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.
<span>M(HCl) * </span><span>V(HCl) </span>= <span>M(NaOH) * </span><span>V(<span>NaO<span>H)
</span></span></span>
M(HCl) = 0.35
<span>V(HCl) = 45mL
</span>M(NaOH)= 0.35
now, solne for V(NaOH) by putting these values in the above equation.
M(HCl) * <span>V(HCl) </span>= <span>M(NaOH) * </span><span>V(NaOH)</span>
<span>0.35 * 45 = 0.35 * V(NaOH)</span>
<span>V(NaOH) = 45 mL</span>

Answer:
Explanation:
Given that,
The distance between the centers of the two oxygen atoms in an oxygen molecule is 
.
We need to convert this distance in inches.
We know that,
1 cm = 0.393 inches
We can solve it as follows :
So, the distance between the centers of the two oxygen atoms is 
.
