The Scenario Professor Ndekele asks you to check the status of reagents in an old cabinet in the lab. You find a jar labeled Ca(OH)$_2$ which contains disc-shaped white crystals. You decide to perform a titration to verify its purity. Observations You make the following essential observations: 1. You dissolve 5.00 g of the crystals from the Ca(OH)$_2$ jar in enough water to make 100.0 mL of solution. You find that there is a small amount of white solid that won't dissolve, so you separate it off by filtration. 2. You titrate three 10 mL aliquots of your solution with 1.00 M HCl(aq) and obtain the following data Trial V Ca(OH)$_2$ (mL) V$_{HCl}$(mL) 1 10.1 12.8 2 10.3 13.0 3 10.0 12.7 Analysis 1. Determine the expected concentration of the solution you made by dissolving 5.00 g of solid calcium hydroxide in enough water to make 100.0 mL of solution (this is assuming the the calcium hydroxide is not at all degraded) 2. Determine the concentration of calcium hydroxide solution for each trial in the titration, and also determine the average value for the three trials. 3. Determine the percent purity in your sample by dividing the result of question 2 by the result of question 1 and multiplying the outcome by 100. 4. Write the net ionic equation for the decomposition of solid Ca(OH)$_2$ by aqueous carbonic acid, H$_2$CO$_3$(aq) in the air. The precipitate is the solid that you had to filter off in observation 1. 5. Is the equation you wrote in question 4 an Oxidation-Reduction reaction? How do you know? 6. EXTRA CREDIT: If you were to dry the solid formed when you made your Ca(OH)$_2$ solution and weigh it, how much would you expect it to weigh?

According to Piaget, our current state of knowledge guides our processing, substantially influencing how (and what) new information is acquired. Knowing is an active, constructive process—an interaction between the environment and the active individual who updates and informs expectations based on experiences. ? True ? False QUESTION 9 Working memory involves storage capacity plus the ability to transform information held in the short-term system. ? True ? False QUESTION 10 In the study conducted by Miller, children were told to remember the location of one set of objects, either the household objects or animals. Older children who used a strategy to study the location of one set of objects, still did not perform well when they were later asked to remember the location of those items. This is an example of: A. Long-term memory B. Working memory C. Utilization deficiency D. Production deficiency
