Regents Chemistry

 

This course builds from knowledge acquired in 8th grade physical science. This course prepares students for the NYS Physical Science Regents in Chemistry and for future study of chemistry at the college level. It's a great way to develop the critical thinking skills needed in all facets of life.

Describes vapor pressure of liquids and relationship to intermolecular forces and boiling points; explains how boiling points change with pressure
Outline for formal lab reports and descriptions of sections
Gas Law notes (29.7 KB)
You may find this helpful in addition to the textbook chapter 13 for understanding Kinetic Molecular Theory (KMT) and the Gas Laws. In Regents chemistry problems, the number of moles (mass) of gas is always kept constant in the problem, and we make use of Boyles Law for constant temperature problems, Charles Law for constant pressure problems, and Gay-Lussac Law for constant volume problems. It sounds complex, but each of the previous laws equations can be derived from the Combined gas law given on the back of the CRT, by simply taking out the variable that is constant in the problem. The ideal gas law is presented in your textbook, but is not tested in Regents Chemistry. It will appear in a first year college chem course.
Introduction to Atomic Theory: Understand that the atomic theory has evolved over a long period of time (thousands of years!) and continues to evolve today. Know the key scientists and the significance of their findings, as listed in the table included.
posted by request, this chart shows the properties associated with the various types of bonding and should allow you to determine type of bond can usually be figured out from just a few physical tests
shows temperature vs. heat added or removed, describes changes in potential and kinetic energies
