Acetylene gas, C2H2(g), can be produced by reacting solid calcium carbide, CaC2, with water. The products are acetylene and calcium hydroxide. What volume of wet acetylene is collected at 25°C and 725 torr when 4.10 g calcium carbide is reacted with an excess of water? (At 25°C the vapor pressure of water is 23.8 torr.)
CaC2 + 2H2O → C2H2 + Ca(OH)2
Solve for mole C2H2 produced from 4.10 g CaC2.
4.10 g CaC2 X (1 mol CaC2 / 64 g ...
The volume, pressure, acetylene gas reacting with solid calcium cards are examined.
