Answer:

1.125

Explanation:

I think it is his because if you add 0.30 and 0.15 it adds up to 0.45 so you just multiply 0.45 and 2.5 and then it gives you 1.125. HOPE IT HELPS.

Given a chemical equation, showing the dissociation of an acid in solution, be able to identify the "acid", the "base", the "con

Karo-lina-s [1.5K]

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
A base is defined as a substance which accepts protons and thus forming conjugate acid.

$HA+H_2O\rightarrow A^-+H_3O^+$

Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.

HA = Acid

$H_2O$ = Base
