Answer:
1s2 2s2 2p6
Explanation:
ththe noble gas config. of neon
Given :
Molarity of sulfuric acid solution is 3.0 M.
Amount of sulfuric acid present in solution is 9.809 g.
To Find :
The volume of solution.
Solution :
We know, molarity is given by :

Therefore, volume required is 33.33 ml .
CaO because oxygen have 2 dots and calcium as well
(oxygen valency -2
calcium valncy +2)= CaO
It's quite strong and has a weak base . it would probably dissolve and the ph would drop
-NH2 is the most favorable for the reaction
