LARN 174 C44D2  [170]

The End-of-Year Examination will cover the whole year but focus on concepts and skills taught with chapters 11 through 20.   Parts I and II of the End of Year Examination, the Open Ended Response and the Selected Response sections, will be given during the time slots assigned to your class by the MNHS Final Exam Schedule. See LARN 169 for more information.

Start the following in class:

1.a. As part of your preparation for the End-of-Year Examination, review the study guides at the end of chapters one through twenty in your text together with the Honors Chemistry Topics study guide packets passed out for the mid-year and end of year examinations. If lost or misplaced, these documents are available online on your MNSD Google drive > Student Resources  > Handouts  > LARN 082.1 Mid-Year Review and MNSD Google drive > Student Resources  > Handouts  > LARN 170 End of Year Review.

1.b.  Study the vocabulary sheet, section reviews, and formative tests checked in green ink for each of the texts chapters, along with your listings of conversion ratios.

1.c.  As part of your review for the End-of-Year Examination you are required to do end of chapter problems E20-71 through E20-86 on page 660 of your text.

INSTRUCTIONS:

  • For each problem to be done that requires calculation, show the quantity and units of what you are looking for, the quantity and units of what is given, and any conversion ratios or comparison ratios needed. Circle or box in your answer reported to at least three significant figures along with the appropriate unit of measure.
  • If an algebraic formula is to be used to solve a problem, besides listing the formula and substituting in quantities and their units, show how to isolate the unknown variable on the left side of the equation, and report your answer including its units on the right side of the equation. Circle or box in your answer reported to at least three significant figures along with the appropriate unit of measure.
  • If the problem does not require a calculation, fully explain your response in legibly written or typed full sentences.

2.  Erase any stray pencil marks made in your text or texts signed out to you during the course of this school year and white out any ink marks. Then bring in the text tomorrow for inspection and a number check.  Any book in unusable condition will have to be replaced at full replacement cost according to the School Board policy on text book usage.  Keep your book available for when you study for your End-of-Year Examination.  The book itself will not be collected until the last day of this school year.

Recommended for those who have time left in their 45 minute study period, but not required of all:

  1. How do the properties of covalent molecular substances with hydrogen bonding typically differ from those covalent molecular substances that form molecules whose van der Waals attractive forces only weakly attract other molecules?
  2. Think about the sixteen properties of covalent molecular substances listed on the Properties to be understood worksheet describing differences in the properties of metals, ionic compounds, covalent network solids, and covalent molecular compounds.  Continue to study this handout for understanding and review how the typical properties of members of these classes of compounds depend on whether the compound has localized or delocalized electrons, and upon whether strong metallic, ionic, or covalent bonding or weak van der Waals forces of attraction are predominant between representative particles of the substances.  Try to understand how each property of a given covalent molecular substance is related to the groups of covalently bonded atoms that form molecules whose van der Waals attractive forces only weakly attract other molecules.

NOT ASSIGNED THIS YEAR:

Reminder:  Starting in September all students keep a listing of the any demonstration performed in class that is named on the Hands On Chemistry Demonstration Lesson document that is available to students who wish to prepare a demonstration lesson for their classmates.  This listing serves as the Table of Contents for the student recorded notes on each demonstration that later will be submitted as a report.  At the end of the school year, after the class’ last student demonstration has been performed, the assemblage of Table of Contents page and demonstration notes should be checked over before submission for grading.  Factors influencing the report grade include

  1. careful adherence to the format and procedures described below,
  2. the quantity demonstrations that were participated in by taking notes, and
  3. the quality of the notes that were recorded.
  • As the demonstrations were performed, the demonstration name should have been entered onto a Table of Contents type of listing with the sequential number of the demonstration, demonstration title, and page reference(s).
  • The student hand in number enclosed in a circle followed by name or initials in ink should be written in the upper right corner of each upward facing page.
  • The number each demonstration as listed in the Table of Contents should be written in purple ink inside a square box drawn below the first name in the right hand corner white space at the top of each note page including each page of any handout that is included as part of the notes.
  • The word missing should be written in purple ink on the Table of Contents page after the name of any demonstration that was missed and was not made up.
  • After note taking on the last student demonstration has been finished, the demonstration notes should be sequentially arranged from number 1 onward and the Table of Contents page placed on top.
  • The upper left corner of the papers should be squared off and stapled or otherwise securely fastened together.
  • The packet should be turned in for grading when all these steps have been completed, but in no case later than one week before the last day of the last marking period.
