Chemical Bonding

/in /by

Atomic bonds form the basis for the myriad of substances that exist, as well as their internal energy, reactions,
and other characteristics. The key types of atomic bonds considered here are metallic, ionic, and covalent.
These are referred to as atomic bonds because they actually bond atoms together. However, sometimes the
term “chemical bonding” is used, but both phrases are referring to the same phenomenon – the various ways
that atoms bond together to form more complex substances. Ionic and covalent bonds are probably the most
crucial in chemistry because they can result in the formation of compounds. Ionic and covalent bonding
between different elements results in the formation of compounds because of the atoms bond together in fixed
ratios, a crucial characteristic of compounds. Metallic bonds result in the formation of alloys as opposed to
compounds because the atoms are not required to combine in fixed ratios.
As physical systems, atoms naturally seek the lowest energy state (the state of existence requiring the least
energy). Accordingly, configurations of small bound groups of atoms, called molecules, are formed. When
individual atoms are sufficiently near each other, their electric charges redistribute in such fashion as to form
attractive electric forces called bonds:

  1. covalent – sharing of electrons by two nuclei
  2. ionic – electrostatic attraction between oppositely charged ions
  3. metallic – attraction of nuclei in crystal for outer shell electrons shared among all available orbitals
  4. hydrogen – attraction between H atoms of one molecule and unshared electrons of another

  5. Read chapter 9 in Tillery (Keep in mind the summary of equations at the end of the chapter).
  6. Answer/solve any two of the following (10 pts. each):
    a. What is the difference between the formation of an ionic bond and formation of a covalent bond?
    b. What relationship, if any, exists between the number of valence electrons and the number of covalent bonds
    that the atom can form? Explain.
    c. What is the difference between a polar covalent bond and a nonpolar covalent bond?
    d. Analyze how you might know for certain that a pure substance you have is an ionic compound and not a
    covalent compound.

International versus U.S. Accounting Standards

/in /by

For this assignment, you will research and compare international and U.S. accounting standards. This will enable you to see how the different reporting methods affect business and how product costs are affected by international business.

The learning objectives of this report are as follows:

  1. Compare and contrast basic U.S. and international financial accounting standards. 2. Explain how key international factors affect business reporting.

ACC 5301, Management Applications of Accounting 3

  1. Identify key compliance and regulatory requirements.

REDOX TITRATION: Fe2+ AND Ce4+

/in /by

This Experimet is about Redox Reaction. I need to find the graph of First and second derivative Graph. once you find the First and second derivative we can used the values to solved the table. I have attached all the information our professor did step by step and also, how to find the First and second derivative graph. all you need is excel graph and some calculation to the experiment for the table. Professor want us to show her any formula we use to solve any problem especially the table is the one to do once you do the graph. for example ( 2×2+4) = 8. I need prove to her how I get 8, I will write like 2×2= 4 and 4+4 = 8 something like that. I upload the file you need. The raw data and the calculation table. Also the table for graph.
I took a green shot mack pro for the Raw data values and the table values for trial 1,2,3. I arranged them in ascending order in my screen shot. also, if you have any question let me know I have Anatomy midterm tomorrow I could not attempt this experiment. The calculation table in the experiment begins with finding the Endpoint, mL

I need graphs and tables, no introduction, please.

Army Executive Summary (EXSUM)

/in /by

Prepare a one-page EXSUM that describes the purpose and role of the General Fund Enterprise Business
System (GFEBS) in the government’s efforts to manage costs.executive summary using Arial font, 12 pitch. It
may be no longer than one page in length. UseDA Memo 25-52,Staff Action Process and Correspondence
Policies, for the format and style of an executive summary.Your office symbol is ATSG-NCOA-FMS. The G-8,
LTCBrian Clearman, is the approving official for your EXSUM.
• Use the active voice. Employ the elements of good Army writing. Don’t use a big word when a small one will
do; avoid run-on sentences.
• Do not overstate and do not overwrite. Like all military matters, do — or in this case, say — what has to be said
and move on.
• Speak to the audience of your executive summary. If your report is for high-ranking officers or NCOs, it
requires a more formal tone than if the report is to be read by privates.
• Write a thesis statement that addresses the major thrust of the executive summary. Rather than quietly
wading in, drop the bombshell and get the reader’s attention in the first sentence of the executive summary.
• Leave your executive summary for at least 24 hours and then edit it for typing and grammar mistakes. Read
the summary aloud and assess it for proper military tone.
