That makes sense. Thanks for the help.Borek said:By definition I would say. II doesn't burn, it stays unchanged.
The enthalpy of combustion is the amount of heat released when a substance undergoes complete combustion in the presence of oxygen. It is a measure of the energy stored in chemical bonds within the substance.
Oxygen is a highly stable molecule and does not undergo combustion itself. Therefore, when it is used as a reference point for measuring enthalpy of combustion, it is assigned a value of 0Kjmol-1.
The enthalpy of combustion is calculated by measuring the change in temperature of a system during combustion and using the formula Q = mcΔT, where Q is the heat released, m is the mass of the substance, and ΔT is the change in temperature.
The enthalpy of combustion can be affected by the type of substance being combusted, the amount of oxygen present, and the temperature and pressure of the system. It can also be affected by any impurities in the substance being combusted.
The enthalpy of combustion is important in understanding the energy content of different substances and their potential as fuels. It is also used in various industrial processes, such as power generation and chemical production, to determine the efficiency of combustion reactions.
