Chemistry

Harrizon [31]3 years ago

Answer:

The correct answer to this is Mg.

Explanation:

Mg is the second element at the Periodic Table, down Be. As its the oxidation number is 2, it can release two electrons to form compounds. Not like C that is tetravalent, or Na that is a monovalent element (1e-). Si, as C has 4 oxidation states, and phosphorus can lose or get 3 e- (for example PCl3), also get 5e- (for example  P2O5)

How does bonding and antibonding molecular orbitals interaction stabilize Molecules?
elena-s [515]

Answer:

Both decrease the energy of the atomic orbitals to form the molecule by their overlap

Explanation:

Many molecules are not described correctly by Lewis theory. For example, diborane (B2H6), which is an electrodeficient compound: there are not enough valence electrons to be able to assign a Lewis structure.

The theory of binding and anti-binding orbitals describes molecular orbitals, whose atomic orbitals overlap to form them. Two atomic orbitals overlap giving a binding orbital molecular orbital. In the binder, the electrons that occupy it have a high possibility of being located between the atoms, so filling stabilizes the molecule. In an anti-binding orbital, the electrons that occupy it have a low probability of being located between the atoms, so that their filling destabilizes the molecule.

The interaction between two atomic orbitals is greater the greater their overlap and the smaller their energy difference.

If molten sodium chloride is split by electrolysis, which reaction occurs at the anode?
mariarad [96]

Answer: 2Cl^-(l)\rightarrow 2e^-+Cl_2(g)

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.  

In the electrolysis of molten sodium chloride, sodium metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

2NaCl(l)\rightarrow 2Na^++2Cl^-

At anode : 2Cl^-(l)\rightarrow 2e^-+Cl_2(g)

At cathode : 2Na^+(l)+2e^-\rightarrow 2Na(l)
