The Bunsen burner in your labs are fueled by natural gas, which is mostly methane, CH4. The
thermochemical equations for the combustion of methane (burning in oxygen) is:
CH4(g) + 2 O2(g) ➔ CO2(g) + 2 H2O (g) ΔH = – 890.3 kJ/mole
Calculate ΔH in kJ when 5.00 g CH4 react with an excess oxygen.
Q3: B:
A 208 g of C6H6 (78 g/mol.) burns in air according to the equation:
CHs + O2 - CO2 +H2O
What mass of CO2 (44 g/mol.) is produced?
The enthalpy of combustion of benzoic acid (C6 H5 COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be −3226.7 kJ/mol. When 1.9862 g of benzoic acid are burned in a calorimeter, the temperature rises from 21.84°C to 25.67°C. What is the heat capacity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2000 g.)
