Answer: 35.1 kJ/mol
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
(1)
(1)
The final reaction is:
(3)
By adding (1) and (2)
Hence the expected value for the heat of sublimation of acetic acid is 35.1 kJ/mol
Answer: Some atoms of the same elements that have different atomic masses are called isotopes
Explanation:
so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.

Answer:
Sulfur is characterized as a non-metal because it is consistent with the 3 physical properties listed for nonmetals. It is a poor conductor of heat and electricity because the electrons are not free to move. ... Sulfur has a low density because it has less volume for its electron cloud.
