I REALLY need help with this one... A weather balloon is filled with 60.0 L of hydrogen gas at sea level pressure (101.3 kPa). It then rises to 900 m above Earth’s surface. The atmosphere at this altitude is 90.6 kPa. What is the volume of the balloon at this altitude? Assume there is no change in temperature or amount of gas.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
