Answer:
Twice as much.
Explanation:
That's because the freezing point depression depends on the total number of solute particles.
C₆H₁₂O₆(s) ⟶ C₆H₁₂O₆(aq)
0.01 mol of C₆H₁₂O₆ gives 0.01 mol of solute particles.
NaCl(s) ⟶ Na⁺(aq) + Cl⁻(aq)
1 mol of NaCl gives 0.01 mol of Na⁺(aq) and 0.01 mol of Cl⁻(aq).
That's 0.02 mol of particles, so the freezing point depression of 0.01 mol·L⁻¹ NaCl will be twice that of 0.01 mol·L⁻¹ C₆H₁₂O₆.
Answer:
First ionization step:
H₂SeO₄(aq) + H₂O(l) → H₃O⁺(aq) + HSeO₄⁻(aq)
Second ionization step:
HSeO₄⁻(aq) + H₂O(l) → H₃O⁺(aq) + SeO₄⁻²(aq)
Explanation:
Selenic acid is a dyprotic and a strong acid with the formula: H₂SeO₄.
When it reacts to water, it release two protons in two ionizations.
Finally it gives hydronium to the medium.
H₂SeO₄(aq) + H₂O(l) → H₃O⁺(aq) + HSeO₄⁻(aq)
HSeO₄⁻(aq) + H₂O(l) → H₃O⁺(aq) + SeO₄⁻²(aq)
The flow of energy starts with the sun. Like plants can make their energy through the sunlight from the sun. And they create food from the process of photosynthesis.
