However many ounces you have, just multiply that by 28.34952. The answer to that is the conversion. so 5 ounces is 141.7476. Proof below.
Psolution = X · PH_20
= 0.966 · 31.8 torr
= 30.7 torr
Answer:
The answer to your question is:
Explanation:
Ionic compound is formed when a metal and a nonmetal are attached.
If we have MgX₂, that means that the nonmetal must have a valence of -1.
From the list the nonmetals with a valence of -1 are:
Bromine(Br) and fluorine(F).
Answer:
The answer is "2%"
Explanation:
Equation:
![HNO_2\ (aq) \leftrightharpoons H^{+} \ (aq) + NO_2^{-}\ (aq) \\\\\ K_a = 4.0\times \ 10^{-4}](https://tex.z-dn.net/?f=HNO_2%5C%20%28aq%29%20%5Cleftrightharpoons%20%20H%5E%7B%2B%7D%20%5C%20%28aq%29%20%2B%20NO_2%5E%7B-%7D%5C%20%28aq%29%20%5C%5C%5C%5C%5C%20%20K_a%20%3D%204.0%5Ctimes%20%5C%2010%5E%7B-4%7D)
![H^{+}=?](https://tex.z-dn.net/?f=H%5E%7B%2B%7D%3D%3F)
Formula:
![Ka = \frac{[H^{+}][NO_2^{-}]}{[HNO_2]}](https://tex.z-dn.net/?f=Ka%20%3D%20%5Cfrac%7B%5BH%5E%7B%2B%7D%5D%5BNO_2%5E%7B-%7D%5D%7D%7B%5BHNO_2%5D%7D)
Let
at equilibrium
![x^2 = (4.0\times 10^{-4})\times 1.0\\\\x = ((4.0\times 10^{-4})\times 1.0)^{0.5} = 2.0 \times 10^{-2} \ M\\\\](https://tex.z-dn.net/?f=x%5E2%20%3D%20%284.0%5Ctimes%2010%5E%7B-4%7D%29%5Ctimes%201.0%5C%5C%5C%5Cx%20%3D%20%28%284.0%5Ctimes%2010%5E%7B-4%7D%29%5Ctimes%201.0%29%5E%7B0.5%7D%20%3D%202.0%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20%20M%5C%5C%5C%5C)
therefore,
![[H^{+}] = 2.0\times 10^{-2} \ M = 0.02 \ M](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%202.0%5Ctimes%2010%5E%7B-2%7D%20%5C%20M%20%3D%200.02%20%5C%20M)
Calculating the % ionization:
![= \frac{([H^{+}]}{[HNO_2])} \times 100 \\\\= \frac{0.02}{1}\times 100 \\\\= 2\%\\\\](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B%28%5BH%5E%7B%2B%7D%5D%7D%7B%5BHNO_2%5D%29%7D%20%5Ctimes%20100%20%5C%5C%5C%5C%3D%20%5Cfrac%7B0.02%7D%7B1%7D%5Ctimes%20100%20%5C%5C%5C%5C%3D%202%5C%25%5C%5C%5C%5C)
A. True. The ozone layer is very critical to our health.
