1.How could you determine the pH range over which a particular buffer system works best? 2.What are the pKa values for the various species of phosphoric acid and associated ions? Do your results agree with these values? Explain. 3.Provide an explanation for the shape of your graph for the Weak Acid/Strong Base titration. 4.Label the equivalence point/s, half equivalence points (corresponding to the pKas of phosphoric acid) and any buffer zones on your graph.

for points guys

answer: mole of the gas

answer: mole of the gasexplanation:

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
