Question

A 1.00-g sample of the ethane, C2H6(g) is burned (in an atmosphere of excess oxygen) in a bomb calorimeter (?V = 0) containing 1200. g of water; this being a large enough number of moles of water, so that you may neglect the heat capacity of C2H6(g) and O2(g) and any reaction products. The temperature of the water and the bomb calorimeter rises from 24.62

Explanation / Answer

A) C2H6 + 7/2 O2 ---> 2CO2 + 3 H2O B)given that temperature raised from 24.62 to 28.16 so heat produced is (Mc+Mw*1200)(28.16-24.62) Mc and Mw heat capacity of calorimeter and water Mc = 837 Mw = 4.2 j / gram so = 20.8 Kj/gram of C2 H6
