Question

Calcium carbide (CaC2) reacts with water to produce acetylene (C2H2) :
CaC2 (s) + 2H2O (g) →Ca(OH)2 (s) + C2H2 (g). Production of 39 g of C2H2 requires
consumption of __________ g of H2O

Answer 1

Answer:

Ethyne

(

C

2

H

2

)

and calcium hydroxide are formed when calcium carbide is treated with water. The molar ratio between water and ethyne for this reaction is 2 : 1.
