Use the reaction 2ClF3(g) + 2NH3(g) → N2(g) + 6HF(g) + Cl2(g) ΔHo = –1196 kJ to calculate ΔHof for ClF3(g).
Answer to relevant QuestionsCalculate the internal energy change for each of the following. a. One hundred (100.) joules of work are required to compress a gas. At the same time, the gas releases 23 J of heat. b. A piston is compressed from a volume of ...Ethanol (C2H5OH) has been proposed as an alternative fuel. Calculate the standard enthalpy of combustion per gram of liquid ethanol. A piece of chocolate cake contains about 400 Calories. A nutritional Calorie is equal to 1000 calories (thermo-chemical calories). How many 8-in-high steps must a 180-lb man climb to expend the 400 Cal from the piece of ...Using the following data, calculate the standard heat of formation of ICl(g) in kJ/ mol: Cl2(g) → 2Cl(g) ΔHo = 242.3 kJ I2(g) → 2I(g) ΔHo = 151.0 kJ ICl(g) → I(g) + Cl(g) ΔHo = 211.3 kJ I2(s) → I2(g) ΔH8 = 62.8 ...The best solar panels currently available are about 15% efficient in converting sunlight to electricity. A typical home will use about 40 kWh of electricity per day (1 kWh = 1 kilowatt hour; 1 kW = 1000 J/ s). Assuming 8.0 ...
