According to the soil texture triangle, if you have 25% silt, 25% clay, and 50% sand, which soil texture class do you have?.

Answers

Answer 1

According to the soil texture triangle, if we have 25% silt, 25% clay, and 50% sand, then the soil is Sandy clay loam.

According to soil texture triangle 25% silt, 25% clay and 50% sand having the sandy clay loam structure. This type of soil has the sand as a major content but it also have clay and silt with definite proportion. This soil is used for the purpose of guarding. But this soil cannot hold more amount of water as well as nutrients which requires for the growth of plant.

Hence, the type of the soil is sandy clay loam soil.

Answers

The initial pressure in the 50.0L bulb is 2.75 atm.

What is Boyle's Law?

According to Boyle's law in a constant temperature, the volume of a gas is inversely proportional to its pressure.  

V ∝ 1/P  

PV = constant.

It is given to us, Initial volume(V) = 250L and Final volume(V') = 50.0 L

Say final pressure is P', that implies initial pressure P = P'- 2.20

Now, according to the concept of Boyle's law, PV = P'V'

⇒P' = PV/V'

⇒P' = (P'-2.20)*250 / 50

⇒P' = 2.75 atm

Answers

Answer:

if an element has atomic number of 15 then the atom has 15 electrons also.

Option (b)

Explanation:

remember the atomic number of an element is also the number of protons of that element, we know that protons have a positive charge, neutrons have no charge and electrons have a negative charge.

we also know that an element is atomically neutral, meaning it overall has no charge, this is because the positive proton attracts a negative electron and hence their charges cancel off.

this is why in all elements, the atomic number(proton number) will always be equal to the electron number.

Note the neutron number cannot be predicted this way, as far as I know, the neutron purpose is mainly to add Mass to the atom so that it can be more stable, though often times the neutron number is similar to the proton number also.

What is its molecular formula given that its molar mass is about 162 g?.

Answers

The molecular formula of the Allicin is, C₁₈H₃₀S₆O₃ and the empirical formula is C₆H₁₀S₂O

the molecular formula can be calculated as follows:

If a percentage is provided, we will assume that the entire mass is 100 grams.

As a result, each element's mass is equal to the percentage indicated.

C weighs 44.4 g.

H weighs 6.21 g.

S weighs 39.5 g.

O's mass is 9.86 g.

C has a molar mass of 12 g/mole.

H has a molar mass of 1 g/mole.

S has a molar mass of 32 g/mole.

O has a molar mass of 16 g/mole.

first, convert given masses into moles.

Moles of C =      mass C       =    44.4 g      = 3.7 moles

                    molar mass C       12 g/mole.

Moles of H =      mass H       =    6.21 g.      = 6.21 moles

                      molar mass           1 g/mole.

Moles of S =      mass S       =    39.5 g.      = 1.23 moles

                      molar mass          32 g/mole.

Moles of O =        mass O       =    9.86 g.      = 0.62 moles

                      molar mass          16 g/mole.

then we find the mole ratio by divide each value of moles by the smallest number of moles calculated.

For C = 3.7 moles = 5.96 ≈ 6

           0.62 moles

For H = 6.21  moles = 10.01≈ 10

           0.62 moles

For S = 1.23 moles = 1.98 ≈ 2

           0.62 moles

For O = 0.62 moles = 1

             0.62 moles

The ratio of C : H : S : O = 6 : 10 : 2 : 1

The Empirical formula is C₆H₁₀S₂O

The empirical formula weight = 6(12) + 10(1) + 2(32) + 1(16) = 162 gram/eq

Now we have to calculate the molecular formula of the compound.

C (diamond)  + O₂   ----->  CO₂

At room temperature the value of S°  is given as follows :

carbon, C = 2.38 J / Kmol

oxygen, O₂ = 205.2 J/Kmol

carbon dioxide, CO₂ = 213.8 J/Kmol

The standard entropy change is given as :

ΔS° = ∑S° product  - ∑ S° reactant

ΔS° = ( 213.8 ) - ( 2.38 + 205.2)

ΔS° = 213.8 - 207.58

ΔS° = 6.22  J / K mol

The standard entropy change for the combustion of 1 mole of diamond at room temperature is 6.22  J / K mol.
