Which of these statements best explains why the soil around a volcanic region is fertile? Select one:
a. Volcanoes always contribute to flooding, which enriches the soil.
b. Volcanoes aid in the formation of new rocks, which help form fertile soil.
c. Particles released in the air by volcanoes fall to the ground and enrich the soil.

Answer:
The correct statement is option c, that is, particles discharged in the air by volcanoes fall to the ground and enrich the soil.
Explanation:
The eruptions of volcanoes lead to the dispersion of ash over the broader regions surrounding the site of eruption. On the basis of the chemistry of the magma, the ash will be comprising different concentrations of soil nutrients. While the major elements found in the magma are oxygen and silica, the eruptions also lead to the discharging of carbon dioxide, water, hydrogen sulfide, sulfur dioxide, and hydrogen chloride.
In supplementation, the eruptions also discharge bits of rocks like pyroxene, potolivine, amphibole, feldspar that are in turn enriched with magnesium, iron, and potassium. As an outcome, the areas which comprise huge deposits of the volcanic soil are quite fertile.
Answer:
Option (C)
Explanation:
The volcanic eruptions are usually very destructive but it also has some advantages of which, one is that it makes the soil fertile in the nearby region.
During the time of the volcanic eruption, a large number of pyroclastic materials, blocks and ashes that are comprised of various gases are released, which eventually adds to the soil of the nearby areas. These materials ejected from the volcano are rich in various minerals such as oxygen, silicon, and some amount of CO₂, SO₂, and HCl which facilitates the growth of the soil and increases its productivity.
Thus, the soil around a volcanic region is much fertile.
Hence, the correct answer is option (C).

The correct answer is option A) Oxidation
Final answer:
The release of energy through the removal of hydrogen from a molecule is referred to as oxidation. In this process, energy is often released which can be utilized by cells for different functions.
Explanation:
The release of energy from a molecule by the removal of hydrogen is known as A) Oxidation. In biochemical reactions, oxidation refers to the process in which electrons are removed from a molecule, usually by removing a hydrogen atom (which consists of one proton and one electron). This process often releases energy that can be used by cells for various functions. Thus, through oxidation, molecules such as carbohydrates or fats can be broken down to release energy used for cellular activities.

Answer:
17 atoms are in 3(SO)4
Explanation:
Final answer:
There are 15 total atoms in
Explanation:
To find the total number of atoms in a chemical formula like 3(SO)4, you need to multiply the subscripts (the numbers outside the parentheses) by the number of atoms represented by each element within the parentheses and then multiply that by the coefficient (the number outside the formula).
In this case, you have:
Now, let's break it down:
The subscript for sulfur (S) is 1.
The subscript for oxygen (O) is 4.
So, for each (SO4) unit, you have 1 sulfur atom and 4 oxygen atoms.
Now, multiply this by the coefficient of 3:
= 3 * (1 sulfur atom + 4 oxygen atoms)
= 3 sulfur atoms + 12 oxygen atoms
So, in , there are a total of 3 sulfur atoms and 12 oxygen atoms, for a combined total of 15 atoms.

Answer: It has polar bonds and a symmetrical structure.
Explanation:
Formula used for calculating hybridization
where, V = number of valence electrons present in central atom i.e. boron= 3
N = number of monovalent atoms bonded to central atom=3
C = charge of cation = 0
A = charge of anion = 0
The number of electrons is 3 that means the hybridization will be and the electronic geometry of the molecule will be trigonal planar.
Thus as there are no lone pair of electrons, there is no distortion and the molecule is symmetrical. The B-F bonds are polar due to electronegativity difference but the polarities cancel due to symmetrical structure.
