Answer:
4.5 × 10⁻⁹
Explanation:
Step 1: Write the reaction for the solution of CaCO₃
CaCO₃(s) ⇄ Ca²⁺(aq) + CO₃²⁻(aq)
Step 2: Convert the solubility of CaCO₃ from g/L to mol/L
We will use the following conversion factors:
- The molar mass of CaCO₃ is 100.09 g/mol.
- 1 L= 1000 mL.
- There are 0.00067 g of CaCO₃ per 100 mL of solution.
Step 3: Calculate the solubility product constant (Ksp)
To relate Ksp and the molar solubility (S), we need to make an ICE chart.
CaCO₃(s) ⇄ Ca²⁺(aq) + CO₃²⁻(aq)
I 0 0
C +S +S
E S S
The solubility product constant is:
Ksp = [Ca²⁺].[CO₃²⁻] = S² = (6.7 × 10⁻⁵)² = 4.5 × 10⁻⁹
Answer:
atom are very tiny partical
The answer would be true
Physical properties are characteristic that was not related to the chemical property such as color, density or boiling point. It should be same if the substance is the same. the difference in mass won't change it.
Mass and volume is the example of extensive property, so <span>10 gram of iron will have different extensive property than 20 gram of iron.</span>
