Over the Easter break,  students are to review and practice problem-solving on mole to mole ratios on page 375 (#11 & #12) as well as page 983 (#6 & #7).

Students will practice on mole ratio application since mole ratios show the relationships between the quantity of reactants and those of the products, i.e., stoichiometry.

Students will use their prior knowledge in learning to describe the types of relationships shown by a chemical equation and state the mole ratios from any balanced chemical reaction.

Since we have agreed on the fact that students are to be evaluated on one section at a time, we will review Chapter 10, The Mole, because it is the basis for our next chapter on stoichiometry.

A certain number of students will be given an opportunity to improve their past performance on molar coversions. Students need to practice on converting moles to particles and vice versa as well as moles to grams and vice versa.

Certain students will be evaluated again on Friday on the conversion process of changing moles to particles or grams as well as changing grams to moles or moles to particles. Therefore, today, Thursday, our review continues from yesterday, Wednesday, with further problems … Continue reading →

Students will be evaluated upon their abilities on how to calculate percent composition of the elements in a compound, empirical formula of a compound, and/or its molecular formula based upon given sets of data.

Simply Put:  Students will review as they will go up to the Promethean board and solve the assigned problems on page 982, #’s 25 through 32.

As students continue to practice upon the empirical formula, the molecular formula will be explained to enhance the process of how compounds are determined and put into practice. Students need to do or must have done by the end of Friday the … Continue reading →
