Since the helium gas has a volume of 1.00 L, the final volume of the helium gas is 1.00 L

To find the volume, we need to know the general gas law.

The general gas law is given by P₁V₁/T₁ = P₂V₂/T₂ where

So, making V₂ subject of the formula, we have

V₂ = P₁V₁T₂/T₁P₂

Since the sample of helium gas has a volume of 1.00 L and both the pressure and kelvin temperature each double, we need to find its final volume.

So,

So, substituting the values of the variables into the equation, we have

V₂ = P₁V₁T₂/T₁P₂

V₂ = P₁V₁ × 2T₁/T₁ × 2P₁

V₂ = V₁

V₂ = 1.00 L

So, the final volume of the helium gas is 1.00 L

It is evident from the provided map that the African Ocean is enlarging at a divergent plate boundary. So, the correct option is B.

When two tectonic plates diverge from one another, the area is known as a diverging plate border. New crust forms on the plate margins when the plates divide and magma rises from the mantle to fill the space. The creation of mid-ocean ridges is a result of this process, known as seafloor spreading.

Divergent plate borders can also occur on land, and they can eventually result in the formation of new ocean basins by forming rift valleys. The spreading of the seabed is aided by the divergent limits in the middle of the ocean. A fracture occurs on the ocean floor as plates made of oceanic crust move apart from one another.  

Therefore, the correct option is B.

V(real) will be:

= V(ideal)/12

= 1.368/12 = 0.114

The compression factor will be:

= 1.368/(12 × 1.368)

0.227L is the volume of a 3.95 M potassium chloride solution that would be needed to make 325 mL of a 2.76 M solution by dilution.

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Moles of KCl in new solution

There are two subshells that are s and p, which are present in the second energy level.

The energy level can be defined as the fixed distances from the nucleus of an atom where electrons may be found. Each energy level is divided into some Subshells. These subshells are known as s-subshell, p-subshell, d-subshell, and f-subshell. This subshell contains some orbitals, these orbitals are the place where there is the maximum probability of getting the electrons. In one orbital, a maximum of two electrons can be present.

Answer:

the temperature of the system decreases

Ionic compounds such as sodium chloride, which dissolve in water and dissociate to form ions, are called electrolytes.

Electrolytes are substances that have a natural positive or negative electrical charge when dissolved in water.

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

It is a tension created by the attraction of molecules to the surface by the molecules in a bulk of a solution.

The attraction force present between water molecules is cohesion force.

The phenomenon of surface tension provides two major characteristics to the water:

Plants take water from soil using it's roots , and water is travelling through the xylene tissues present in a plant , so the cohesion forces present in water helps it to travel to the higher places in plants.

While in case of animals, this attraction forces increases the surface density which helps to insects to walk on to the water surface.

Approximately 11460 Years Old

Explanation:

i looked this up :/

way to much maths for me

The age of the bone given that it contains C-14 and N-14 in ratio of 1:3 is 11460 years

C-14 is usually used for radioactive dating (i.e to determine the aga of substance)

From the question, C-14 and N-14 exist in ratio of 1:3.

thus, the amount of C-14 remaining can be obtained as follow:

Percentage of C-14 remaining = 1/4 × 100

Percentage of C-14 remaining = 25%

2ⁿ = N₀ / N

2ⁿ = 100 / 25

Explanation:

Decomposition reactions involve a substance breaking down into simpler substances.

9-fluorenone is a limiting reagent and theoretical yield.

Fluoren-9-ol is a member of the class of hydroxyfluorenes that is 9H-fluorene substituted by a hydroxy group at position 9.

Inspect stoichiometry of the given reaction as per the balanced equation below:

[tex]4C_{13}H_8O + NaBH_4 + 4CH_3 OH[/tex] → [tex]4C _{13} H _{10} O + NaB(OCH_3 )_4[/tex]

Given weight:

0.6 grams methanol

0.05 grams 9-fluorenol

0.792 [tex]NaBH_4[/tex]

Out of the three reactants, [tex]NaBH_4[/tex] acts as a reducing agent only and hence the reaction can occur only when [tex]NaBH_4[/tex] is present in relatively much smaller amounts. But the yield of the product,9-fluorenol, is not governed by its quantity.

Theoretically, when equimolar amounts of reactants ( 9-fluorenone and methanol ) are taken for reaction in presence of [tex]NaBH_4[/tex] an equivalent quantity of product, 9- fluorine is obtained, as inspected in the above stoichiometric relations. But practically we have used a lesser number of moles of 9-fluorenone than theoretically needed, hence in this case it should serve as the limiting reagent.

9- fluorenone, methanol & [tex]NaBH_4[/tex] are the reactants, while the product 9-fluorenol would be obtained = 0.0033 moles

This would represent the theoretical yield of the product 9-fluorenone, as we have used an excess of methanol thus facilitating the reaction to go to completion.

Hence, 9-fluorenone is a limiting reagent.
