LARN 131 C33D3
Start the following in class:
1.a. Use the PQ5R or SQ5R method to prepare study guide for text section 16.4 on Calculations Involving Colligative Properties or go to https://socratic.org/chemistry to research the topics brought up in section 16.4 of your text. Read section 16.4 in your chemistry text, pages 491 through 498, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 16 vocabulary list that was distributed as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake. .
1.b. Writing in blue or black ink, place your hand in number in a circle followed by your name in the upper right white space of a piece of three holed composition paper that hasn't been written...
LARN 130 C33D2
Start the following in class:
1.a. The required focus topic, J130A, for today is:
You have a job as a laboratory technician. Describe what must be done to prepare 175.0 mL of a 0.250 M CuSO4 aqueous solution. You will need to use the copper (II ) sulfate pentahydrate, CuSO4•5H2O(s), found in the stockroom to prepare the solution.
Describe what size volumetric flask that you would use and explain the reason for your selection.
Show the calculation of the number of moles of CuSO4•5H2O(s) that must be measured into the volumetric flask that you selected to use. Label all units and show cancellation of units for this calculation.
Show the calculation of the number of grams of CuSO4•5H2O(s) that must be measured into the volumetric flask that you selected to use. Label all units and show cancellation of units for this calculation.
Describe the steps needed to prepare the 0.250 M CuSO4(aq) solution starting with the quantitative transfer of the calculated...
