Solution: Calcium carbide (CaC2) reacts with water to produce acetylene (C 2H2) according to the equationCaC2(s)  +  H2O(l) → Ca(OH)(s)  + C2H2(g)A certain mass of CaC2 reacts completely with water to give 64.5

Problem

Calcium carbide (CaC2) reacts with water to produce acetylene (C 2H2) according to the equation

CaC2(s)  +  H2O(l) → Ca(OH)(s)  + C2H2(g)

A certain mass of CaC2 reacts completely with water to give 64.5 L of C 2H2 at 50.0°C and P = 1.00 atm. If the same mass of CaC2 reacts completely at 400.0°C and P= 2.00 atm, what volume of C2H2 (in L) can be collected at the higher temperature and pressure?

a) none of the given answers

b) 516

c) 0.015

d) 67.2

e) 258
