POWER POINT: STOICHIOMETRY OF FLUIDS

Students: HERE are the Power Point Notes on 'Stoichiometry of Fluids' given in the first two weeks of Unit 4, the final unit of the Fall semester in Mr. Hatfield's Chemistry classes.   



This section of notes covers problems having to do with molar volumes of gases, limiting reactants and percent yield, molar concentrations and other properties of solutions.   A Study Guide based on these notes is available HERE in PDF form.

VIDEO: SOLUTIONS

Students can watch Paul Andersen's discussion of solutions and their properties as many times as needed here, on-line, in the video embedded below:




Students can also access the PDF version of the worksheet given in class, based on this video, HERE.

SYLLABUS, UNIT 4

This is the FINAL Unit of the Fall 2017 semester in Mr. Hatfield's Chemistry classes.  Major topics include:  reviewing past lessons on stoichiometry, applying stoichiometric principles to new problems involving fluids (liquids and gases) and introducing the rate of reactions.

POWER POINT: THE MOLE

Students, you can find the latest Power Point Notes on Chemical Quantities and Moles HERE:




This comes at the end of four days of instruction, beginning on Tuesday the 17th, in which students were given examples of and practiced solving problems in which students do calculations with moles. 

At the end of Wednesday's lesson, they were given a Homework assignment, "Calculations With Moles." That item is available HERE.

STUDY HALL will occur Tuesday 10/24-Thursday 10/26 during lunch next week.     Students who have been assigned STUDY HALL must attend, or they will be treated as defiant.

Unit 3 began on Monday the 16th.  A new syllabus for that unit will be made available on Wednesday the 18th.
