A 2.5 mol sample of phosphorus pentachloride, PCl5 dissociates at 160C and 1.00atm to give 0.338 mol of phosphorus trichloride a
Readme [11.4K]

Explanation:

Moles of phosphorus pentachloride present initially = 2.5 mol

Moles of phosphorus trichloride at equilibrium = 0.338 mol

PCl_5\rightleftharpoons PCl_3+Cl_2

Initially

2.5 mol      0    0

At equilibrium:

(2.5 - x) mol      x     x

So, from above, the moles of phosphorus trichloride at equilibrium , x= 0.338 mol

Mass of 0.338 moles of  phosphorus trichloride at equilibrium:

= 0.338 mol × 137.5 g/mol = 46.475 g

Moles of phosphorus pentachloride present at equilibrium :

= (2.5 - 0.338) mol = 2.162 mol

Mass of 2.162 moles of  phosphorus pentachloride at equilibrium:

= 2.162 mol × 208.5 g/mol = 450.777 g

Moles of chloride gas present at equilibrium : 0.338 mol

Mass of 0.338 moles of chloride gas at equilibrium:

= 0.338 mol × 71 g/mol = 23.998 g

Answer:

I got you... 2 amino acids are linked to each other by a peptide linkage. A peptide linkage is formed when carboxyl group of one amino acid combine with the amine group of the other and during this process, a water molecule is removed.  

The given tripeptide will have 2 peptide bonds. To draw the structure of given tripeptide, we will arrange them in the given order and then we will remove 2 water molecules to form 2 peptide bonds.

Which new diagnosis would prompt the provider to discontinue a prn order for magnesium hydroxide? group of answer choices renal
dusya [7]

Renal failure is the new diagnosis that the provider would prompt to discontinue a PRN order for magnesium hydroxide.

<h3>What is Renal failure?</h3>

Renal failure is a special condition where the person is unable to manage the function of the kidney organ.

The magnesium hydroxide may cause renal failure because this salt must be eliminated by the kidney and therefore it may trigger health complications.

In conclusion, renal failure is the new diagnosis that the provider would prompt to discontinue a PRN order for magnesium hydroxide.
