wats azeotropic mixture?

2) methyl n ethyl alcohol....both are present

3) may be zn(oh)2??? but, neither of the amphoteric hydroxides are soluble, so they should actually react with ammonium hydroxide n not ammonia to form a solution...ryt? zn hydroxide reacts with excess ammonium hydroxide to form tetramine zn hydroxide solution......i dunno...this is a guess.....plz help!

4)lead as well as zinc oxide.

5) phosphorus-trichloride and pentachloride. or hydrogen-HCl and HClO.
