Day 104

Students continued watching the Percy Julian: Forgotten Genius video.  Also, to reinforce naming and writing ionic, molecular and acid formulas, students explored the following sites and completed online practice:

Use these sites to help you practice your naming/writing skills. A note of fair warning...some examples from these sites may use ions that we have not specifically discussed (for instance, phosphite or hydrogen sulfate). Don't fear that which you have not explicitly studied...use what you KNOW about the PATTERNS we've discussed in naming and try them (you may just impress yourself!)

• http://www.kentschools.net/ccarman/cp-chemistry/compound-naming/ - This exercise allows you to choose the number of practice questions for either ionic or molecular compounds (or both) starting with either the formula or name (or both). (Note: Use "hydrogen carbonate" for HCO3- instead of "bicarbonate".)
• http://www.fernbank.edu/Chemistry/nomen.html - A simple HTML-based review of nomenclature. The material provided in yellow covers the same formula types we discussed in class (ionic, molecular & acids)
• http://www.sciencegeek.net/Chemistry/taters/Unit4BinaryNomenclature.htm - Practice with molecular compounds
