The kinetic energy of an object depends on two factors: mass(m) and velocity(v). The mass of an object can be measured in kilograms(kg) and velocity of the object in meters per second(m/s).

Using lewis formulas, assign oxidation states to the atoms in these compounds. assume that sulfur is more electronegative than c

lilavasa [31]

Compound 1: CS₂

Oxidation State of S = -2

Overall Charge on Molecule = 0

So,
C + (-2)₂ = 0

C -4 = 0

C = +4
Result:
O.S of C = +4

O.S of S = -2

Compound 2: CH₃S-S-CH₃ or H₆C₂S₂

Oxidation State of H =  +1

Oxidation State of S =  -2

Overall Charge on Molecule = 0
So,
(H)₆ + (C)₂ + (S)₂  = 0

(+1)₆ + (C)₂ + (-2)₂  = 0

+6 + (C)₂ -4 = 0

(C)₂ = -6 + 4

(C)₂ = -2

C = -1
Result:
    O.S of C  =  -1

  O.S of S  =  -2

  O.S of H  =  +1

Ammonium hydrogen sulfide decomposes according to the following reaction, for which Kp = 0.11 at 250°C: NH4HS(s) ⇌ H2S(g) + NH3(

Scrat [10]

Answer:

0,33atm

Explanation:

For the reaction:

NH₄HS(s) ⇌ H₂S(g) + NH₃(g)

kp is defined as:

kp = 0.11 = P(H₂S) P(NH₃) (1)

Where P(H₂S) and P(NH₃) are partial pressures of each compound.

In equilibrium, if in your system the only addition is of NH₄HS(s), the partial pressures and the concentration of each compound are:

NH₄HS: I - x

-Where I is an initial concentration that is not relevant for the problem and x is the NH₄HS that reacts-

H₂S(g): x

NH₃(g): x

Replacing in (1):

0.11 = X×X

0.11 = X²

0.33 = X

That means P(NH₃) is 0.33 atm

I hope it helps!
