Select the correct layer.<br> In which layer is lithification most likely to occur?
Vera_Pavlovna [14]

Answer:

"Subsoil" is the correct answer.

Explanation:

  • The method of transforming sediments become rocky solids is considered as Lithification. The floor stratum or level below the upper floors at the base of the floor is a Subsoil.
  • Sediments comprise materials particles like sand, pebbles, skeletons kind of bones as well as muck, that were transported and produced instead in water or perhaps wind someplace.

A sample of gas occupies a volume of 4.5 L at 20 Celsius. What volume will it occupy at -15 celsius, if the pressure remains con
nataly862011 [7]

Answer: 3.96L

Explanation:

PV = nRT

The way I like to do it, it's I get rid of whatever I do not need.

We have to do an equation for sure to make both sides equal and find our desired result.

The pressure is constant, so it would be constant in both sides, therefore, there is no point in using it.

The R is a constant used in both sides so there is no point on using it either.

We don't need to work with moles in this case, so let's forget about the moles.

Therefore we are left with only V (volume ) and T(Temperature)

Which would logically make this:

V1/T1 = V2/T2

OR

T1/V1 = T2/V2

Both of these would work, we always use whatever makes our calculations easier without complicating our lives with the algebra.

That should remind you of Charles' Law

Transform degrees into kelvins

20 + 273.15 = 293.15K

-15 + 273.15 = 258.15K

So, 4.5L/293.15K = V2/258.15K

V2 = (4.5L/293.15K) x 258.15K

V2 = 3.96L

Which compound in each pair is more soluble in water?(b) Calcium phosphate or magnesium phosphate
Sidana [21]

<u>larger is the value of </u>Ksp<u> the higher will the solubility of solid in water.</u>

What is called compound?

  • In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
  • When the elements come together, they react with each other and form chemical bonds that are difficult to break.
  • These bonds form as a result of sharing or exchanging electrons between atoms.

The equation for the dissociation of a solid MX in water is given below

MX(s) ⇄ Mⁿ⁺(aq) + Xⁿ⁻ (aq)

Assume s be the solubility of MX in pure water, then the equilibrium concentrations of ions are

[ Mⁿ⁺] = s

[ Xⁿ⁻ ] = s

The expression for the solubility product constant (Ksp) is as follows

Ksp = [ Mⁿ⁺] [ Xⁿ⁻ ]

       = s²

That is, larger is the value of Ksp the higher will the solubility of solid in water.
