Starting with the ideal gas law equation (pv - nrt), justify in steps how it can be expressed as p dgh (where d is density of the liquid in the tube, g is the acceleration of gravity at the surface of earth, and h is the height of the liquid in the column). this is a useful equation when measuring pressures with manometers and barometers

Two models of the same compound are shown. in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three-dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not
