As you observed liquid water forming into ice, some changes were observed? What TWO factors changed as water turns into ice. 1The motion of the molecules stopped 2The molecules slowed down, moved apart and kind of got stuck in one place but continued to vibrate.
3The average molecular speed of the water molecules decreased to zero.
4The average molecular speed of the water molecules increased
5The volume of the ice was greater than the volume of the liquid water
6The liquid water trapped the molecules in place

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 .
