Answer:
Since all the acid molecules have split into ions, there will be more H+ ions in a strong acid than a weak acid, hence it's pH is lower! E.g. Hydrochloric acid HCl, nitric acid HNO3. If one mole of an acid is neutralised by 2 moles of NaOH, then the acid is dibasic!
Explanation:
hope it helps
good day
thank u ✌️
Answer: To determine the mole ratio
Explanation:
A balanced chemical equation is needed ,because it helps to determine the mole ratio of acid and base.
The mole ratio ensures that the number of moles of H+ provided by the acid is equal to number of moles of OH- ion provided by the base, For neutralization to occur, this must be the case.
Frequency = speed of light/wavelength
speed of light = ~ 3 x 10^8 m/s.
Your answer should be 4.002602!!!
