Homework 5-8 modern chemistry

All constants, equilibrium and otherwise, used in the test are taken from the values given in the Baird and Cann textbook.

You are not to collaborate with others in answering the questions. We cannot offer hints on how to work the problems.

Environmental Chemistry

In an in-class test. Like all proctors, we can clarify what is being asked in a question, but not how to answer it.

Because of the modern number of students enrolled in the Chemistry web courses, it is very difficult to homework student inquiries concerning content, etc during the last two-three weeks of the chemistry.

We will try 5-8 best to answer all content inquiries within 7 business days, but it may not be possible during the last two-three weeks of the term.

Please plan on doing your work as soon as possible. A note about procrastination.

Procrastination can be a big problem in this course. We are asked to do the tests in Blackboard 9.

It will occasionally lock up and the only practical way to cure the problem is to log out and log in some time later. Similar comments apply about computer problems on your end, illness, etc.

Conceptual Answer The interaction of a sodium ion and an oxide ion. The electrostatic attraction energy between ions of opposite charge is directly proportional to the charge on each ion Q1 and Q2 in Equation 9.

Thus, more energy is released as the charge on the ions increases assuming the internuclear distance does not increase substantially. How many grams of gaseous MgCl2 are needed to give the same electrostatic attractive energy as 0.

Calculate the magnitude of the electrostatic attractive energy E, in kilojoules for The observed internuclear distance in the gas phase is What is the electrostatic attractive energy E, in kilojoules for g of gaseous HgI2? The internuclear distance is Numerical Answers According to Equation 9.

They are part of period 6. The Actinides actinides - definition They are part of period 7.

Lanthanides and actinides are at the bottom to save space. They would normally fit between groups 3 and 4. Periodicity Figure page The differences in atomic numbers for the two groups follow the same pattern: The key is looking for the patterns.

Electron Configuration and the Periodic Table Group 18 - octet - stable Configuration of valence electrons determines the atom's chemical properties. Period and Blocks on the Periodic Table Vertical columns group or family have similar chemical properties.

Horizontal rows are series or periods. Length of each period is determined by the number of electrons that can occupy the sublevels being filled in that period. The s Block Elements:
