Start 2nd Semester: Formula Stoichiometry

Unit Goal: SWBAT make conversions between moles and volume, mass, and particles, while determine percent composition of compounds.

Wednesday: SWBAT make conversions between mass, moles, and particles.
1.) Complete Three Molar Mass Problems as a Class. Review formula, name, ionic or covalent, sharing electrons vs. transferring electrons.
Carbon Dioxide
Magnesium Fluoride
Calcium Chloride
2.) Amounts of substances throughout the room (masses of water, volumes of balloons, masses of salt, masses of soybean oil, masses of magnesium sulfate, masses of iron pyrite, masses of sugar, masses of glycerin, mass of coal)
3.) Students determine name, formula, molar mass, # of moles, and number of particles for each station.

Tuesday: SWBAT make conversions between moles, mass, volumes (at STP), and particles.
1.) 2 molar mass and naming review problems.
Vocabulary: STP, Avogadro's Number, Mole, Molar Mass, Molar Volume
2.) Volumes of gases around the room (beakers assume are filled with nitrogen, oxygen, helium, carbon dioxide, and syringes assumed to be filled with nitrogen, oxygen, helium, carbon dioxide.
3.) Students are given the volume and must determine the molar mass, moles, mass, and particles in each sample.

Thursday: SWBAT make conversions between moles, mass, volumes (at STP), and particles.
-Review problems for molar conversions (wksht.)
-CALM Worktime

Monday
-Review Mole Map: Simplified.
-Atoms in a compound review.
-CALM Problem work

Tuesday
-Samples throughout the room for percent composition problems. (water, salt, sugar, magnesium sulfate, other minerals)
-Given a formula determine the percent composition and the amount of each element in each sample.

Thursday: SWBAT make conversions between moles, mass, volumes (at STP), and particles.
Empirical Formula calculations.
CALM Problems
Students are given either an empirical formula or a percent composition and determine the vice versa.
CALM Problems.

Monday:

Chemistry Survey
