What is the geometric structure of the water molecule? How many pairs of valence electrons are there on the oxygen atom in the water molecule? I know oxygen has 6 valence electrons (since it is in group 6 on the periodic table), but would it have 8 (4 pai...

Show how Boyle's law can be derived from the ideal gas law.

At what temperature does a 16.3 g of nitrogen gas have a pressure of 1.25 atm in a 25.0-L tank? Plz show me step by step how to do this, with using pressure as atm.

A mixture contains 5.00 g each of O2, N2, CO2, and Ne gas. Calculate the volume of this mixture at STP. Calculate the partial pressure of each gas in the mixture at STP.

A mixture contains 5.00 g each of O2, N2, CO2, and Ne gas. Calculate the volume of this mixture at STP. Calculate the partial pressure of each gas in the mixture at STP. How do you calculate the mole fraction of each gas?

Why does decreasing the volume of a gas cause nonideal behavior?

How does the mass of the air compare to the mass of the water?

Okay, my teacher showed me in class this container. It had a balloon in the shape of a hand attached to the rim of the jar and hanging upside down. There was little drops of water in the jar, and my teacher said this was a good observation. She told me to...

So HCL would be the limiting reactant, right? And NH3 is present in excess. So do I convert 0.218 mol HCl to grams of NH4Cl? Thanks btw for helping me. :)
