Start the following in class:

1.  In your Journal Notebook write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper.  In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name.  To the left of the marginal line, print J76A and circle it. Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement. The required journal focus question J76A for today is

  1. An Arrhenius base is often the water solution of an ionically bonded molecule that when placed in contact with water, produces OH–(aq) ions as the only negatively charged ions.   How are these bases named?
  2. Add this note to your journal: Nitrogen containing covalently bonded compounds containing a nonbonding pair of electrons (such as ammonia, :NH3) can to some small degree interact with water by attracting a proton from one of the hydrogen atoms in the water molecule thus forming an ammonium cation, NH4+, and leaving an aqueous hydroxide ion behind.  These bases can be named as aqueous solutions of the given compound.  For instance, NH3(aq), is aqueous ammonia.

2.  If you have not yet finished it in class, finish doing the Section Review packet for chapter 9 as a formative assessment to find out some of the things that you do and do not know, and not as a research project.

  • If you did not obtain a section review packet for the chapter in class or if you have misplaced it, go to MNSD Google Drive > Student Resources > Section Reviews and print off a section review for each individual section of the chapter.
  • The section review packet for each chapter contains a separate section review document for each section of the chapter.  So for example, a chapter with four sections would have four separate section review documents that need to be printed off.  Each section review question document is identified by a name whose last two digits or last three digits represent the chapter number followed by the section number of that particular section.
  • For each question or problem challenge, either answer the question to the best of your ability using one or more full sentences, or answer the problem to the best of your ability by recording any numbers and units together with the mathematical operations performed in symbolic terms, along with the solution to the problem which should be circled.
  • This is an important assignment. Be sure to finish this packet in its entirety.
  • After doing the section review packet, but before you demonstrate your understanding on our class’ chapter test, you will check all your responses using green ink check marks √ for each correct response, and by lining out (striking trough) and inserting improved text in green ink when you think the suggested response expresses your present understanding in a better way.  Then, when you know what you didn’t understand, you will be able to study more efficiently by studying that which you have corrected in green ink.

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

1.  In your Journal Notebook write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper.

  • In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name.
  • To the left of the marginal line, print J76B and circle it.

For your journal entry J76B, you are to construct a concept map.  Please turn to page 286 in your text and, in your learning journal, construct a concept map relating the eight terms listed at the bottom of the page.  Connect related terms with arrows such that the subject of each sentence explaining the relationship is at the tail of the arrow, the verb describing the relationship of the subject to the predicate is written beside the arrow, and the arrow head is touching the oval of the term which is the object or predicate nominative of the verb that you have chosen.
