Determine the grams of sodium carbonate required to precipitate magnesium ions from water used in one wash cycle of a washing machine. Notes: 1) Assume the concentration of Mg+2 is 165mg/L 2) Estimate the volume of water used in your wash cycle 3)..
Calculate the pressure difference between CH4 and an ideal gas under these conditions. The van der Waals constants for CH 4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
Gaseous NOBr is placed in a closed container at -180 oC, where it partially decomposes to NO and Br2: 2 NOBr(g) 2 NO(g) + 1 Br2(g) At equilibrium it is found that p(NOBr) = 0.008230 atm, p(NO) = 0.004080 atm, and p(Br2) = 0.004130 atm.
