What is the balanced chemical equation for the reaction used to calculate ΔH∘fΔHf∘ of BaCO3(s)BaCO3(s)? If fractional coefficients are required, enter them as a fraction (i. e. 1/3). Indicate the physical states using the abbreviation (ss), (ll), or (gg) for solid, liquid, or gas, respectively without indicating allotropes. Use (aqaq) for aqueous solution.

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 .
