Question

ACETYLENE CAN BE PREPARED FROM CALCIUM CARBONATE BY A SERIES OF REACTIONS.THE MASS OF 80% CALCIUM CARBONATE REQUIRED TO PREPARE 2MOLES OF ACETYLENE IS?

Answer 1

Acetylene can be prepared from Calcium Carbonate by a series of chemical reactions.

The reaction is given below :

CaO + 3C → CaC2 + CO, CaC2 + 2H2O → Ca(OH)2 + C2H2,

Now, we have to calculate the mass of 80% Calcium Carbonate required to prepare 2 moles of Acetylene.The amount will be 250g.
