12.0 moles of gas are in a 3.00L tank at 22.7C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a=2.300L^2*atm/mol^2 and b=0.0430 L/mol.
The oxygen atom with its 2s orbital forms a s bond with one of the three sp2 hybrid orbitals of the carbon atom; the two hydrogen atoms with their 1s orbitals each form a s bond with one of the three sp2 hybrid orbitals of the carbon atom.
Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below. HCl is a stronger acid than H2S because Cl is more electronegative than S.
