Answer:

Trigonal Pyramidal

Explanation:

In PCl₃, between P and Cl, P is the less electronegative atom and so is the central atom. A pair of electron is shared between P and Cl thus forming a P-Cl covalent bond. There are a total of three P-Cl covalent bonds in PCl₃. And since P has 5 valence electrons P has a one lone pair of electron and the three covalent bonds. Also P has three sp³ hybird orbital and one p orbital containing a lone pair of electron. thus the molecular geometry, or shape, of phosphorus trichloride PCl₃ is trigonal pyramidal.

I believe the molecular geometry of PCL3 would be trigonal planar.

If 17. 6 g of hcl are used to produce a 14. 5 l solution, what is the ph of the solution?.

kati45 [8]

This problem is providing us with the mass of hydrochloric acid and the volume of solution and asks for the pH of the resulting solution, which turns out to be 1.477.

<h3>pH calculations</h3>

In chemistry, one can calculate the pH of a solution by firstly obtaining its molarity as the division of the moles of solute by the liters of solution, so in this case for HCl we have:

$M=\frac{17.6g*\frac{1mol}{36.46g} }{14.5L} \\\\M=0.0333 M$

Next, due to the fact that hydrochloric acid is a strong acid, we realize its concentration is nearly the same to the released hydrogen ions to the solution upon ionization. Thereby, the resulting pH is:

$pH=-log(0.0333)\\\\pH=1.477$

Which conserves as much decimals as significant figures in the molarity.

To three significant digit,what is the mass percentage of iron in the compound Fe2O3

svlad2 [7]

69.9%

Explanation:

To find the mass percentage of iron in the compound in Fe₂O₃, we would go ahead to express the given molar mass of the iron to that of the compound.

Mass percentage = $\frac{molar mass of Fe}{Molar mass of Fe_{2}O_{3} }$ x 100

Molar mass of Fe = 55.85g/mol

Molar mass of O = 16g/mol

Molar mass of Fe₂O₃ = 2(55.85) + 3(16) = 159.7‬g/mol

Mass percentage = $\frac{2(55.85)}{159.7} x 100$ = 69.94% = 69.9%
