    Record the numbers of the days (e.g. 1 to 7) in the file name of your winter dataset. 2.    Include your formatted timeseries showing the concentrations of NO2, O3 and OX over seven days in the winter. Please upload either a PDF or a JPEG of your graph.  3.    What is the mean and standard deviation of O3, NO2 and OX in your win...

Problem 1 (15 marks)In the last decade, considerable attention has been paid to understand the properties of water solutions of the synthetic polyelectrolytes called x,y-ionenes (Figure 1). Ionene polymers can selectively bind to protoplasts that makes them potential cancer drugs. Besides this, the applicability of ionenes as non-vector gene delivery systems has been reported. Recently, polyelectrolyte multilayers built up using the ionenes as...

Step Numbering and Highlighting Phosphate Groups1. Number the steps 1-10 (at each arrow). 2. Highlight the phosphate groups, including in ATP and ADP. 3. Give a label to each reaction type (as seen by the organic substrate). De/phosphorylation (phosphate transfer), Isomerization, Oxidation, Dehydration, Cleavage 4. At which step is the glucose molecule broken into two molecules? 5. How many ATP are used, and at which steps are they used? How ...

Introduction and PlanningIntroduction Mini journal focusing on chemical kinetics and reaction order. This type of learning environment is a more authentic approach and similar to the upper chemistry course setting. The reaction that you will be working with is hydrogen peroxide and iodide ion in an acidic environment, in the presence of thiosulfate ion and starch indicator as shown in Figure 1. Iodideion is oxidized by hydrogen peroxide to ...

Calculating Coordination and Radius Ratio for Galena1. The images below show the unit cells for two minerals: galena (PbS) and fluorite (CaF2). Versions of the unit cells can be viewed interactively on the web using theAmerican Mineralogist Crystal Structure Database (AMCSD): The galena unit cell from AMCSD is the one shown below, but the fluorite version is a different one. The fluorite image below actually shows two unit cells, whereas the v...
