Answer:
a. Polar
b. Polar
c. Non-polar
d. Non-polar
Explanation:
a.
, hydronium cation contains a positive charge. Just as any other ion, it is polar, as it has a net charge.
b.
has the same shape as water. There are two lone pairs on sulfur atom which produce an overall dipole moment in this molecule, the bent structure is polar.
c.
is non-polar, as the central atom, phosphorus, doesn't contain any lone pairs, all the dipole moments cancel out: two dipole moments in the vertical plane, P-Cl, and three P-Cl dipoles in the horizontal plane within a trigonal bipyramidal shape.
d.
is non-polar, since it's a tetrahedral molecule with no lone pairs on carbon atom, all four C-F dipole moments cancel out to yield a net 0 dipole moment.
The unit of mass is 'Kilogram' which is written as 'kg' and volume, v = 10 L.
<h3>Equation :</h3>
To calculate the volume
Use formula,
density = mass / volume
density = 100 kg/L
mass = 1000 kg
volume = mass / density
v = 1000/100
v = 10 L
<h3>What is density mass?</h3>
A substance, material, or object's mass density is a measure of how much mass (or how many particles) it has in relation to the volume it occupies.

I understand the question you are looking for :
If you have a density of 100 kg/L, and a mass of 1000 units, tell me the following: First what are the mass units? Secondly, what is the volume?
Answer:
![1.75272\ \text{m}^3](https://tex.z-dn.net/?f=1.75272%5C%20%5Ctext%7Bm%7D%5E3)
Explanation:
The breakdown reaction of ozone is as follows
![CF_3Cl + UV \rightarrow CF_3 + Cl](https://tex.z-dn.net/?f=CF_3Cl%20%2B%20UV%20%5Crightarrow%20CF_3%20%2B%20Cl)
![Cl + O_3 \rightarrow ClO + O_2](https://tex.z-dn.net/?f=Cl%20%2B%20O_3%20%5Crightarrow%20ClO%20%2B%20O_2)
![O_3 + UV \rightarrow O_2 + O](https://tex.z-dn.net/?f=O_3%20%2B%20UV%20%5Crightarrow%20O_2%20%2B%20O)
![ClO + O \rightarrow Cl + O_2](https://tex.z-dn.net/?f=ClO%20%2B%20O%20%5Crightarrow%20Cl%20%2B%20O_2)
It can be seen that 2 moles of ozone is required in the complete cycle
So for 10 cycles, 20 moles of ozone is required
m = Mass of
= 15.5 g
M = Molar mass of
= 104.46 g/mol
P = Pressure = 24.5 mmHg
T = Temperature = 232 K
R = Gas constant = ![62.363\ \text{L mmHg/K mol}](https://tex.z-dn.net/?f=62.363%5C%20%5Ctext%7BL%20mmHg%2FK%20mol%7D)
Number of moles is given by
![n=\dfrac{m}{M}\\\Rightarrow n=\dfrac{15.5}{104.46}\\\Rightarrow n=0.1484\ \text{moles}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7Bm%7D%7BM%7D%5C%5C%5CRightarrow%20n%3D%5Cdfrac%7B15.5%7D%7B104.46%7D%5C%5C%5CRightarrow%20n%3D0.1484%5C%20%5Ctext%7Bmoles%7D)
![20\ \text{moles} = 20\times 0.1484 = 2.968\ \text{moles}](https://tex.z-dn.net/?f=20%5C%20%5Ctext%7Bmoles%7D%20%3D%2020%5Ctimes%200.1484%20%3D%202.968%5C%20%5Ctext%7Bmoles%7D)
From ideal gas law we have
![PV=nRT\\\Rightarrow V=\dfrac{nRT}{P}\\\Rightarrow V=\dfrac{2.968\times 62.363\times 232}{24.5}\\\Rightarrow V=1752.72\ \text{L}=1.75272\ \text{m}^3](https://tex.z-dn.net/?f=PV%3DnRT%5C%5C%5CRightarrow%20V%3D%5Cdfrac%7BnRT%7D%7BP%7D%5C%5C%5CRightarrow%20V%3D%5Cdfrac%7B2.968%5Ctimes%2062.363%5Ctimes%20232%7D%7B24.5%7D%5C%5C%5CRightarrow%20V%3D1752.72%5C%20%5Ctext%7BL%7D%3D1.75272%5C%20%5Ctext%7Bm%7D%5E3)
For 20 cycles of the reaction the volume of the ozone is
.
Answer:
There will be one Al3+ ion.
There will be 3 NO3- ions
Explanation:
Dissociation equation:
Al(NO₃)₃ → Al³⁺ + 3NO₃¹⁻
When aluminium nitrate dissociate it produces one silver ion (Al³⁺) and three (NO₃¹⁻) ions.
Properties of Al(NO₃)₃:
It is inorganic compound having molecular mass 169.87 g/mol.
It is white odor less compound.
Its density is 4.35 g/mL.
Its melting and boiling points are 120°C and 440°C.
It is soluble in water.
It is sued to treat infections.
It is used in the photographic films.
It s toxic and must be handled with great care.
