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),(9) In the second step, acetylene (C,H), carbon dioxide and water react to form acrylic acid (CH,CHCO,H): 6C,H,(g) + 3 CO2(g) + 4H,0(g) 5 CH,CHCO,H(g) Suppose the yield of the first step is 96.% and the yield of the second step is 79.%. Calculate the mass of calcium carbide required to make 2.0 kg of acrylic acid. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

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: CaC2(s) + 2H,O(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) + 3 CO2(g) + 4H,0(g) - 5 CH,CHCO,H(g) Suppose the yield of the first step is 96.% and the yield of the second step is 79.%. Calculate the mass of calcium carbide required to make 2.0 kg of acrylic acid. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.
