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
<h3><u>Answer;</u></h3>
Coefficient
<h3><u>Explanation;</u></h3>
- Coefficients are the numbers in front of the chemical formulas.
- For example in 3H2O ,the three infront of the water molecule is called the coefficient.
- These numbers give two very important pieces of information about a chemical equation. The coefficients give the number of molecules (or atoms) involved in the reaction.
- Additionally, coefficient give the number of moles of each substance involved in the reaction.
So the molarity equation is moles of solute/liters of solution. so i’m pretty sure the answer should be 0.63/0.70= .9
