Chemistry resources include a current Chemistry Course Calendar , chapter notes, worksheets, review sheets, and labs for Chemistry. I have posted web versions of my PowerPoint presentations , which can be viewed as Flash movies within your browser or downloaded for offline viewing in the new .ppsx format. I also have my own Interactive Practice Activities . Reviews and links to some of my favorite chemistry related freeware can be found on the Chemistry Freeware page. You can select and print a periodic table on the Printable Periodic Tables page. Several years ago I produced some Problem Solving Videos for common problem types in this course. I have a collection of Programs for the TI-83plus graphing calculator, most of which I have written myself, for solving various types of Chemistry problems. These also work on the TI-84 and TI-84plus.
Col. 1 Product Name and concentration in parts-per-million (ppm) on label.
Col. 2 Particle surface area= value from lab report.
Col. 3 Efficiency Index = Divide column 2 by total ppm value from the lab report and multiply by 1000.
Col. 4 Price Cents/mL = Divide product price ($/oz) by and multiply by 100.
Col. 5 Price Cents/cm 2 = Divide 1 by column 2 and multiply by column 4.
Col. 6 mL of product required for a constant particle surface area.
Normalized value is calculated by dividing the largest column 2 value () by column 2.
Col. 7 cm 2 /$ = Divide 1 by column 5 and multiply by 100. Percent of Metal Content Table
Clean up processes were regulated by the EPA as of 2007.  The Methamphetamine Remediation Research Act of 2007 required EPA to develop guidelines for remediation of former methamphetamine labs. This creates guidelines for States and local agencies to improve "our national understanding of identifying the point at which former methamphetamine laboratories become clean enough to inhabit again." The legislation also required that EPA periodically update the guidelines, as appropriate, to reflect the best available knowledge and research.
