When a volume of 60.0 mL of 0.200 M HBr is mixed with a volume of 30.0 mL of 0.400 M CH3NH2, The pH value is mathematically given as
pH=10.64
<h3>What is
the pH value when 60.0 mL of 0.200 M HBr is mixed with 30.0 mL of 0.400 M CH₃NH₂?</h3>
Question Parameters:
The pH when 60.0 mL of 0.200 M HBr
30.0 mL of 0.400 M CH₃NH₂ (Kb = 4.4 × 10^{-4}).
Generally, the equation for the Chemical Reaction is mathematically given as
H Br + H_3C NH_2----- > CH_3 NH_3 Br
Therefore
oH=p^{kb}+-log![\frac{salt}{base}](https://tex.z-dn.net/?f=%5Cfrac%7Bsalt%7D%7Bbase%7D)
OH=-log(4.4*10^{-4})+![\frac{0.1}{0.1}](https://tex.z-dn.net/?f=%5Cfrac%7B0.1%7D%7B0.1%7D)
OH=3.36
In conclusion, The equation pH value
pH+OH=14
Therefore
pH+=14-3.36
pH=10.64

Iron becomes rusted especially in damp air but never in a dry air, this is one of the many unique characteristics of iron. Iron is also ductile and malleable. It is found in the seventh group of the periodic table. It has four different and unique crystalline forms and completely dissolves in dilute acids. The two chemical compounds that can be found or made from iron are the bivalent iron also known as ferrous and the trivalent iron or known as ferric compounds.

Asymmetric Alkenes are treated with water in the presence of acid they follow
Markovnikoff rule, and the Hydrogen of incoming reagent goes to that carbon which contain more number of Hydrogen atoms. The reverse (
Anti-Markovnikoff) is done by carrying out Hydroboration reaction.In this case the Hydrogen atom of incoming reagent goes to that carbon which contains less number of Hydrogen atoms. In this reaction both -H and -OH adds in
syn fashion. The Hydroboration reaction of
Chloestrol is shown below,
Answer:
![n=0.430molH_2](https://tex.z-dn.net/?f=n%3D0.430molH_2)
Explanation:
Hello!
In this case, considering the partial Dalton's law of partial pressures, we can notice that the total pressure equals the pressure of steam and the pressure of hydrogen, which can be determined as shown below:
![p_T=p_H+p_w\\\\p_H=811torr-12torr=799torr*\frac{1atm}{760torr}\\\\p_H=1.05atm](https://tex.z-dn.net/?f=p_T%3Dp_H%2Bp_w%5C%5C%5C%5Cp_H%3D811torr-12torr%3D799torr%2A%5Cfrac%7B1atm%7D%7B760torr%7D%5C%5C%5C%5Cp_H%3D1.05atm)
Thus, by using the ideal gas law, we can compute the moles of hydrogen as shown below:
![PV=nRT\\\\n= \frac{PV}{RT}=\frac{1.05atm*10.0L}{0.082\frac{atm*L}{mol*K}*298K}\\\\n=0.430molH_2](https://tex.z-dn.net/?f=PV%3DnRT%5C%5C%5C%5Cn%3D%20%5Cfrac%7BPV%7D%7BRT%7D%3D%5Cfrac%7B1.05atm%2A10.0L%7D%7B0.082%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2A298K%7D%5C%5C%5C%5Cn%3D0.430molH_2)
