LARN 117 C30D1 Start the following in class: 1. The required focus topics, J117, for today is Explain what is meant by saying that two variables are directly proportional to one another.  Give and example of such variation from mathematics class. Explain what is meant by saying that two variables are inversely proportional to one another.  Give an example of such variation from mathematics class. State Charles' law in its simplest algebraic form. Explain how the equation for Charles' law in its simplest algebraic form shows whether the relationship between the variables in Charles' law are directly or inversely proportional. State Boyle's law in its simplest algebraic form. Explain how the equation for Boyles' law in its simplest algebraic form shows whether the relationship between the variables in Boyle's law are directly or inversely proportional. Compare and contrast Charles' Law to Boyle's Law. 2.a. Use the PQ5R or SQ5R method to prepare study guide for text section 14.3 on Ideal Gases or go to https://socratic.org/chemistry  to...

LARN 116 C29D4 Start the following in class: 1. The required focus question, J116, for today is a. An ideal gas is one that would obey all the gas laws at every temperature and pressure. To do so such a gas would have to be composed of point molecules which continually undergo random elastic collisions with each other, experience no attractive forces for each other, and sweep out all the volume occupied by the gas by virtue of their motion. Such an ideal gas exists only in the minds of thinkers such as ourselves.  In full, intelligible sentences, explain why no real gas always behaves ideally. b. Under what condition of temperature (high or low absolute temperature) would the predicted behavior of the ideal gas and the actual behavior of real gases differ most greatly?  Please make your response longer than one sentence. c. Under what condition of pressure (high or low gas pressure) would the predicted behavior of the ideal gas and the actual behavior...

LARN 115 C29D3 Start the following in class: 1.  Type the prelaboratory materials for the U10-1M Pressure-Volume Behavior of a Sample of Air laboratory investigation. Read the first part of the document through page 5 and focus on understanding the purpose of the investigation and how that purpose is to be achieved.  Type in appropriate safety considerations, save your version of the electronic document, print off the first five (5) pages of the investigation, and bring them to class. 2. Read pages R32 and R33 on the properties and uses of halogens a.k.a. Group 17 (7A) elements.  In your learning journal record the answers to these two numbered questions, J115A: What is the most interesting fact you read about?  Please make your answer to this question longer than one sentence. What makes this so interesting to you?  Please make your answer to this question longer than one sentence. What is one use for a halogen that you either were not familiar with or...
