Bellow you my find the chemical equations of the ionization of a triprotic acid.
Explanation:
The chemical equations for the ionization of phosphoric acid (H₃PO₄), which is a triprotic acid, in water:
H₃PO₄ (s) + H₂O (l) → H₂PO₄⁻ (aq) + H₃O⁺ (aq)
H₂PO₄⁻ (aq) + H₂O (l) → HPO₄²⁻ (aq) + H₃O⁺ (aq)
HPO₄²⁻ (aq) + H₂O (l) → PO₄³⁻ (aq) + H₃O⁺ (aq)
where:
(s) - solid
(l) - liquid
(aq) - aqueous

Answer:
Mg(s) +<em> 2</em> HCl (aq) → H₂(g) + MgCl₂
0.415g of H₂(g) <em>-Assuming mass of Mg(s) = 10.0g-</em>
Explanation:
Balancing the reaction:
Mg(s) + HCl (aq) → H₂(g) + MgCl₂
There are in products two atoms of H and Cl, the balancing equation is:
Mg(s) +<em> 2</em> HCl (aq) → H₂(g) + MgCl₂
<em>Assuming you add 10g of Mg(s) -Limiting reactant-</em>
<em />
10g of Mg are (Atomic mass: 24.305g/mol):
10g × (1 mol / 24.305g) = <em>0.411 moles of Mg</em>
<em>-Theoretical yield is the amount of product you would have after a chemical reaction occurs completely-</em>
Assuming theoretical yield, as 1 mole of Mg(s) produce 1 mole of H₂(g), theoretical yield of H₂(g) is 0.411moles H₂(g). In grams:
0.411mol H₂(g) × (1.01g / mol) = <em>0.415g of H₂(g)</em>
Answer:
a. True
Explanation:
Distillation process is a process that is used to separate the components or the substances from the liquid mixtures by using selectively boiling and condensation.
While fractional precipitation is a process which separates the ions from solution based on the different solubilities.
Therefore, the answer is true.
If you add a potassium nitrate and saturated solution you will make a super-saturated solution of potassium nitrate. But what to expect with this process of adding these 2. It is that the result of this solution made/forms bigger crystals that have pointed ends. If there is no appearance of the crystal it shows that the solution is not yet cooled.
