Lithium is the only metal that reacts with nitrogen gas at room temperature to form lithium nitride. to avoid oxide formation, the reaction is performed under pure nitrogen gas. given the experimental data in the table below, what is the empirical formula of lithium nitride? the molar mass of lithium is 6.94 g/mol and of nitrogen is 14.01 g/mol.

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 .
