Photochromic sunglasses, which darken when exposed to light, contain a small amount of colorless AgCl embedded in the glass. When irradiated with light, metallic silver atoms are produced and the glass darkens: AgCl→Ag+Cl. Escape of the chlorine atoms is prevented by the rigid structure of the glass, and the reaction therefore reverses as soon as the light is removed.If 310 kJ/mol of energy is required to make the reaction proceed, what wavelength of light is necessary?
Using the "like dissolves like" rule and the chemical structure of your unknown liquid, explain its solubility/insolubility in water. Describe the type of bonding that your unknown has (covalent, polar covalent)
1. Why was excess dry ice used in step 3 of the procedure? 2. Why do gas laws use degrees Kelvin rather than degrees Celsius? 3. Were you surprised at how accurately the mass of a molecule of CO 2 could be determined With such simple equipment?
