Answer:
One serving is 1/4 cup therefore 1 cup would be 4 servings. Since we have 9 cups we would then multiply 9 x 4 and the answer would be 36 servings. You have a ratio of cups to serving, so 1/4 cup : 1 serving, or .
Explanation:
Answer:
: conjugate acid of 
: conjugate base of 
: conjugate base of
: conjugate acid of
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
Here in forward reaction is accepting a proton, thus it is considered as a base and after accepting a proton, it forms which is a conjugate acid.
And is losing a proton, thus it is considered as an acid and after loosing a proton, it forms which is a conjugate base.
Similarly in the backward reaction, is loosing a proton, thus it is considered as a acid and after loosing a proton, it forms which is a conjugate base.
And is accepting a proton, thus it is considered as a base and after accepting a proton, it forms 
which is a conjugate acid.
