Question

Calcium carbide, CaC₂ reacts with water to form ethyne, C₂H₂, and calcium hydroxide.

the equation for the reaction is shown.
CaC₂(s) + 2H₂O(l)→ C₂H₂(g) + Ca(OH)2(s)

which Volume of ethyne is produced when 6g of water react completely with calcium carbide?

A. 4dm^3
B. 8dm^3
C. 36dm^3
D. 72dm^3

( please solve explanation!! )
​

Answer 1

36dm³

Step-by-step explanation:

For this question we are required to find the volume of the ethyne which is released while reacting 6 grams of water with calcium carbide.

Here to find the volume of ethyne produced, we can find the moles of the ethyne in the reaction by using the mole concept, and then converting the mol into the volume using the formula V=nRT/p or PV=nRT (n being the moles of the gas)
