Answer:
A compound can easily be split up into its different elements.
Explanation:
The modern definition of electronegativity is due to Linus Pauling. It is the power of an atom in a molecule to attract electrons to itself.
When the electronegativity difference between the two atoms is greater than 2.0, the bond is considered ionic; i.e. there is complete transfer (between the two atoms) of the electrons in the bond. The electronegativity (according to Pauling scale) of chlorine is 3.0, while the electronegativity of sodium is 0.9.
So, electrons are transferred because of a larger electronegativity difference.
Element name: Neon
element symbol: Ne
atomic number: 10
atomic mass: 20.1797
number of protons: 10
number of neutrons: 10
number of electrons: 2,8
interesting fact: the name means new, and it is pulled out of the air.
for the rest just add a neon bohr model ig
Answer:
ΔS surrounding (entropy change of the reservoir) = -1 J/K
Explanation:
Given:
Change in heat (ΔH) = 150 joules
Temperature (T) = 150 K
Find:
ΔS surrounding (entropy change of the reservoir)
Computation:
ΔS surrounding (entropy change of the reservoir) = - ΔH / T
ΔS surrounding (entropy change of the reservoir) = - 150 / 150
ΔS surrounding (entropy change of the reservoir) = -1 J/K
