Given:
0.607 mol of the weak acid
0.609 naa
2.00 liters of solution
The solution for finding the ph of a buffer:
[HA] = 0.607 / 2.00 = 0.3035 M
[A-]= 0.609/ 2.00 = 0.3045 M
pKa = 6.25
pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
B will be the one I think tbh
A bright feild is most commonly used
Similar - Both are organic compounds and fossil fuels
Different - natural gas is made up of lighter organic compounds than petrolium
When publishing experimental results, it is always advisable to have your peer review those results. This peer can confirm the results that you got and thus they will be more reliable.
Also, you will be sure that what what you are publishing is correctly presented as it is always good to have a fresh eya to double-check what is written.
