Answer:
1 mole ozone gas
Explanation:
Since atomicity of Ozone (3) is maximum so, it will contain maximum number of atoms.
Best Answer: <span>(a)
8.9 x 10^-7 = x^2 / 0.15-x
x = [OH-] = 0.00037 M
pOH = 3.4
pH = 14 - 3.4 = 10.6
(b)
Ka = Kw/Kb = 5.6 x 10^-10 = x^2 / 0.20-x
x = [H+] = 0.000011 M
pH = 5.0</span>
<u>Answer:</u> This element has +2 charge on it.
<u>Explanation:</u>
An ion is formed when an atom looses or gains electrons.
- When an atom looses electrons, it leads to the formation of positive ion known as cation.
- When an atom gains electrons, it leads to the formation of negative ion known as anion.
Magnesium is the 12th element of the periodic table having electronic configuration of 
This element will loose 2 electrons to attain stable electronic configuration and leads to the formation of a cation having formula 
Hence, this element has +2 charge on it.
