Explanation-
Water is a compound because it is formed from hydrogen and oxygen, which is irreversible, having different properties but air is a combination of different gases in any proportion.
My answer will be B and D
Answer:
Explanation:
Molar mass of FeCl3 = 162.2 g/mol
1 mole FeCl3 -------------- 162.2 g
mole FeCl3 ---------------- 1.1 g
moles = 1.1 / 162.2
= 0.00678 moles
The trend for the radii is Mg²⁺ < Na+ < Ne <F⁻
<h3>What does Ionic size varies with number of protons ?</h3>
With the increase in number of protons in the nucleus the electrons are more attracted towards nucleus and so the ionic radius decreases.
Ionic size increases with the addition of electrons and ionic size decreases with the loss of electrons.
Higher is the atomic number, higher will be the effective nuclear charge, lower will be the size.
F⁻
no. of proton=9
no of electron = 10
Na+
no. of proton=11
no of electron=10
Mg²⁺
no. of proton=12
no of electron=10
Ne
no. of proton=10
no of electron=10
Mg²⁺ < Na+ < Ne <F⁻
Therefore the trend for the radii is Mg²⁺ < Na+ < Ne <F⁻
