ASSIGNMENT Given in each item is a reaction scheme showing the reactant/s, reagent/s, and major product. If the compound shown at the right side is not the major product, rewrite the scheme to show the correct product/s. Propose a feasible mechanism for each reaction. Observe the proper construction of reaction mechanisms (arrow positioning, types of […]

Explain how does the presence of lone (unshared) electrons change the electronic shape in the formation of the molecular shape?
In Discussion 3, describe the role of intermolecular forces in electronic and molecular shapes. How does the presence of lone (unshared) electrons change the electronic shape in the formation of the molecular shape? Be sure to cite specific examples of this phenomenon on molecules from the VSEPR section of the text, Bb Lab and/or Worksheet. […]
Create a table of the Element’s “Normal” and “Radioactive” isotope. Describe atomic symbol, atomic number, number of protons, number of electrons, mass number, number of electrons, Mass of Isotope (amu) and Percent Abundance.
Chemistry and measurement Create an “Introduction” section. In the first paragraph of this introduction, briefly describe the purpose of this assignment. Conduct some research and write a brief paragraph(s) that addresses each of the following questions (again, in your own words, and label your paragraphs with the below lettering): What is natural radioactivity? Discuss the […]
