Answer: In both ionic and molecular bonds, the resulting compound is stabilized because each atom's outer electronic orbital is full.
Explanation:
Molecular bonds are also called covalent bonds. A covalent bond is formed by sharing of electrons between two or more atoms.
For example, atomic number of hydrogen is 1 and atomic number of nitrogen is 7 (2, 5). In order to attain stability hydrogen atom needs to gain one electron whereas nitrogen needs to gain 3 electrons.
Hence, 3 atoms of hydrogen chemically combine with one atom of nitrogen by sharing electrons and thus it forms the compound .
Ionic bonds are the bonds formed by transfer of electrons from one atom to another.
For example, atomic number of sodium is 11 (2, 8, 1) and atomic number of chlorine is 17 (2, 8, 7). In order to attain stability sodium needs to lose one electron whereas chlorine needs to gain one electron.
Hence, when sodium combines chemically with chloride then sodium will transfer its 1 valence electron to the chlorine atom and thus it forms the compound NaCl.
Therefore, we can conclude that in both ionic and molecular bonds, the resulting compound is stabilized because each atom's outer electronic orbital is full.
Explanation:
The given data is as follows.
q = -25.0 kJ, Pressure (P) = 1.50 atm
= (12 - 6) L = 6 L
Therefore, product of pressure and change in volume will be as follows.
= 7.5 L atm
=
= 759.75 J
Now, we will calculate the change in internal energy as follows.
=
= -25000 kJ + 759.75 J
= 24240.25 J
or, = 24.240 kJ (as 1 kJ = 1000 J)
Thus, we can conclude that the change in internal energy () for a system is 24.240 kJ.
