The complete combustion of acetylene [C2H2(g)] produces 1300. kJ of energy per mole of acetylene consumed. How many grams of acetylene must be burned to produce enough heat to raise the temperature of 1.00 gal of water by 10.0oC if the process is 80.0% efficient? Assume the Density of water is 1.00 g/ cm3.
Answer to relevant QuestionsAssume that 4.19 × 106 kJ of energy is needed to heat a home. If this energy is derived from the combustion of methane (CH4), what volume of methane, measured at STP, must be burned? (ΔHoCombustion for CH4 = –891 kJ/ ...Consider the following cyclic process carried out in two steps on a gas: Step 1: 45 J of heat is added to the gas, and 10. J of expansion work is performed. Step 2: 60. J of heat is removed from the gas as the gas is ...If a student performs an endothermic reaction in a calorimeter, how does the calculated value of ΔH differ from the actual value if the heat exchanged with the calorimeter is not taken into account? Write reactions that correspond to the following enthalpy changes: a. ΔHof for solid aluminum oxide b. the standard enthalpy of combustion of liquid ethanol [C2H5OH(l)] One mole of H2O(g) at 1.00 atm and 100oC occupies a volume of 30.6 L. When 1 mole of H2O(g) is condensed to 1 mole of H2O(l) at 1.00 atm and 100oC, 40.66 kJ of heat is released. If the Density of H2O(l) at this temperature ...
