What is the angular momentum quantum number (l) for the orbital from which a Mg atom loses two electrons from a Mg2+ ion?
0. The angular momentum quatum number l is the quantum number that dicates “shape” of orbital. It is the number of angular nodes present in the orbital. The electrons lost by magnesium when it ionizes to form a dication are 3s electrions. This orbital is characterized by having no angular nodes. 
At what volume does an ideal gas occupy at STP?
volume of an ideal gas formed from a reaction. eq.
V = n x 22.4 L
According to the Ideal Gas law, what is the relationship between moles and pressure?
As one increases, so does the other. the gas that will exert the most pressure is one that has the most molecules (moles).
