Theoretical heat of combustion of ethanol
WebbSo we write a one, and then the bond enthalpy for a carbon-oxygen single bond. And then for this ethanol molecule, we also have an oxygen-hydrogen single bond. So we'll write in here, a one, and the bond enthalpy for an oxygen-hydrogen single bond. We saw in the balanced equation that one mole of ethanol reacts with three moles of oxygen gas. WebbWhen 1g of ethanol (C 2 H 5 OH) was burned, the heat produced warmed 5 litres of water from 18 o C to 18.5 o C. What is the enthalpy of combustion of ethanol? 7. When 1g of Sulphur was burned, the heat produced warmed 110g of water from 18 0 C to 18.5 o C. What is the enthalpy of combustion of Sulphur?
