A water heater warms 350 g of water from a temperature of 22.7 oC to a temperature of 83.7 oC. Determine the amount of energy (in joules) required. (Use the table above for missing values)

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
