Consider the following reaction: SO2Cl2(g)⇌SO2(g)+Cl2(g) A reaction mixture is made containing an initial [SO2Cl2] of 2.2×10−2M . At equilibrium, [Cl2]= 1.3×10−2M . Calculate the value of the equilibrium constant (Kc).

Answers

Answer 1

Answer:

The value of equilibrium constant (Kc) will be 0.0188.

Equilibrium constant :

The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.

Given reaction:

SO₂Cl₂(g)⇌SO₂(g)+Cl₂(g)

To find:

Kc=?

The equation that represents kc for the given reaction will be:

$k_c=([SO_2][Cl_2])/([SO_2Cl_2])$

On substituting the initial concentration:

$k_c=([SO_2][Cl_2])/([SO_2Cl_2])\n\nk_c=([1.3*10^(-2)][1.3*10^(-2)])/([2.2*10^(-2)-1.3*10^(-2)]) \n\nk_c=0.0188$

Thus, the value of equilibrium constant (Kc)will be 0.0188.

Answer 2

Answer: The value of equilibrium constant is equal to the quotient of the products raised to its stoichiometric coefficient over the reaction's reactants raised to its respective stoichiometric coeff. The equation is Kc=[SO2][Cl2]/[SO2Cl2]= [1.3*10^-2][1.3*10^-2]/[2.2*10^-2-1.3*10^-2]=0.0188. The final answer is Kc=0.0188.

Which equation shows conservation of atoms?A) H2 + O 2 --> H2O
B) H2 + O 2 --> 2H2O
C) 2H2 + O2 --> 2H2O
D) 2H2 + 2O2 --> 2H2O

Answers

Answer: The equation showing conservation of atoms is $2H_2+O_2\rightarrow H_2O$

Explanation:

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.

For the given chemical equations:

Option A:

The given chemical equation follows:

$H_2+O_2\rightarrow H_2O$

There are 2 hydrogen atoms and 2 oxygen atoms on the reactant side and 2 hydrogen and 1 oxygen atom on product side.

So, this equation does not show conservation of atoms.

Option B:

The given chemical equation follows:

$H_2+O_2\rightarrow 2H_2O$

There are 2 hydrogen atoms and 2 oxygen atoms on the reactant side and 4 hydrogen atoms and 2 oxygen atoms on product side.

So, this equation does not show conservation of atoms.

Option C:

The given chemical equation follows:

$2H_2+O_2\rightarrow H_2O$

There are 4 hydrogen atoms and 2 oxygen atoms on the reactant side and 4 hydrogen atoms and 2 oxygen atoms on product side.

So, this equation shows conservation of atoms.

Option D:

The given chemical equation follows:

$2H_2+2O_2\rightarrow 2H_2O$

There are 4 hydrogen atoms and 4 oxygen atoms on the reactant side and 4 hydrogen atoms and 2 oxygen atoms on product side.

So, this equation does not show conservation of atoms.

Hence, the equation showing conservation of atoms is $2H_2+O_2\rightarrow H_2O$

What happens to energy during the formation of a solution?

Answers

The study of chemicals and bonds is called chemistry.

The correct answer is absorbed or released.

What is energy?

Energy is defined as the physical property which can be transferred from one body to another.
There are various types of energy present. A few examples are as follows:-
Heat energy, wind energy, light energy, etc.

Depending on the requirement of the solution, the compound can release energy to make a bond or can release energy to break the bond from the surrounding.

Hence, the correct answer is absorbed or released.

For more information about the energy, refer to the link:-

brainly.com/question/1932868

As the solute dissolves in the solvent,energy is absorbed and used to separate and break apart molecules. Once a solution is formed, this energyis released, increasing the temperature of the solution. ... The solution is saturated if it contains just enough of the solute that the solvent can hold.

The average speed of a nitrogen molecule in air at 25 °C is 515 m/s. Convert this speed to miles per hour.

Answers

Answer:

1151.08miles/h

Explanation:

The given speed is 515 m/s

To convert meters per second to miles per hour:

Convert meters to miles: 1 m = 0.000621371 miles

Convert seconds to hours: 1 hr = 3600 s

Plug into the formula: miles/hr = (m/s) * (0.000621371 miles/m) * (3600 s/hr)

Plugging in the numbers: miles/hr = (515 m/s) * (0.000621371 miles/m) * (3600 s/hr) miles/hr = 1151.08miles/h

Therefore, the average speed of a nitrogen molecule in air at 25 °C converted to miles per hour is 1151.08miles/h.

Final answer:

To convert the average speed of a nitrogen molecule in air from meters per second to miles per hour, first convert the speed from meters per second to kilometers per hour, and then convert from kilometers per hour to miles per hour.

Explanation:

To convert the average speed of a nitrogen molecule in air from meters per second to miles per hour, we can use the conversion factor 1 mile = 1609.34 meters and 1 hour = 3600 seconds.

First, let's convert the speed from meters per second to kilometers per hour. We divide the speed in meters per second by 1000 to get the speed in kilometers per second and then multiply by 3600 to get the speed in kilometers per hour. This gives us a speed of approximately 1850 km/h.

Next, we convert the speed from kilometers per hour to miles per hour by dividing the speed in kilometers per hour by 1.60934. This gives us a speed of approximately 1150 mph.
