Different Rules that Dictate the Name of A Molecule Question

0 comments

Imagine you are in front of the classroom teaching a class how to do the problem set for the first time. There are many approaches of how to teach effectively. Use an ipad, whiteboard, or start with a blank page. Do not start with any pre-written material in the video.

You will be graded on:

  1. Did you introduce the topic and provide enough details and background information so that a new chemistry student can understand the steps?
  2. Was the presentation clear to follow both visually and logically and did you start the presentation without preprepared written information?
  3. Is the problem accurately explained and solved?

2) Submit a pdf of written work for the other two of the problems sets. (50%)

Present the problem set solution by answering the question while providing about a paragraph or two of written explanation on the thought process of how to solve the problem and of each step taken. Use bullet points, label individual steps, and write in complete sentences. Do not just provide the answer or solution. Without explanations accompanying EACH STEP, you will not receive full credit.

You will be graded on:

  1. Was each step in the solution clearly explained so that someone with no experience in chemistry could follow the logic?
  2. Is the problem accurately explained and solved?
  3. Problem sets
  4. Problem Set 1 Nomenclature can be a confusing topic because there are different rules that dictate the name of a molecule, depending on its type. For each compound explain the rule system used and give the chemical formulas for each of the following species. Remember, you are graded based on your EXPLANATIONS more than your answer. Do not google these, you will be graded based on the rules that we learned in class. a) nitrogen heptoxide b) oxalic acid c) copper (I) carbonate
  5. Problem Set 2 An ion, OS2H+, has the two sulfur atoms attached directly to the central oxygen atom and the hydrogen atom attached to one of the sulfur atoms. The ion has a +1 overall charge a) Draw the lewis dot structure of the ion. Explain every single step taken to get to the answer. b) Determine the electron geometry and the molecular geometry of the molecule around the central oxygen atom, and redraw the molecule with the appropriate molecular geometry. Label the bond angles on this drawing. Explain every single step taken to get to the answer. c) Is the molecule polar or nonpolar? Use partial positive and negative charges on the atoms to illustrate bond polarities. Explain every single step taken to get to the answer.
  6. Problem Set 3 A vessel containing 1.21 moles of gas occupies a volume of 3.57 liters at 1.8 atm. Gas is added to the vessel until it contains 3.00 moles and then it is moved to a low-pressure container at 739 mmHg. What is the new volume of the vessel in liters?Hint: you do not have an equation to solve this problem yet. Reviewing the “Deriving Gas Laws” section in the textbook may help (Ch 7, page 5). Explain every single step taken to get to the answer. Explain how your new law was derived.
