C. the number of protons and neutrons an element has in its nucleus
As mentioned above, phosphoric acid has 3 pKa values, and after 3 ionization it gives 3 types of ions at different pKa values:
H₃PO₄(aq)
+ H₂O(l) ⇌ H₃O⁺(aq) + H₂PO₄⁻ (aq) pKₐ₁
<span>
</span>H₂PO₄⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HPO₄²⁻ (aq) pKₐ₂
HPO₄²⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + PO₄³⁻ (aq) pKₐ₃
At the highest pKa value (12.4) of phosphoric acid, the last OH group will lose its hydrogen. On the picture I attached, it is shown required protonated form of phosphoric acid before reaction whose pKa value is 12.4.
Answer:
The answer to your question is: letter D
Explanation:
A. a motile archaea Archea don't have peroxisomes then this option is wrong.
B. a nonmotile eukaryote The new organism has flagella then it can move, so this option is wrong.
C. a motile bacterium Bacterium don't have peroxisomes so this option is wrong.
D. a motile eukaryote This is the correct option because an eukaryote can have all the characteristics described.
Answer:
The couch will not move because the people are not working together. Maybe if they call someone to help they can make some progress.
