Let us write succinic acids as H2Suc
The first ionization is
H2Suc ----> HSuc- + H+
The seond ionization is
HSuc- ----> Suc-2 + H+
Calculate the H+ concentration of from the first ionization using pKa1.
Then, calculate the H+ concentration from the second ionization using pKa2.
Next, use the buffer equation to calculate the concentration of the salt in the solution. Then, use the given volume to get the number of moles of the salt. Finally, use the given molecular weight to get the mass.
Answer:
0.5 mole of a SO2 contains 3.01 into 10 ^23 molecules of So2.

Answer:
D. C=O
Explanation:
Esters are formed by the condensation of alcohols and acids with minus water. During the reaction, at least one -OH group is replaced by an O- alkyl group. The resulting compound is an ester and has a characteristic fruity smell. Its functional group is C=O
Answer:
Correct answer is Option A:
A. ethylene oxide (oxirane)
Explanation:
It reacts faster because it leads to a tertiary cation.
Answer:
397782000 m²
Explanation:
Given data:
123000 m × 3234 m =?
Solution:
123000 m × 3234 m = 397782000 m²
when we multiply the given quantities having same unit i.e meter the answer should be m² . It could be the area, and its unit is m².
Area = length (m) × width (m)
