A human eye is a convex lens. In normal eyesight, the image of an object in front of our eyes is formed exactly on the retina and is inverted. In farsighted and nearsighted eyesight, where is the image formed? Which lens can be use as a corrective measure in each case? You may use online or other resources to help you answer this question. Be sure to record your research sources in the References section near the end of this document.

A 20.00 mL sample of the standard KHP (KHC8H4O4) solution requires 24.16 mL of your base to reach the end point. Write the equation for the reaction.
Calculate the molarity of a solution of glycerol made by dissolving 46.000 mL glycerol at 15 ^circ {rm C} in enough water to make 400.00 mL of solution.
(a) What are Q and ?rG for the initial reaction mixture? Q = ; ?rG = kJ mol-1 (b) Is there spontaneous reaction to the left or to the right?
An experiment requires 45.8 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
