Which of the following best describes the valence-electron configuration of the group 3A elements?

Diborane

The chemical formula for diborane is B2H6. Each of the boron atoms in a diborane molecule is sp3 hybridized, but they are not connected to each other, only to hydrogen atoms. Two of the hydrogen atoms in diborane take on an unusual bonding arrangement in which they form two bonds each in a cyclic B−H−B−H ring. The other four hydrogen atoms have the typical bonding arrangement of one bond each.

Part C

Draw a diborane molecule.

Click the button labeled More to bring up the periodic table, or double click on an existing atom and type the symbol B to create a boron atom.

Draw the molecule by placing atoms on the grid and connecting them with bonds.

Lab 1: Creating a Database Design (Wk 3) – OR – Draw with pencil and paper diagram (take photo of it and submit) along with a summary of the diagram you prepared in a Word document. 

This assignment contains two (2) Sections: Database Design Diagram and Design Summary. You must submit both sections as a Word Document in order to complete this assignment.

Use the scenario from Assignment 1: Business Rules and Data Models to complete the lab:

Suppose a local college has tasked you to develop a database that will keep track of students and the courses that they have taken. In addition to tracking the students and courses, the client wants the database to keep track of the instructors teaching each of the courses.

Section 1: Database Design Diagram

(Using Microsoft Visio is optional; you may also use any other application you know or even draw the diagram with pen and paper and take a picture of it for submission.

1. Create a database diagram with the entities and attributes that the scenario identified (i.e., a college tracking students, courses, and instructors).
2. Submit your diagram as a Microsoft Word file.

Section 2: Design Summary

(Microsoft Word or equivalent)

1. Write a one (1) page paper in which you:
2. Discuss the degree to which you believe your diagram reflects the database design. 

Section 2 of your assignment must follow these formatting requirements:

• Submit the design summary as a Microsoft Word file.
• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page is not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

• Describe the role of databases and database management systems in managing organizational data and information.
• Compose conceptual data modeling techniques to capture the information requirements.
• Use technology and information resources to research issues in database systems.
• Write clearly and concisely about relational database management systems using proper writing mechanics and technical style conventions.

Which of the following provides the greatest annual interest?

10% compounded annually

9.5% compounded monthly

9% compounded quarterly

8.5% compounded daily

8.6% compounded continuously

According to the Washington Post: “More than three years after Nevada rancher Cliven Bundy and hundreds of militiamen faced off with federal law enforcement officers who had repossessed Bundy’s cattle, the 71-year-old is finally seeing his battle reach a courtroom.

The Bundy family has been at the center of a long-running dispute with federal authorities over the use of public lands to graze cattle, and Bundy gathered with militia members from around the country in April 2014 to directly challenge the federal government. Wearing camouflage and flak jackets and carrying semiautomatic rifles, they amassed in a dusty, washed-out canyon beneath the overpasses of Interstate 15, where two dozen federal officers had corralled Bundy’s cattle after he refused to pay years of grazing fees.”

Pick a position, for or against Bundy, and use the critical reasoning approach to close the logical gaps. So either connect evidence with conclusions in a better way to make conclusions stronger (Strengthen the evidence with new information) OR use the logical gaps to weaken an argument :

-Point out an obvious reason for the illogical conclusion 

-Enumerate a wrong generalization 

-Point out improper comparisons between two scenarios that the author assumed
