Answer:
Metallic bonding
Explanation:
Metals have low ionization energies. Therefore, their valence electrons are easily delocalized (attracted to the neighbouring metal atoms). These delocalized electrons are then not associated with a specific metal atom. Since the electrons are “free”, the metal atoms have become cations, and the electrons are free to move throughout the whole crystalline structure.
We say that a metal consists of an array of cations immersed in a sea of electrons
.
The electrons act as a “glue” holding the cations together.
Metallic bonds are the attractive forces between the metal cations and the sea of electrons.
In an NaK alloy, for example, the Na and K atoms contribute their valence electrons to the "sea". The atoms aren’t bonded to each other, but they are held in place by the metallic bonding.
A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Answer:


Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Thus, Kp for this reaction is computed based on the given molar fractions and the total pressure at equilibrium, as shown below:


Now, by using the Van't Hoff equation one computes the equilibrium constant at 298.15K assuming the enthalpy of reaction remains constant:

Finally, the Gibbs free energy for the reaction at 298.15K is:
