Analysis of water in a sediment sample at equilibrium at ph 7.00 showed [so42-] = 2.00 x 10^-5 m and a partial pressure of h2s of 0.100 atm. show with appropriate calculations if methane, ch4, would be expected in the sediment.
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.
