Catastrophic events create necessary safety requirements
Answer:
I think it's Dmitri Mendeleev
Explanation:
The giant smoke cloud would flood the sky and that would block off the sun and cut off photosynthesis. Which would me food production would cut down and more.
Hope this helps
Dissociation of para-bromobenzoic acid can be represented as:
4-BrC₆H₄COOH----->4-BrC₆H₄COO⁻ + H⁺
Dissociation constant of this acid can be calculated as:
Ka={[BrC₆H₄COO⁻][H⁺]}/[4-BrC₆H₄COOH]
as[4-BrC₆H₄COOH=Concentration of para- bromobenzoic acid=0.35 M
And as 1.69% of this acid dissociates to form [BrC₆H₄COO⁻] and [H⁺], so amount of these ions formed will be:
[BrC₆H₄COO⁻]=[H⁺]=1.69×0.35=0.59
So Now Ka=(0.59×0.59)/0.35
=0.99.
Based on your question where there is a concentration of 1 M, the weak acid HN02 is 2% ionized nad the PH of the solution is 1.2. The possibilities that could happen to KNO2(s) if it will dissolved into the solution is that w<span>hen more nitrite is added to the solution, the reaction will shift towards the reactants because of La Châtelier's principle. In doing this, the solution will decrease in hydronium concentration and therefore the pH will increase by some amount.</span>
