The diagrams show the movement of particles for two substances. The left image labeled X shows spaced out green balls with long movement lines behind them. The right image shows tightly cluster green balls with short movement lines behind them. Which best compares the temperatures of the substances?
Substance X has the highest temperature because its particles have more kinetic energy.
Substance X has the highest temperature because it has fewer particles.
Substance Y has the highest temperature because its particles have more kinetic energy.
Substance Y has the highest temperature because it has more particles.

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) β c2h2 (g) + caoh2 (s) =Ξ΄hβ414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) β 5ch2chco2h (g) =Ξ΄h132.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 .
