Calculate the molarity 14.1 moles of FeCl3 dissolved in 2350 ml of solution

Answers

Answer 1
Molarity = moles of solute/volume (in liters) of solution.

We have 14.1 moles of FeCl3, which is the solute, and the volume of our solution is 2.350 liters. So, the molarity of the solution would be (14.1 moles FeCl3)/(2.350 L solution) = 6 moles/L FeCl3 or 6 M FeCl3.

You had a closed tank of air at a pressure of 4 atm and temperature of 20 degrees Celsius. When the tank and the air are heated to 40 degrees Celsius, what is the pressure if the volume remains constant?​

Answers

Answer:

The pressure will be 4.27 atm.

Explanation:

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Where P = pressure, T = temperature, K = Constant

This law indicates that the quotient between pressure and temperature is constant.

This law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

You want to study two different states, an initial state and a final state. You have a gas that is at a pressure P1 and a temperature T1 at the beginning of the experiment. By varying the temperature to a new value T2, then the pressure will change to P2, and the following will be fulfilled:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

P1= 4 atmT1= 20 C= 293 K (being 0 C= 273 K)P2= ?T2= 40 C= 313 K

Replacing:

[tex]\frac{4 atm}{293 K} =\frac{P2}{313 K}[/tex]

Solving:

[tex]P2= 313 K* \frac{4 atm}{293 K}[/tex]

P2= 4.27 atm

The pressure will be 4.27 atm.

equilibrium?
Hzig) + 1218 = 2 Hle)

Answers

Answer: The concentration of [tex]I_2[/tex] at equilibrium is 0.45 M

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_c[/tex]  

For the given chemical reaction:

[tex]H_2(g)+I_2(g)\rightarrow 2HI(g)[/tex]

The expression for [tex]K_c[/tex] is written as:

[tex]K_c=\frac{[HI]^2}{[H_2]^1[I_2]^1}[/tex]

[tex]6.0=\frac{(0.90)^2}{(0.30)^1\times (I_2)^1}[/tex]

[tex][I_2]=0.45M[/tex]  

Thus concentration of [tex]I_2[/tex] at equilibrium is 0.45 M

Answers

Answer:

1.83 atm

Explanation:

Total pressure is the sum of partial pressures, so the pressure of hydrogen and pressure of oxygen add to equal 4.53 atm

As altitude increases, what happens to air pressure the choices are it fluctuates, it increases, it decreases or it stays the same

Answers

Answer:

it decreases

Explanation:

It is a common saying the pressure decreases with height. This means that as altitude increases, the pressure of air decreases. The higher you go above sea level, the pressure becomes lesser.

This is as a result of decrease in the amount of air above sea level and hence a decrease in the density of air as altitude increases.

Hence, with increasing altitude, pressure decreases.

Answer:

It decreases

How many grams of Si are there in a sample of Si that contains the same number of moles as a 60.8 gram sample of P?

Answers

Answer:

55.1 g Si.

Explanation:

Hello there!

In this case, for the given mole-mole relationship, it is possible to set up the following mole ratio as the moles of Si and P are the same:

1 mol Si = 1 mol P.

Next, since one mole of silicon has a mass of 28.09 g and one of phosphorous of 31.0 g, we can set up the following expression for the mass of silicon:

[tex]60.8gP*\frac{1molP}{31.0gP}*\frac{1molSi}{1molP}*\frac{28.09gSi}{1molSi}[/tex]

Therefore, the result is 55.1 grams of silicon.
