What is Enthalpy?
Enthalpy term is basically used in thermodynamics to show the overall energy that a matter have. Mathematically, Enthalpy is directly proportional to specific heat capacity of a substances. Specific heat capacity of a substance is the amount of heat required to raise the temperature by one degree Celsius of one gram of a substance.

Answer:
To answer, all living organisms contain carbon-based compounds, which classifies them organic.
Simply, carbon dioxide, is an example of an inorganic compound since it does not contain both carbon and hydrogen. Alternatively, one molecule of carbon dioxide contains one atom of carbon and two atoms of oxygen.

The vapor pressure of a compound refers to the pressure generated by the vapour of a compound in equilibrium with its condensed stage. The major determinant of a compound vapour pressure is temperature. The vapour pressure of an aqueous solution of sodium chloride will be lower than that of pure water. This is because, dissolution of solute in a solvent always reduces the vapour pressure of the solution as a result of interactions between the molecule of the solute and the solvent. Thus, a pure compound will always have a higher vapour pressure than a solution.

Answer: Electrons
Explanation: In chemical reactions, elements and compounds change in order to form different substances. This changes can be:
1. oxidation state: which is define as the charge of the atom
2. bonding: atoms in a compound are bonded, this bonds can break so atoms rearrange to form different substances
In this changes electrons are involve. The charge depends on the amount of negative charge of electron respect to positive charge of proton in nucleus which remain the same, otherwise we would be talking about nuclear reactions.
Also, bonding depends on the electrons that atoms can give, receive or share to form ionic or covalent bonds.
