$ P O CHEMICAL REACTIONS Reaction sequence stoichiometry 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 (CaC₂) and water react to form acetylene (C₂H₂) and calcium hydroxide: C₂H₂(g) + Ca(OH)₂ (s) In the second step, acetylene (C₂H₂), carbon dioxide and water react to form acrylic acid (CH₂CHCO₂H): 6C₂H₂ (g) + 3C0₂(g) + 4H₂O(g) 5 CH₂CHCO₂H (g) - CaC₂ (s) + 2H₂O(g) → C₂H₂(g) Suppose the yield of the first step is 87.% and the yield of the second step is 91.%. Calculate the mass of calcium carbide required to make 8.0 kg of acrylic acid. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits. 0 Explanation % 5 T B Check 20 A 6 Y H N 0.0 0° ロ・ロ 믐 20 MacBook Pro & X 7 U 3 * 8 M I K ( 9 H V.
