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 (CaC,) and water react to form acetylene (C,H,) and calcium hydroxide: CaC, (s) + 2H,0(g) - C,H,(g) + Ca(OH), (s) In the second step, acetylene (C,H,), carbon dioxide and water react to form acrylic acid (CH,CHCO,H): 6C,H, (g) 3co,(g) + 4H,0(g) 5 CH, CHCO,H (g) Suppose the yield of the first step is 68.% and the yield of the second step is 66.%. Calculate the mass of calcium carbide required to make 10.0 kg of acrylic acid. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

determine the enthalpy change for each of the reactions: (It is necessary to draw Lewis structures so you know where there may be single, double or triple bonds)   H2 +  Br2  =  2HBr   CH4 +  I2  =  CH3I +  HI   C2H4 +  3O2  =  2CO2  +  2H2O   2C2H6 +  7O2  =  4CO2  +  6H2O
