<u>Answer:</u> The value of K_p is 324

<u>Explanation:</u>

We are given:

Initial pressure of S_8(g) = 1.00 atm

The chemical equation for the conversion of S_8(g) to S_2(g) follows:

                  S_8(g)\rightleftharpoons 4S_2(g)

<u>Initial:</u>          1

<u>At eqllm:</u>    1-x       4x

We are given:

Equilibrium partial pressure of S_8(g)=0.25atm

Evaluating the value of 'x', we get:

\Rightarrow (1-x)=0.25\\\\\Rightarrow x=1-0.25=0.75

The expression of K_p for the above reaction follows:

K_p=\frac{(p_{S_2})^4}{p_{S_8}}

p_{S_2}=4x=(4\times 0.75)=3atm

p_{S_8}=0.25atm

Putting values in above expression, we get:

K_p=\frac{3^4}{0.25}\\\\K_p=324

Hence, the value of K_p is 324

What is the molarity of an HCl solution if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid
Sveta_85 [38]

Answer: The molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.

Explanation:

Given: V_{1} = 43.6 mL,      M_{1} = 0.125 M

V_{2} = 25.0 mL,        M_{2} = ?

Formula used to calculate the concentration of acid is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula.

M_{1}V_{1} = M_{2}V_{2}\\0.125 M \times 43.6 mL = M_{2} \times 25.0 mL\\M_{2} = 0.218 M

Thus, we can conclude that the molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.

Calculate the answer. Express it in scientific notation and include the correct number of significant figures. (12 x 104 ) x (5
ipn [44]

Answer:

Explanation:

(12 x 104 ) x (5 x 10-²) = 6 x 10 ³ 6 x 105 6.0x10²

1.  (12 x 104 ) = 1248 or 1.248 x 10^3

2.  (1.248 x 10^3)(5 x 10^-2) = 6.240 x 10^1 or 60 rounded to 1 sig fig

I don't understand "= 6 x 10 ³ 6 x 105 6.0x10² "

A reversible reaction is a reaction that takes place in the ( formation of reactants to products and products to reactants simultaneously ). If the reaction were to ( be in dynamic equilibrium ), the rate of forward reaction would be equal to that of the reverse reaction.

hope this helps :))

How are vibrations different between bigger sizes rubber bands and smaller sized rubber bands?
arlik [135]
Assuming the kind of vibration you are talking about is the kind where you stretch the rubber band between two points and then "twang" it, then the answer is fairly complex. What happens when you cause the vibrations to start is you make something called a "standing wave". In a standing wave, each particle in the rubber band has a certain amount of energy which causes it to move backwards and forwards, the particles with more energy have a larger "amplitude" (how much they move), and of course the particles with less energy have a smaller amplitude. Now a standing wave has two main components: The amplitude, and the frequency. The amplitude of the whole wave refers to the largest amplitude any particles has. The frequency refers to how often it takes for one of the particles to move between the two furthest away points it can be.
To compare rubber bands, you must remember to keep certain things constant. If you're looking at their vibrations, the amount of energy you use to "twang" the rubber band should be the same each time you twang it (which is the same as applying the same force each time you twang it).

A larger rubber band has more area over which to spread the energy, as well as it has more mass for the energy to move, so the vibrations will have smaller amplitudes, and smaller frequencies, overall vibrating less and with smaller vibrations.

Ion-ion forces

Nt has two valence electrons, and bonds with F to form NtF2. This means that the ion form of Nt is Nt2+. This means that NtF2 is an ionic compound.
