Problem- Use the van der Waals equation of state to calculate the pressure of 2.70 mol of CH4 at 487 K in a 5.30-L vessel. Use the ideal gas equation to calculate the pressure under the same conditions.
Any expert will able to provide correct answer for the above question.
You have a 1 g/L solution of soil organic matter. The amount of fulvic acid is 2 times the amount of humic acid. You add 2 mM Cu to a final [Cu] =0.8 mM. Experiment at pH 6.5. Equation Cu2+ + 2HLi = CuLi2 + 2H+. Li = [FA]+[HA].
