Put the steps below in the order they are performed in the lab experiment by numbering them 1-7. Use a Bunsen burner to heat and dry the hydrate, repeating until the mass no longer decreases. Measure the final masses of the crucible, cover, and anhydrous salt. Compute differences in masses to find the reactants and products. Measure initial masses of the crucible and cover, with and without the hydrate. Use the numbers of moles to compute the mole ratio. Use stoichiometry to convert these masses to moles. Use the mole ratio to write the hydrate’s formula.

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 .
