a light bulb converts electrical energy into light energy and also some thermal energy. the amount of electrical energy is 50 joules before the conversions.
what is the total amount of energy from before the conversions to after the conversions?
45 joules because some energy is lost when it is put off as heat.
100 joules because you start with one form of energy and end up with two forms, so the amount of energy doubles.
50 joules because as energy converts from one form to another, it cannot be created or destroyed during the conversion.
55 joules because as more electricity comes in to the light bulb, the joules increase.

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.
