LARN 127 C32D3 Start the following in class: 1.a.  The required focus question, J127A, for today is      Some procedures affect the rate at which a given amount of solute will dissolve in a given amount of solvent and some procedures can affect the maximum amount of solute that can dissolve in a given amount of solvent at a given temperature (i.e. can affect the solubility of the solute in that solvent at that temperature). a. Describe the typical effects on the rate at which a solute dissolves, if any, of stirring or agitation of the solute and solvent mixture, increasing the temperature of the solute and solvent mixture, decreasing solute particle size before mixing it with the solvent, and increasing the partial pressure of a gaseous solute on the rate of dissolution of the solute. b. Describe the typical effects on the maximum amount of solute that can dissolve in a given amount of solvent, if any, of stirring or agitation...

LARN 111 C28D3 Start the following in class: 1. In the upper right corner white space of each upward Journal notebook facing page, write your hand in number within a circle followed by your name.  Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms.  Begin each days paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement. . The required focus topic, J111, for today is What is vapor pressure? How does the value of a substance's vapor pressure vary with temperature? Liquids typically exist in containers with a gas filling the upper portion of the container. This gas above the liquid exerts pressure on the liquid.  What is the relationship between the vapor pressure of a liquid and the measured pressure of the gas above the liquid at a given temperature in a closed system? When the vapor...
