The normal freezing point of a certain liquid is , but when of potassium bromide () are dissolved in of the solution freezes at instead. Use this information to calculate the molal freezing point depression constant of . Round your answer to significant digits.

At room temperature what happens to the average kinetic energy of the molecules of a solid, liquid, and a gas

In pqr m< p=60 m< q= 30 and m

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 .
