This problem is providing us with the mass of propane, its enthalpy of combustion, and the initial and final temperature of water that can be heated from the burning of this fuel. At the end, the result turns out to be 42.27 L.
<h3>Combustion:</h3>In chemistry, combustion reactions are based on the burning of fuels by using oxygen and producing both carbon dioxide and water. For propane, we will have:
Hence, we can calculate the heat released from this reaction by using the mass, which has to be converted to moles, and the given enthalpy of combustion:
In chemistry, we can analyze the mass-specific heat-temperature-heat relationship via the most general heat equation:
Thus, since Q was obtained from the previous problem, but the sign change because the released heat is now absorbed by the water, one can calculate the mass of water that rises from 20.0°C to 100.0°C with this heat:
Finally, we convert it to liters as required:

Answer:
Explanation:
The question is based on the concept of the cleavage of bonds. In the process of the reaction the breaking of bonds is required. The cleavage of the bonds make the bonded electrons free to involve in the reaction process.
Fundamentals:
The cleavage of the bond can be done in two ways: homolytic or heterolytic. The heterolytic cleavage occurs when the shared electrons of the covalent bond are taken away by either of the atom. The heterolytic cleavage results in generation of the charged molecules. On the other hand, the homolytic cleavage is the cleavage in which the shared pair of the electrons are equally distributed, resulting in generation of free radicals.
