Answer: Hsub=Hfus+Hvap
Explanation:
The molar heat of vaporization measured in kilojoules per mole, or kJ/mol is the energy needed to make vapor one mole of a liquid. .
The molar heat of sublimation measured in kilojoules per mole, or kJ/mol is the energy needed to sublime one mole of a solid,
the molar heat of fusion measured in kilojoules per mole, or kJ/mol is the energy needed to melt one mole of a solid.
Hess law helps to explain the relationship in physical chemistry stating that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps.
In this context Hess’s law helps to see the several steps involved as the heat of sublimation energy is equal to the sum of vaporization energy and fusion energy.
Answer:
An atom cannot be subdivided into smaller particles. (Option A).
Explanation:
According to Dalton's atomic theory: All matter is composed of tiny particles called as atoms. Some postulates of this theory are given below:
1) An atom cannot be subdivided into smaller particles it means they are indivisible.
2) Different element atoms have different masses, and chemical properties.
3) All atoms which are present in an element are identical in all respects such as mass, chemical properties, etc.
4) Atom cannot create or destroyed in a closed system.
5) The types of atoms, and relative number are constant in a given compound.
Answer:
in our solar system, the rocky planets are Mercury, Venus, Earth, and Mars
hope this helps :)
Explanation:
You multiply 32 by 2, since there are two hydrogens in every water molecule.
