b. the chloride ion is twice the size of the magnesium ion.
c. magnesium and chlorine form a double covalent bond.
d. there are two chloride ions for each magnesium ion.
Answer:
The chloride ion accepted two electrons from the magnesium ion.
Explanation:
1 m
1.000 mm
= 0.025 mm
1.000 mm
O 25.000 mm; because 25 m x = 25,000 mm
1 m
25.000 mm; because 25 m X
100 mm
= 2500 mm
1 m
O 0.025 mm; because 25 m x
1 m
100 mm
= 0.25 mm
Answer:
25000 mm: because 25 m × 1000 mm /1 m = 25000 mm
Explanation:
We can convert 25 m to millimetre (mm) by doing the following:
Recall:
1 m = 1000 mm
Therefore,
25 m = 25 m × 1000 mm /1 m = 25000 mm
25 m = 25000 mm
Thus, 25 m is equivalent to 25000 mm
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 Ksp Expression for the given solid in molar solubility terms is; Ksp = 4x³
Ksp is simply defined as solubility product constant and it is the equilibrium expression for the dissolving of a solid.
Now, the solid ab₂ dissolved as shown in the formula;
ab₂(s) → a(aq) + 2b(aq)
Thus, the equilibrium constant is;
Ksp = ([a][b]²)/[ab₂]
Now, since the solids are not put into the equation as a result of not having enough concentration, it can be simplified to;
Ksp = [a][b]².
Now, Molar solubility another term for molarity and as such it means we will say; x = a
Since b = 2x, there is twice the amount of b than a and as such we can write a and b in terms of x to get;
Ksp = [x][2x]² = 4x³
