Calculate the molar volume of saturated liquid and the molar volume of saturated vapor by the Redlich/Kwong and the Peng/Robinson equation for the following compounds and compare results with values found by suitable generalized correlations. a) Propane at 70°C where Psat = 25.94 bar. b) Isobutane at 120°C where Psat = 28.53 bar.

How many grams of mgbr2 are needed to produce 75g or metal?

What is one real world example of a colligative property?

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
