Students will work within their assigned group to determine the empirical formula by experimentation using a specified amount of a metal (magnesium) as it undergoes combustion. Students will collect the necessary data using a 12-cm ribbon of magnesium, a crucible … Continue reading →

Since Monday, the 25th of March, will be a review day, students are to bring any pertinent questions to class for clarification as we will be having a test on Tuesday on determining percent composition of elements in a compound, … Continue reading →

We will further continue our discussion of the empirical formula by using such a formula to determine the molecular formula of a compound as the experimental molar mass value of the compound is compared to the mass value of the … Continue reading →

Students are to practice upon determining the empirical formula of various chemical compounds as further reinforcement of said topic. They are to practice on problems #’s 161, 164, and 167 on pages 360-361.

Students are to complete any remaining problems on page 344, # 54-57. Furthermore students are to do #161 on page 360, and #172 and #173 on page 361.

Students will learn how to determine the percent composition of an element in a compound from a given set of data so that we can segue into our discussion and determination of an empirical formula for a compound through a … Continue reading →

Students will be evaluated upon molar conversions in terms of being able to demonstrate their abilities that they can convert moles to particles and vice versa as well as moles to grams and vice versa. As a reminder, students need … Continue reading →

Students who feel the need for further practice on molar mass conversions for compounds are to do page 336, #’s: 37, 38, and 39. Also, they are to do page 337, #’s: 40 and 41.

Students are to practice upon the molar conversions in their handouts, moles to mass and vice versa, through the use of chemical compounds in addition to elements that we have discussed and reinforced in class and at home.
