Crown ethers solubilize ionic compounds by creating a hydrophilic binding pocket that fits a metal cation with a hydrophobic outside. Say you wanted to dissolve each of the following ionic compounds in benzene - you'd have to add the appropriate crown ether. Match each compound with the appropriate crown ether. LICI

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 .
