Consider the reaction below. Upper C upper C l subscript 5 (g) double-headed arrow upper P upper C l subscript 3 (g) plus upper C l subscript 2 (g). At 500 K, the reaction is at equilibrium with the following concentrations. [PCI5]= 0. 0095 M [PCI3] = 0. 020 [CI2] = 0. 020 M What is the equilibrium constant for the given reaction? 0. 042 0. 42 2. 4 24.

Answers

The equilibrium constant of the reaction is 0.042.

The reaction equation is given as;

PCl5(g) ⇄ PCl3(g) + Cl2 (g)

Recall that this equation shows the decomposition of phosphorus pentachloride.

We have the following equilibrium concentrations;

[PCI5]= 0.0095 M

[PCI3] = 0.020

[CI2] = 0.020 M

The equilibrium constant, K is obtained from;

K =  [PCI3]  [CI2]/[PCI5]

K = [0.020]^2/[0.0095]

K = 0.042

Answers

Answer:

Explanation:

Endo and Exo thermic are defined by what changes take place in the environment of the reaction.

If the temperature goes up, the reaction is giving up heat. It is Exothermic.

If the temperature goes down, the reaction requires heat. It is Endothermic.

In this case, the temperature went down. The reaction is Endothermic.

If 12.7 grams of hydrogen reacted with an unknown amount of oxygen, how many grams of water would be produced? (Write a balanced equation and show your work under the equation)

Answers

Answer:

    2H2    +   1 O2   ------>    2H2O

m = 12.7g                              m = ?

Get the number of moles for Hydrogen gas (H2) by dividing the mass by the molar mass (1.01g/mol as listed in the periodic table for its atomic mass)

12.7/1.01 = 12.57 mol of H2

Now use the mole to mole ratio of Hydrogen gas (H2) and water (H2O).

From the balanced equation, we can see that 2 mol of H2 gives us 2 mol of H2O. Since both of the ratios are equal (2:2), the moles we have for hydrogen gas is the same as the moles we get for water.

12.57 mol of H2O

Now that we have the amount of mol for H2O produced in this reaction, we can convert it to grams by multiplying the moles by the molar mass.

Molar mass of H2O = (1.01 x 2) + (16) = 18.02g/mol

12.57 x 18.02 = 226.5g (rounded)

Therefore 226.5g of water will be produced in this reaction

According to law of conservation of mass and stoichiometry, 114.3 g of water are produced if 12.7 grams of hydrogen reacted with an unknown amount of oxygen.

What is law of conservation of mass?

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

2 H₂ + O₂[tex]\rightarrow[/tex] 2 H₂O,according to this equation,4 g hydrogen reacts with 32 g oxygen to give 36 g water, thus 12.7 g of hydrogen will produce 12.7×36/4=114.3 g water and hence for this amount of water to be formed  12.7 g of hydrogen reacts with 101.6 g of oxygen which is obtained as 114.3-12.7=101.6 g

Thus, 114.3 g of water is produced.

Write out a correctly formatted hypothesis that describes how the amount of hydrogen gas produced with be affected by the concentration of acid.

Answers

When creating mixture the amount of hydrogen gas is directly related to the concentration of the acid mixture, the higher the concentration level The more hydrogen gas would be produced.

To solve such this we must know the concept of acid and base reaction. Therefore, the concentration of acid decides the concentration of hydrogen gas evolved.

What is chemical reaction?

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved.

what is the strongest interparticle force in a sample of so2?

Answers

Answer:

The strongest intermolecular force in sulfur dioxide is dipole-dipole forces.

Explanation:

The interparticle force in [tex]SO_{2}[/tex] (sulfur dioxide) is the dipole-dipole interaction.

What is  dipole-dipole interaction?

Dipole-dipole interaction is a type of intermolecular force that occurs between polar molecules. Polar molecules have a permanent dipole moment, which means they have a partial positive charge on one end and a partial negative charge on the other end. This creates an electrostatic attraction between the partial charges of neighboring molecules. The stronger the dipole moment of a molecule, the stronger its dipole-dipole interaction will be with other polar molecules.

Dipole-dipole interactions are responsible for a variety of physical properties of substances, including their boiling and melting points. Substances with strong dipole-dipole interactions tend to have higher boiling and melting points than substances with weaker interactions. In addition, the strength of dipole-dipole interactions can affect solubility, as polar substances tend to dissolve better in other polar substances due to their ability to form dipole-dipole interactions.

a vessel contains 66 g co2 and 16 g o2 at a pressure of 10.0 atm. what is the partial pressure of co2?

Answers

This question is providing the masses of carbon dioxide and oxygen gases at 10.0 atm as 66 g and 16 g respectively, and is asking for the partial pressure of the former which turns out to be 7.50 atm after doing the math.

Thus, we can start solving this problem with the Dalton's law approach, in order to make a relationship for the total pressure, partial pressure and mole fraction, which means we must first determine the mole fraction of carbon dioxide gas in the mixture as shown below:

[tex]x_{CO_2}=\frac{n_{CO_2}}{n_{CO_2}+n_{O_2}}[/tex]

Next, we calculate the moles of both gases by dividing the grams over the molar masses:

[tex]n_{CO_2}=\frac{66g}{44.01g/mol} =1.50mol\\\\n_{O_2}=\frac{16g}{32g/mol} =0.5mol[/tex]

Then, the mole fraction of carbon dioxide as the required one by plugging in the previously calculated moles:

[tex]x_{CO_2}=\frac{1.5}{1.5+0.5}=0.75[/tex]

Finally, we use the definition of the Dalton's law to calculate the partial pressure of carbon dioxide gas in the binary mixture:

[tex]P_{CO_2}=x_{CO_2}P\\\\P_{CO_2}=0.75*10.0atm\\\\P_{CO_2}=7.50 atm[/tex]
