Any number below 7. 7 Is the neutral of the pH scale.
So the range is 0-7
Polar bond is formed by 2 non-metal atoms which have a significant difference in electronegativity.
Answer:
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
Answer:
Vaccines work by stimulating your immune system to produce antibodies, exactly like it would if you were exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.
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
