# Problem: 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 (C), which is mainly carbon:CaO(s) + 3 C(s) → CaC2(s) + CO(g)What is the amount of CaC2 (molar mass = 64.1 g mol-1) which can be produced from the reaction of excess calcium oxide and 18.0 g of carbon?A. 18.1 gB. 24.4 gC. 32.1 gD. 19.8 gE. 27.2 g

🤓 Based on our data, we think this question is relevant for Professor Dixon's class at UCF.

###### FREE Expert Solution

Use stoichiometry to determine the mass of CaC2 produced from 18.0 g C

In the balanced equation, it can be seen that 3 moles of C will produce 1 moles of CaC2

###### Problem Details

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 (C), which is mainly carbon:

CaO(s) + 3 C(s) → CaC2(s) + CO(g)

What is the amount of CaC2 (molar mass = 64.1 g mol-1) which can be produced from the reaction of excess calcium oxide and 18.0 g of carbon?

A. 18.1 g

B. 24.4 g

C. 32.1 g

D. 19.8 g

E. 27.2 g
