Methanol, CH3OH, is an efficient fuel with a high octane rating that can be produced from coal and hydrogen.
CH3OH(g) + 3 2 O2(g) β CO2(g) + 2H2O(l) βH = -764 kJ
a. Find the heat evolved when 90.0 g of CH3OH(g) burns in excess oxygen.
b. What mass of O2 is consumed when 945 kJ of heat is given out?
11. Calculate the amount of energy liberated when 3.5 mol of pentane are combusted. C5H12(l) + 8O2(g) β 5CO2(g) + 6H2O(l) βH = -23.11 kJ/g
