the moon passes through the earth's shadow ??
H2 is known to exist. For dihydrogen, H2, we can identify the frontier molecular orbitals (FMOs). The highest occupied molecular orbital (or HOMO) is the σ (sigma) 1s MO. The lowest unoccupied MO (LUMO) is the σ* (sigma star) 1s MO which is antibonding.

Vapourization is the conversion of the water into a gaseous state. The energy flow of vaporization is similar to that of the melting.
<h3>What are melting and vaporization?</h3>
Vapourization is the physical change that converts the liquid state of matter into a gaseous state. Whereas melting is the process that involves the conversion of the solid ice into the liquid water.
Both the process of vaporization and melting absorbs heat from their surrounding system to convert the state of matter, while the process of freezing release heat to convert the liquid into solid.
Therefore, the flow of energy of vaporization is similar to melting.

Answer:
A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. A reaction that occurs in two or more elementary steps is called a multistep or complex reaction. ... The slowest step in a reaction mechanism is known as the rate-determining step.
