Assume that the wet limestone process requires 1 metric ton of CaCO3 to remove 90% of the sulfer from 4 metric tons of coel containing 2% S. Assume that the sulfur product is CaSO4. Calculate the percentage of the limestone converted to calcium sulfate.
Acetylene gas (C2H2) is produced as a result of the reaction CaC2(s) + 2 H2O(l) → C2H2(g) + Ca(OH)2(aq).
