I am a chemistry student.keen in studies..I want to be at hand in chemistry.
When methanol, CH3OH, is burned in the presence of oxygen gas, O2, a large amount of heat energy is released, as shown in the combustion reaction below.
Based on the balanced thermochemical reaction above, how much heat is produced when 23.9 g of methanol react with 37.1 g of oxygen? Equation Given: CH3OH(g) + 3/2O2(g) --> CO2(g) +... more
