Hello!
The H₃O⁺ concentration can be found using the definition of pH and clearing the equation for [H₃O⁺]. The solution has a pH lower than 7, so the Sauvignon Blanc is
acid. The calculation for [H₃O⁺] is shown below:
![pH=-log [H_3O^{+}]](https://tex.z-dn.net/?f=pH%3D-log%20%5BH_3O%5E%7B%2B%7D%5D%20)
![[H_3O^{+}]= 10^{-pH}=10^{-3,24}=0,00058M](https://tex.z-dn.net/?f=%5BH_3O%5E%7B%2B%7D%5D%3D%2010%5E%7B-pH%7D%3D10%5E%7B-3%2C24%7D%3D0%2C00058M%20)
So, the concentration of H₃O⁺ in a Sauvignon Blanc with a pH of 3,24 is
0,00058 MHave a nice day!
Answer:- 3.12 g carbon tetrachloride are needed.
Solution:- The balanced equation is:
![CH_4+CCl_4\rightarrow 2CH_2Cl_2](https://tex.z-dn.net/?f=CH_4%2BCCl_4%5Crightarrow%202CH_2Cl_2)
From given actual yield and percent yield we will calculate the theoretical yield that would be further used to calculate the grams of carbon tetrachloride.
percent yield formula is:
percent yield = ![(\frac{actual}{theoretical})100](https://tex.z-dn.net/?f=%28%5Cfrac%7Bactual%7D%7Btheoretical%7D%29100)
![65.5=(\frac{2.25}{theoretical})100](https://tex.z-dn.net/?f=65.5%3D%28%5Cfrac%7B2.25%7D%7Btheoretical%7D%29100)
![theoretical=(\frac{2.25(100)}{65.5})](https://tex.z-dn.net/?f=theoretical%3D%28%5Cfrac%7B2.25%28100%29%7D%7B65.5%7D%29)
theoretical = 3.44 g
From balanced equation, there is 2:1 mol ratio between dichloethane and carbon tetrachloride.
Molar mass of dichloroethane is 84.93 gram per mol and molar mass of carbon tetrachloride is 153.82 gram per mol.
![3.44gCH_2Cl_2(\frac{1molCH_2Cl_2}{84.93gCH_2Cl_2})(\frac{1molCCl_4}{2molCH_2Cl_2})(\frac{153.82gCCl_4}{1molCCl_4})](https://tex.z-dn.net/?f=3.44gCH_2Cl_2%28%5Cfrac%7B1molCH_2Cl_2%7D%7B84.93gCH_2Cl_2%7D%29%28%5Cfrac%7B1molCCl_4%7D%7B2molCH_2Cl_2%7D%29%28%5Cfrac%7B153.82gCCl_4%7D%7B1molCCl_4%7D%29)
= ![3.12gCCl_4](https://tex.z-dn.net/?f=3.12gCCl_4)
So, 3.12 grams of carbon tetrachloride are needed to be reacted.
The answer would be 4.
The agencies are:
Department of Agriculture's Forest Service (AFS)
Department of the Interior's Bureau of Land Management (BLM)
Fish and Wildlife Service (FWS)
National Park Service (NPS)
These four agencies cover around 95% of the land and are the only federal agencies.
I learned about these agencies in school.
I think is False! Because it is not example of a disaccharide it is not saccharin-aspartame molecule.
Answer:
The answer is "Choice A and Choice B"
Explanation:
The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.
Let the Rate = k
As
doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.
By the rate
the created based and the reaction rate is about the same.
