Answer:
7.4.
Explanation:
∵ pH = -log[H₃O⁺].
∴ pH = -log(2.5 x 10⁻⁷) = 6.6.
<em>∵ pH + pOH = 14.</em>
<em />
∴ pOH = 14.0 - pH = 14.0 - 6.6 = 7.4.
Balanced chemical reaction: 2HI(aq) + Ba(OH)₂(aq) → BaI₂(aq) + 2H₂O(l).
Ionic reaction: 2H⁺ + I⁻(aq) + Ba²⁺ + 2OH⁻(aq) → Ba²⁺ + 2I⁻(aq) + 2H₂O(l).
Net ionic reaction: 2H⁺ + 2OH⁻(aq) → 2H₂O(l).
Barium iodide is salt that dissolves in water, barium hydroxide is strong base that dissolves in water.
This is example of double replacement reactions(double displacement or metathesis reactions), two ionic compounds are exchanged, making two new compounds
.
Because hidrogen ions in acid and hidroxide ions in base reacts to form H²O. Heat are produced in order the electrons to bond
Answer:
Biotic components, or biotic factors, can be described as any living component that affects another organism or shapes the ecosystem. This includes both animals that consume other organisms within their ecosystem, and the organism that is being consumed
