Reagent grade potassium hydrogen phthalate (khp, mass 204.23g/mole) is a high molecular weight, stable, monoprotic solid acid. it is commonly used for standardizing sodium hydroxide solutions. what concentration of sodium hydroxide solution would be needed to titration 0.6000g of khp so that the volume of naoh needed is 35.00ml

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 .
