Assume 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/ mol)
Answer to relevant QuestionsSyngas can be burned directly or converted to methanol. Calculate ΔHo for the reaction CO(g) + 2H2(g) → CH3OH(l) Determine ΔE for the process H2O(l) → H2O(g) at 25oC and 1 atm. The enthalpy of neutralization for the reaction of a strong acid with a strong base is 256 kJ/ mol of water produced. How much energy will be released when 200.0 mL of 0.400 M HNO3 is mixed with 150.0 mL of 0.500 M KOH? The heat required to raise the temperature from 300.0 K to 400.0 K for 1 mole of a gas at constant volume is 2079 J. The internal energy required to heat the same gas at constant pressure from 550.0 K to 600.0 K is 1305 J. ...You have a 1.00-mole sample of water at 230oC, and you heat it until you have gaseous water at 140.oC. Calculate q for the entire process. Use the following data: Specific heat capacity of ice = 2.03 JoC-1g-1 Specific heat ...
