What is the maximum number of moles of al2o3 that can be produced by the reaction of 0. 40 mol of al with 0. 40 mol of o2 ?.

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)

Ido not understand.
