Achemistry student needs 50.0 g of dimethyl sulfoxide for an experiment. by consulting the crc handbook of chemistry and physics, the student discovers that the density of dimethyl sulfoxide is 1.10 g×10^-3. calculate the volume of dimethyl sulfoxide the student should pour out

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 .
