Answer:
Option (d) is correct
N³⁻ > F⁻ > Mg²⁺ > Si⁴⁺
Explanation:
Total electrons for all the species = 10
So these are <u>iso electronic</u> with each other.
We know
Ionic radii ∝
- Si⁴⁺ has 14 protons and 10 electrons
- Mg²⁺ has 12 protons and 10 electrons
- N³⁻ has 7 protons and 10 electrons
- F⁻ has 9 protons and 10 electrons
- Iso electronic species with greatest number of protons have small size and vice versa.
- So Si⁺⁴ have smallest size and N³⁻ have largest in size
Answer:
Explanation:
From the information given:
no of moles of = 0.01 L × 0.0010 mol/L
no of moles of =
no of moles of = 0.01 L × 0.00010 mol/L
no of moles of =
Total volume = 0.02 L
Since Q<ksp, then there will no be any precipitation of CaF2
