<h3>What are decomposition reactions?</h3>
- Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
- When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
- When this happens the soluble compound such as ionic compounds ionizes to form ions.
- This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
- For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)
Answer:
11.76
Explanation:
Potassium hydroxide is a strong base that dissociates completely according to the following reaction.
KOH(aq) → K⁺ + OH⁻
Then, the concentration of OH⁻ will be 0.00580 M.
The pOH of the solution is:
pOH = -log [OH⁻]
pOH = -log 0.00580 = 2.24
We can calculate the pH using the following expression.
pH + pOH = 14
pH = 14 - pOH = 14 - 2.24 = 11.76
The answer is Eukaryotic cells.
