Answer to Question #112265 in General Chemistry for Gerlach

Question

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.)

Answer 1

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
