Answer : The Lewis structure of is shown below.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that nitrogen has '5' valence electrons, oxygen has '6' valence electrons and hydrogen has '1' valence electron.
Therefore, the total number of valence electrons in = 5 + 3(1) + 6 = 14
According to Lewis-dot structure, there are 8 number of bonding electrons and 6 number of non-bonding electrons.
The Lewis-dot structure of is shown below.
Answer:
80ml
Explanation:
you have your initial concentration to be 0.25 mole on your final volume to be 250 ml and your final concentration to be 0.8 0.08 molar you don't have your initial volume sotify your initial volume you use the expression see 1 * 21 equals see two times between you make when when the subject then 1 equals to 2 x 2/3 one you know substitute your values into it to get being one that's your original volume to be at the latest or 80 ml
