Explanation:
The balanced chemical equation for ionization of in water is:
According to stoichiometry :
1 mole of ionizes to give =2 mole of
ions
0.001 mole of ionizes to give =
mole of
ions
Thus of a solution of 0.001 M aqueous sulfuric acid is 0.002 M
Answer:
Explanation:
Chlorine has electronic configuration of 2 , 8 , 7
In n = 3 there are 7 electrons out of which 2 are in s , and 5 are in p . But out of 5 electrons in p , one electron jumps into d orbital . so the electronic configuration becomes as follows
= 7
These orbitals like sp³d hybridise to form 7 degenerate orbitals out of which 2 orbitals contain electrons in pairs and rest three are singly occupied by electrons.( unpaired electrons )
