QUESTION 5 If 3.3 moles of Al and 2.5 moles of Fe2O3 are allowed to react, what is the maximum number of moles of Al2O3 that can
be produced?
2A1 + Fe2O3 - Al2O3 + 2Fe

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)

Ok where is the image ?

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
