Answer: Please see below for answers
Explanation: Matching appropriate labels , we have
1)3/4 of the way to second equivalence point of a diprotic acid/strong base titration-- pH=pka₂
equivalence point of a weak base/strong acid titration=pH<7
equivalence point of a strong acid/strong base titration= pH=7
equivalence point of a weak acid/strong base titration=pH>7
half-way to equivalence point of a weak acid/strong base titration pH =pka
where
pH gives the measure of the amount of concentration of hydrogen ions in an aqueous solution.
pKa is known as acid dissociation constant which explains the equilibrum at which a chemical species can give out or receive proton
pka₂ is the acid dissociation constant for the second ionization energy.
Bc the time changes that is the answer hoped i helped
Answer:
Change in volume on changing temperature from 33
to 5 is 5.49 mL
Explanation:
Initial volume of gas = V = 60 mL
Assuming final volume of gas to be V' mL
Initial temperature = T = 33 = 306 K
Final temperature = T' = 5 = 278 K
The relationship between volume and temperature of gas at constant pressure is shown below
Change in volume on changing temperature = 5.49 mL
Economic concerns is the correct one
The answer is (a.) more solid
Adding hydrogen atoms to an unsaturated fatty
acid will make it more solid. This process is called hydrogenation. In this
process, hydrogen is added to an unsaturated fatty acid to make it more
saturated and thereby more solid at a room temperature.
