Description I am significantly struggling within my chemistry class. I have been doing the readings and watching youtube videos but the questions still illude me. I am currently behind on homework and am looking for assistance in answering these problems. There are 20 some of them require calculations and others just explainations. Any assistance would be helpful. Thank you!
Description I have chemistry homework due and I need at least a 90%. You will find the questions down in the attachment below they are multiple choice so make sure your answer goes with one of the choices.
Description Please refer to the periodic table to help with your answer (no other resources may be used for this exam).Locate the following elements on the periodic table:magnesium, nitrogen and oxygen. What monatomic ion would each of these elements form?Based on valence electrons, explain why these elements would form the ion you listed. Write the formula of one polyatomic ion that could be formed from these elements.Make sure to include the ion charge. Given what you have learned from the unit so far about chemical bonding, describe and give the formulas for at least three ionic compounds that the ions would listed above would produce together
Description I am completing a lab at home where I had to make a PH indicator solution out of a liquid made from boiling red cabbage leaves. I added 15 drops of the PH indicator solution to 1 Tablespoon the various substances below in the chart. The salt, vegetable oil, ginger ale and baking soda were made by adding 1 tsp of those substances to 1 tablespoon of distilled water. Those instructions and ph ranges were provided in the lab instructions. Chemistry is NOT my subject and now I am stumped trying to figure out how to complete the remainder of the chart for the lab. The chart is below. Substance color of solution without indicator color of solution with indicator pH [H+] pOH [OH-] Solution #1 rubbing alcohol clear lilac 5 - 6 Solution #2 vinegar clear cherry red 2 Solution #3 baking soda white blue 8 - 9 Solution #4 ginger ale clear lilac 5- 6 Solution #5 vegetable oil clear lilac 5 - 6 Solution #6 salt clear cloudy blue 8 - 9
Description Please answer each questions with a few sentences explaining the answer. These are essay review questions. 1. Use the information for the isotopes of element X to calculate the average atomic mass of X, and identify the element. (Please see attached document to see the chart that goes with this question) 2. Cynthia and Jackie both draw the Lewis structure for F2 as shown below. Which drawing is correct? Explain. Cynthia's Drawing Jackie's Drawing 3. Which functional groups are involved in an amino acid?
