Answer:
4046atm
Explanation:
For this question you can use the ideal gas law,
<em /><em />
Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.
Because of the units given, R will equal .08026
Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):
This will give you:
Answer:
See explanation and image attached
Explanation:
My aim is to convert 1-bromobutane to butanal. The first step is to react the 1-bromobutane substrate with water. This reaction occurs by SN2 mechanism to yield 1-butanol. Hence reagent A is water.
1-butanol is now reacted with an oxidizing agent such as acidified K2Cr2O7 (reagent B) to yield butanal. Note that primary alkanols are oxidized to alkanals.
These sequence of reactions are shown in the image attached.
The question is incomplete, the complete question is:
Standardization of a Borax solution (Na2B4O7). A student titrates a 20.00 mL sample of an aqueous borax solution with 1.044 M H2SO4. It takes 2.63 mL of acid to reach the equivalence point. Knowing it takes 1 H2SO4 to neutralize 2 Na2B4O7, what was the concentration of this Borax solution?
<u>Answer: </u>The concentration of borax solution is 0.069 M.
<u>Explanation:</u>
To calculate the concentration of borax solution, the formula used is:
....(1)
where,
are the n-factor, concentration and volume of sulfuric acid
are the n-factor, concentration and volume of borax solution.
We are given:
Putting values in equation 1, we get:
Hence, the concentration of borax solution is 0.069 M.
