Answer to Question #112265 in General Chemistry for Gerlach

Question #112265

Calcium carbide, CaC2, is an important preliminary chemical for industries producing synthetic fabrics and plastics. CaC2 may be produced by heating calcium oxide with coke: CaO + 3C → CaC2 + CO.

What is the amount of CaC2 which can be produced from the reaction of excess calcium oxide and 10.2 g of carbon? (Assume 100% efficiency of reaction for purposes of this problem.)

Expert's answer

From 3 moles of C 1 mole of CaC2 is produced.

From 36 gm of C, 64 gm of CaC2 is produced.

Therefore, from 10.2 gm of C, CaC2 will be produced =(64/36)*10.2

=18.133 gm
