Problem: Acetylene gas, C2H2(g), can be prepared by the reaction of calcium carbide with water: CaC2(s) + 2 H2O(l) → Ca(OH)2(s) + C2H2(g)Calculate the volume of C2H2 that is collected over water at 23 oC by reaction of 1.53 g of CaC2 if the total pressure of the gas is 753 torr. (The vapor pressure of water is 21.07 torr.)

🤓 Based on our data, we think this question is relevant for Professor Petrovich's class at NCSU.

FREE Expert Solution
  • To calculate for the V of C2H, we have to find the moles of C2H2 using the balanced reaction with mass of CaCwhich is at 1.53 g
  • Volume of C2Hcan be solved using the ideal gas equation and the conditions for temperature and pressure when we already have the moles of C2H2

Problem Details

Acetylene gas, C2H2(g), can be prepared by the reaction of calcium carbide with water:

 CaC2(s) + 2 H2O(l) → Ca(OH)2(s) + C2H2(g)

Calculate the volume of C2H2 that is collected over water at 23 oC by reaction of 1.53 g of CaC2 if the total pressure of the gas is 753 torr. (The vapor pressure of water is 21.07 torr.)
