Chemistry Schedule for October 17th - 21st

Monday: Students will learn to calculate the molar mass of various compounds. They will also learn to calculate mass from moles for complex compounds. Next, they will apply their application skills on solving variety of problems.

Tuesday: Isopentyl acetate is the compound responsible for the scent of bananas. Interestingly, bees release about 1 mg of this compound whey they sting. This attracts other bees, which then join the attack. Students will learn to calculate the number of isopentyl acetate molecules released in a typical sting bite. Next, we will focus on calculating the percent composition of compounds and mass percent. Students will work on several problems during class. Do the section review for homework.

Wednesday: Discussion on sec-6.3, Formulas of Compounds. Students will learn to calculate the empirical formula and the molecular formula for various compounds. They will study the tools to determine the empirical formula of a compound. Today our focus will be on calculating the empirical formulas for binary compounds.

Thursday: We will learn to calculate empirical formulas for compounds containing three or more elements and from percent composition. Students will work on several problems to get more practice.

Friday: Students will learn to calculate the molecular formulas for various compounds. They will work on various problems and then move on to the sec-6.3 section review.
