The enthalpy of combustion of propane is -2202.0 kJ/mol.
The enthalpy of combustion is released when one mole of compound is burned in the presence of excess oxygen. The bonds between carbon and hydrogen in the compound are broken and bonds between carbon and oxygen are formed as well as bonds between hydrogen and oxygen are formed.
The model correctly describes the locations of protons and electrons in the wave mechanical model of the atom is the <span>proton in nucleas, electron in regions of most probable location.

Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Explanation:
In gases and liquids, heat is usually transferred by convection, in which the motion of the gas or liquid itself carries heat from one place to another. ... If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.
