Which of these compounds would be the best conductor in the pure liquid or molten state 1- I2 2- H2S 3- AsH3 4- SiH4 5- H2Se 6- H2Te 7- BaF2 8- GeH4 9- NH3 10-Cl2?
BaF2 would be much the best electrical conductor in the list, because it is the only one that is ionically bonded. When molten, such compounds are excellent conductors.

What happens to gold when you put it in bleach?
Nothing. Gold is inert with bleach. Bleach can effect the other metals in the alloy as most gold items are not pure gold. If the piece contains silver or copper, the bleach can affect those metals.Most items we call gold are not pure gold but are mostly gold alloyed with other metals. 14k gold for example is 14 parts pure gold and 10 parts other metals ( such as silver and copper) However the gold itself is not harmed in anyway
What percent is pure silver?
For ANY substance, "pure" means complete, total, and without any other material added - i.e. 100%. The problem is that it's almost impossible to refine silver to be totally free of any other metals, but it IS practical to create what's called .999 fine silver. That means 999/1000 of the metal is pure silver and the remaining 1/10 of 1% is other metals or contaminants. For all practical purposes, that's pure silver.
