heat realeased from the reaction of CaC2 with water
Not what you're looking for?
Calcium carbide (CaC2) reacts with water to form acetylene (C2H2), a gas used as a fuel in welding:
CaC2 + 2H2O ==> C2H2 + Ca(OH)2 ^H = 128.0 kJ
How many kilograms of CaC2 are consumed in a raction that releases 3.64 x 104 kJ of heat under these conditions?
A. 1.82 x 10 to the power of 4 kg
B. 284 jg
C. -18.2 kg
D. 2.33 x 10^3 kg
E. 18.2 kg
