In this station, you will find a sample of table salt; the chemical formula of table salt is NaCl. Using the balance, weigh out 6.00 g of NaCl and dissolve in 50 mL of deionized (d.i.) water. Once com-pletely dissolved, add additional d.i. water to make the final volume of solution 100.0 mL. What is the mass percent NaCl in the solution? What is the molarity of the solution

Below you will find five reaction products (labeled product 1, product 2, etc.), but you will only find four reaction schemes. Your
job is to match the reaction scheme with the correct product. Simply fill in the blank with the product number (i.e. 1,2,3,4, or
5). Then, state the regio-control that governs the reaction (i.e. Markovnikov or anti-Markovnikov). If the reaction does not have
any regio-control then enter none.

hotogray lenses incorporate small amounts of silver chloride in the glass of the lens. When light hits the AgCl particles, the following reaction occurs:
hv
AgCl Ag + Cl
The silver metal that is formed causes the lenses to darken. The enthalpy change for this reaction is 2.90 × 10² kJ/mol. Assuming all this energy must be supplied by light, what is the maximum
vavelength of light that can cause this reaction?
