Not gonna lie.....I need help with this my guy.

At a certain temperature, the K p Kp for the decomposition of H 2 S H2S is 0.746 0.746 . H 2 S ( g ) − ⇀ ↽ − H 2 ( g ) + S ( g )

Ivanshal [37]

Answer: The total pressure of container at equilibrium is 0.431 bar

Explanation:

We are given:

Pressure of hydrogen sulfide = 0.240 bar

The given chemical equation follows:

$H_2S(g)\rightleftharpoons H_2(g)+S(g)$

Initial: 0.240

At eqllm: 0.240-x x x

The expression of $K_p$ for above equation follows:

$K_p=\frac{p_{H_2}\times p_S}{p_{H_2S}}$

We are given:

$K_p=0.746$

Putting values in above expression, we get:

$0.746=\frac{x\times x}{0.240-x}\\\\x=0.191,-0.940$

Neglecting the negative value of 'x' because pressure cannot be negative.

So, the equilibrium pressure of hydrogen gas = x = 0.191 bar

The equilibrium pressure of sulfur gas = x = 0.191 bar

The equilibrium pressure of hydrogen sulfide gas = (0.240 - x) = (0.240 - 0.191) = 0.049 bar

Total pressure of the container at equilibrium = $p_{H_2}+p_{S}+p_{H_2S}$

Total pressure of the container at equilibrium = 0.191 + 0.191 + 0.049 = 0.431 bar

Hence, the total pressure of container at equilibrium is 0.431 bar

What is the molartity of 2 moles of a compound dissolved in 4 L of water

bogdanovich [222]

Number of moles = 2 moles

Volume = 4 L

M = n / V

M = 2 / 4

M = 0,5 mol/L

hope this helps!

State, in terms of subatomic particles, how an atom of C-13 is different from an atom of C-12

mariarad [96]

C-12 and C-13 are isotopes of the element carbon. Since they are both of the same element, they have the same number of protons. The number that follows the C indicates the number of neutrons. Isotopes are variations of the element with different number of neutrons. C-12 shows that that variation of carbon has 6 protons and 6 neutrons for a total mass of 12. C-13 shows that it has 6 protons but 7 neutrons for a total mass of 13

A balloon (approximate as a sphere)

Dahasolnce [82]

1. Fill the balloon with water, then weigh it. The volume is then: Volume (cm^3) = Weight(gm)/1(gm/cm^3), (neglecting the weight of the empty balloon.)

What is a specialised cell?

Arlecino [84]

Answer:

Hello, how is your day?

Explanation:

Specialised cells have a specific role to perform. Each specialised cell has a different job to do. They have special features that allow them to do these jobs. Muscle cells, for example, are held together in bundles, which pull together to make muscles contract.
