I'm doing some extra credit for scienceI need details on what to use, how to use it and what I'll get.
go for as light as possible
The egg did no longer sink simply by fact of diffusion (osmosis given which you're dealing with water)Diffusion is the place you have a close-by of decrease concentration to bigger concentration, and salt water is extra centred.
Aluminium is too reactive a metal to get any other way than by electrolysisHowever bauxite is an impure form of aluminium oxide, but has a very high melting point indeedSo the cyrolite, mentioned in another answer, is added as a flux i.e.makes it all melt at a much lower temperature Making aluminium metal is a high energy process anyway, as 3 electrons are needed to liberate one Al Al3+ plus 3e- Al For this reason Al works are often situated near sources of power eg major hydroelectric power stationsIt's not really something you can easily copy in the lab!
