Answer:
To determine the value of Kp for the given equilibrium, we need to use the partial pressures of the gases involved.
In the balanced equation: 2 HI (g) ⇌ H₂ (g) + I₂ (g), the stoichiometric coefficients are 2, 1, and 1 respectively.
At equilibrium, the expression for Kp is given by:
Kp = (P(H₂) * P(I₂)) / (P(HI)²)
Using the provided partial pressures:
P(HI) = 1.9 atm
P(H₂) = 7.9 atm
P(I₂) = 2.3 atm
Substituting these values into the expression for Kp:
Kp = (7.9 * 2.3) / (1.9²)
Kp ≈ 19.5 / 3.61
Calculating the result:
Kp ≈ 5.4
Therefore, the value of Kp for the given equilibrium is approximately 5.4.

What is an ecosystem?
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:
ksp = 0,176
Explanation:
The borax (Na₂borate) in water is in equilibrium, thus:
Na₂borate(s) ⇄ borate²⁻(aq) + 2Na⁺(aq)
When you add just borax, the moles of Na²⁺ are twice the moles of borate²⁻, that means 2borate²⁻=Na⁺ (1)
The ksp is defined as:
ksp = [borate²⁻] [Na⁺]²
Then, borate²⁻(B₄O₇²⁻) reacts with HCl thus:
B₄O₇²⁻ + 2HCl + 5H₂O → 4H₃BO₃ + 2Cl⁻
The moles of HCl that reacts with B₄O₇²⁻ are:
0,500M×0,01200L = 6,00x10⁻³ mol of HCl
As two moles of HCl react with 1 mol of B₄O₇²⁻, the moles of B₄O₇²⁻ are:
6,00x10⁻³ mol of HCl× = 3,00x10⁻³ mol of B₄O₇²⁻
For (1), moles of Na⁺ are 3,00x10⁻³ mol ×2 = 6,00x10⁻³ mol of Na⁺
The [borate²⁻] is 3,00x10⁻³ mol of B₄O₇²⁻/0,00850L = 0,353M
And [Na⁺] is 6,00x10⁻³ mol of Na⁺ / 0,00850L = 0,706M
Replacing in the expression of ksp:
ksp = [0,353] [0,706]²
ksp = 0,176
I hope it helps!

Answer:
Because as the concentration is diminished, the capacity to transfer electricity is diminished as well.
Explanation:
Hello!
In this case, since electrolytes are substances that are able to conduct the electricity in aqueous media (solutions in which water is the the solvent) because they have the capacity to form ions with both positive and negative charges, due to the fact that HCl is a strong acid, we notice it is fully ionized in solution and therefore it is a strong electrolyte. However, when the concentration is diminished, we can notice that strength is diminished as well because less ions will have the capacity to transfer the electricity and therefore it'd become a poor conductor or weak electrolyte.
Best regards!
