A sample of solid NH 4HS is placed in a closed vessel and allowed to equilibrate. Calculate the equilibrium partial pressure (at
UNO [17]

Answer:

The answer to the question is

The equilibrium partial pressure (atm) of ammonia, assuming that some solid NH₄HS remains 0.26 atm.

Explanation:

To solve the question, we write out the chemical equation as follows

NH₄HS (s) ⇄ NH₃ (g) + H₂S (g)

From the above equation, it is observed that only the gaseous products contribute to the partial pressure

Kp =PNH₃·PH₂S where at Kp = 0.070 and PNH₃, PH₂S are the partial pressures of the gases

However since the number of moles of both gases are equal, therefore by Avogadro's law PNH₃ = PH₂S

Then PNH₃  = √(0.07) = PH₂S = 0.2645 atm. ≅ 0.26 atm.

Which type of bond will form between two chlorine atoms?
beks73 [17]
The link between the same atom is always non-polar Covalent.Is Covalent because there is no possibility of an atom donating electrons to the other, since they are equal and need the same number of electrons, and is why the formal charge non-polar (electronegativity) of two atoms is equal. When there is no difference of formal charges (dipole moment) between the atoms, the connection is always apolar.

hope this helps!

Give an example of a substance that is MORE dense in its solid state when compared to its liquid state.
Natalka [10]

Answer: Wax

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Usually solids are more denser than liquid, as molecules in solid are more strongly packed and thus have more mass per unit volume.

Liquids on the other hand contain molecules which are less tightly bound and thus thus contain less mass per unit volume as compared to solid.

Example: Solid wax is more denser than liquid wax.
