The product of a number and 4 is 32
Answer:
NaOH
Explanation:
The sodium hydroxide is strongest base because it fully dissociate into ions.
It dissociate to gives the sodium and hydroxyl ions and solution became more basic.
NaOH → Na⁺(aq) + OH⁻(aq)
Its pH is 12. It is also known as caustic soda.
Other given Options:
The pH of blood is vary from 7.35 - 7.45. it is slightly alkaline.
The pH of HCl is 3.
The pH of saliva is 6.2 - 7.6.
We know that neutral pH is 7 the pH less than 7 is acidic so HCl is acidic because its pH is 3.
The pH is greater then 7 is basic so saliva and blood are basic but less than the NaOH.

Explanation:
Answer:
The half life time of first order reaction is 1.3 sec
Explanation:
Given:
First order rate constant

Initial concentration
M
From the formula of first order half life time,

So half life time is given by,

sec
Therefore, the half life time of first order reaction is 1.3 sec.
