Describe the formation of an aqueous solution of sodium chloride (NaCl) by placing the statements in the correct order.

1 Place these in the proper order.

Water molecules collide with the surface of an NaCl crystal.

The ions break away from the surface of the crystal.

The charged ends of water molecules attract the positive sodium ions and negative

chloride ions.

More ions on the surface

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 .
