Enthalpy of combustion glycerol

WebBond enthalpy is the energy that it takes to break one mole of a bond. So one mole of a bond. So different types of bonds will have different bond enthalpies. So as an example, we can talk about a carbon hydrogen bond, or a carbon hydrogen single bond. So this carbon is probably attached to some other stuff, because carbons usually have more ... WebThe specific heat capacity of water is 4.18 J/(g · °C), meaning it takes 4.18 J to raise the temperature of 1 g of water by 1°C. Calculate the heat of combustion in kJ/g for the sample of biodiesel you burned. The heat of combustion is the quantity of thermal energy given off when a certain amount of a substance burns.
