Answer:
C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O
Explanation:
Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.
As a result, this is the sole reaction that obeys the general combustion equation.
Answer:
Desertification
Explanation:
Desertification is the process by which land becomes more desertlike and unable to support life. This happens when to many livestock overgraze an area.
Explanation:
Noble gas configuration is defined as the configuration which contains completely filled orbitals.
For example, oxygen atom when gain two electrons then it forms oxygen ion (
).
Atomic number of oxygen atom is 8 and so, its number of electrons will also be 8. But when it gain two electrons then it has total 10 electrons. Hence, electronic configuration of
is as follows.

Since, there are completely filled orbitals in an
ions. Therefore, it means this ion has a noble-gas configuration.
Thus, we can conclude that any specie which shows completely filled orbitals will have noble-gas configuration.
