Bbgfbsthgbdvdge fr that’s crazy d. Thx
There are 30 inches in 2.5 just know that a foot is 12 inches so 12 times 2.5 is 30
Answer : The reactant acid and conjugate base in this reaction is, 
and 
.
Explanation :
Conjugate acid : A species that is formed by receiving of a proton 
by a base is known as conjugate acid.
Conjugate base : A species that is formed by donating of a proton by an acid is known as conjugate base.
The given chemical reaction is,
In this reaction, 
(base) react with (acid) to give 
(conjugate acid) and (conjugate base).
Therefore, the reactant acid and conjugate base in this reaction is, and .

So what have I done here? First, I had a balanced chemical equation (this is the important step; is it balanced?). Then I used the stoichiometry to get the molar quantity of product, and converted this molar quantity to mass. If this is not clear, I am willing to have another go.
