Answer : 2.14

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

Given : NaOH\rightarrow Na^++OH^-

1 mole of NaOH gives 1 mole of OH^_

Thus 0.0072 moles of  NaOH will give= 0.0072 moles of OH^_

pOH=-\log [OH^]

pOH=-\log (0.0072)

pOH=2.14

Therefore, the pOH of the basic solution is 2.14.

What is the ph of 0.45m solution of the strong chloric acid HCIO3?​
AnnZ [28]

Answer:

pH = 0.35

Explanation:

For a strong acid, all of the acid dissociates into H3O+, and pH = -log[H3O+], where [H3O+] = [HClO3] = 0.45 M.

If 3 moles of H2 react with two moles of o2 what is limiting reactant
Dominik [7]

H₂ is the limiting reactant.

<u>Explanation:</u>

H₂  reacts with O₂

The reaction would be

2H₂ + O₂ → 2H₂O

According to the balanced equation, 2 moles of H₂ reacts with 1 mole of O₂ to form 2 moles of H₂O.

The ratio of usage of H₂ and O₂ is 2 : 1 respectively

If 3 moles of H₂ and 2 moles of O₂ are present then:

3 moles of H₂ would require 1.5 moles of O₂                 ( 2 : 1 of H₂ and O₂ )

Out of 2 moles of O₂, 1.5 moles would be used and 0.5 mole would be in excess.

Therefore, H₂ is the limiting reactant as the number of moles of H₂ are not enough to use all the O₂.
