Predict which solvent will dissolve more of the given solute: input just the number of the solvent, so either 1 or 2 A. potassium chloride in ethanol (CH3CH2OH) (1) or 1-heptanol (C7H15OH) (2) B. ethanol (CH3CH2OH) in water (1) or hexane (CH3(CH2)4CH3) (2) C. chloromethane (CH3Cl) in chloroform (CHCl3) (1) or in methanol (CH3OH) (2)

An alcohol thermometer makes use of alcohol's changing in order to measure temperature. as the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.

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 .
