How many moles of gas are required to exert 15.4 atm of pressure in a 2.92 L container at 32.0°C

Chemistry

Iteru [2.4K]3 years ago

Answer:

1.8 moles

Explanation:

Number of moles = ?

Pressure = 15.4 atm

Volume = 2.92L

Temperature = 32°C = (32 + 273.15)K = 305.15K

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume in which the gas occupies

n = number of moles

R = ideal gas constant = 0.082J/mol.K

T = temperature of the gas

PV = nRT

n = PV / RT

n = (15.4 * 2.92) / (0.082 * 305.15)

n = (44.968 / 25.0223)

n = 1.797 moles = 1.8 moles

Number of moles of the gas is 1.8 moles

What is the tyndall effect
zzz [600]

Answer: Tyndall effect is the scattering of light due dispersed colloidal particles that does not settle in a solution. Colloidal particles constantly moves because of Brownian motion and blocks or hinders light particles to pass through. Colloidal particles are medium sized particles but smaller enough than suspension.

Do you expect potassium iodide to be soluble in cyclohexane
Allushta [10]
Answer is: no, <span>potassium iodide has low solubility in cyclohexane.
</span>Potassium iodide (KI) is ionic compound, salt, that dissolve good in polar solvents (for example water), but it is very low soluble in non-polar solvents (in this example cyclohexane C₆H₁₂).
<span>Cyclohexane has zero net polarity, because it is a symmetric molecule, with sp2 hybridization of carbon.</span>

According to the rock cycle, which of the following transitions are possible? Assume an unlimited number of steps.
Vikentia [17]

(D)All of the above are possible.

Explanation:

According to the rock cycle, all of the transitions given are possible with several unlimited steps.

The rock cycle shows how the different rock types are transformed from one form to another.

In the rock cycle the major rock types are taken into consideration. These rock types are Igneous, sedimentary and metamorphic.

  • An intrusive igneous rock becomes a sedimentary rock.

Based on the rock cycle, an intrusive rock can become a sedimentary rock. This is igneous to sedimentary rock conversion. Here, the intrusive rock is brought during a terrain change to the surface. Weathering, erosion, transportation and deposition combines to produce sediments and take them to their basin of deposition where they form sedimentary rocks.

  • A sedimentary rock becomes soil.

By weathering, a sedimentary rock can be come a soil. Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soil.

  • A metamorphic rock becomes an extrusive igneous rock.

When metamorphic rocks are subjected to intense heat and pressure, they reach their melting point.

As they melt, they produce magma which can be brought to the surface to form extrusive volcanic rocks.

What is the relationship between particle collisions and reaction rates?
4vir4ik [10]

Answer:

Collision theory states that the rate of a chemical reaction is proportional to the number of collisions between reactant molecules. The more often reactant molecules collide, the more often they react with one another, and the faster the reaction rate.
