Answer:
2.7 × 10⁻⁴ bar
Explanation:
Let's consider the following reaction at equilibrium.
SbCl₅(g) ⇄ SbCl₃(g) + Cl₂(g)
The pressure equilibrium constant (Kp) is 3.5 × 10⁻⁴. We can use these data and the partial pressures at equilibrium of SbCl₅ and SbCl₃, to find the partial pressure at equilibrium of Cl₂.
Kp = pSbCl₃ × pCl₂ / pSbCl₅
pCl₂ = Kp × pSbCl₅ / pSbCl₃
pCl₂ = 3.5 × 10⁻⁴ × 0.17 / 0.22
pCl₂ = 2.7 × 10⁻⁴ bar
Because if no one gets sick the hospitals will get no patients to cure and there would be overpopulation.
Answer:
The atomic number of an atom is the number of protons in the nucleus or the number of electrons in a neutral atom
Explanation:
Chemical formula of calcium sulfate dihydrate: CaSO₄ · 2 H₂O
There is a 1 : 2 mole ratio between calcium sulfate and water.
Explanation:
The calcium sulfate may be find as an anhydrous salt or a dihydrate. In the case of the dihydrate the chemical formula is CaSO₄ · 2 H₂O.
In the calcium sulfate dihydrate there are 1 mole of CaSO₄ and 2 moles of H₂O, so the mole ratio between the salt and the water molecules is 1 : 2.
