Is flotation a physical change or chemical change?
Flotation is a physical change. It involves changing the density or buoyancy of an object in a liquid to make it float or sink. There is no chemical reaction taking place during flotation.
Why look for black precipitate in the butt instead of on the surface of an H2S test?
The black precipitate usually sink to the bottom which the reaction took place in. The reaction takes place at the bottom because it only occurs under anaerobic conditions, and it does not sink to the bottom as it only occurs at the bottom, not around oxygen at the top of the tube.

They go down the drain or they react with the plastic and metal and could ruin the pipes.

Can drano be used in a dishwasher?
I strongly advise against using drano. The drain line from the dishwasher to the garbage disposal is pretty short. Try running your dishwasher and fill up your sink, when your dishwasher starts to drain, pull the plug on the sink and start your garbage disposal. You may be able to get away with using Drano a few times, but the thin plastic tube will be made brittle and possibly break in the future, also you will want to run it empty a few times if you do use a chemical. Odds are the clog is at the drain and you have some clearly nasty junk clogging it that will require some manual work. I recommend cutting up a coat hanger and bending a small hook on the end to clean it out. There could be other electrical / mechanical issues with your dishwasher, you may want to have a trusted service technician take a look.
