Answer:
The pOH of the solution is 9.92
Explanation:
pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance. PH is defined as the negative logarithm (base 10) of the hydronium ion concentration [H₃O⁺]:
pH= - log [H₃O⁺]
So, if [H₃O⁺]=8.26*10⁻⁵, the pH is: pH=- log (8.26*10⁻⁵) ⇒ pH= 4.08
The pOH measures the concentration of OH− ions. The following relationship can be established between pH and pOH:
pH + pOH= 14
In this case, being pH=4.08 and replacing in the relationship between pH and pOH:
4.08 + pOH=14
Solving:
pOH= 14 - 4.08
pOH= 9.92
The pOH of the solution is 9.92
Answer:
(b) When 20.0 g of nitrogen and 32.0 g of oxygen are combined and allowed to react in two separate experiments, both times the product isolated from reaction contains 14.0 g of nitrogen and 32.0 g of oxygen.
Explanation:
The law of definite proportion states that a gen chemical compound always contains its constituent elements in a fixed ratio by mass, independent on the method of preparation.
The molar mass of Nitrogen and Oxygen would always remain the same, allowing for exact reactant masses (or mole ratio) irrespective of the given amount of sample.
