POH = pKb + log [salt] / [base] ---> Basic Buffer
and pH = 14 - pOH
to predict the relative concentrations of the buffer components you need to know both pKb and pH...
While in this case only pKb is given and the pH of buffer is not given. So, nothing can be concluded about the relative concentrations of CH₃NH₂ and CH₃NH₃Cl
Answer:
Explanation:
Given:
Initial volume of the balloon V1 = 348 mL
Initial temperature of the balloon T1 = 255C
Final volume of the balloon V2 = 322 mL
Final temperature of the balloon T2 =
To calculate T1 in kelvin
T1= 25+273=298K
Based on Charles law, which states that the volume of a given mass of a ideal gas is directly proportional to the temperature provided that the pressure is constant. It can be applied using the below formula
T2=( V2*T1)/V1
T2=(322*298)/348
Hence, the temperature of the freezer is 276 K
Answer:
first of all we have to put sugar in bread and we have to add some ginger paste over it
Answer:
ethyl ethanoate and water
Explanation:
At the point when one fluid doesn't blend in with another yet glides on top of it, an isolating pipe can be utilized to isolate the two fluids. Oil glides on water. This combination can be isolated utilizing an isolating channel as demonstrated on the following page.
Ethyl liquor and water are two miscible fluids.
Refining is a cycle that can be utilized to isolate an unadulterated fluid from a combination of fluids. An isolating channel can be utilized to isolate the parts of the combination of immiscible fluids.
The answer is ethyl ethanoate and water. Hope this helps you!
