If you reacted 88.9 g of ammonia with excess oxygen, what mass of water would you expect to make? You will need to balance the equation first.

NH3(g) + O2(g) -> NO(g) + H2O(g)
What are the energy values for each 4 quantum number?
The ''average'' speed,u, of molecules in a gas can be found using the equation u^2=3RT/M. If the units for u=cm/s, for M=g/mol and for T=K, what are the units for R?
A solvent for an insoluble chloride
4Al + 3O₂ → 2Al₂O₃
How does 4Al+3O₂ turn into 2Al₂O₃? WHat type of dividing is going on? Shouldn't it be 4Al3O₂? (the original problem was to make Al+O₂ into a balanced equation, and I understood it until that last part.) I know it has something to do with the fact that the charge of Al is +3 and the charge of O is -2 but I don't know what to do with that. Is +3 and -2 supposed to add up to something? Sorry I'm just really confused.
