Answer :
Formal charge on C: (-1)
Formal charge on N: (0)
Net charge: (-1)
Explanation :
First we have to determine the Lewis-dot structure of
.
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 carbon has '4' valence electrons and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in
= 4 + 5 + 1= 10
According to Lewis-dot structure, there are 6 number of bonding electrons and 4 number of non-bonding electrons.
Now we have to determine the formal charge for each atom.
Formula for formal charge :



Net charge = -1 + 0 = -1
Carbon-12 and Carbon-14 are isotopes of Carbon. Although they have the same number of protons, the <span>number of neutrons in each atom is not the same~</span>
A spring tide is a tide at the shore just after a new or full moon, when there is the greatest difference between high and low water.
Answer:
Concentration of Ca(OH)₂:
0.117 M.
Explanation:
How many moles of HCl is consumed?
Note the unit of concentration: moles per liter solution.
.
Convert milliliters to liters.
.
.
How many moles of NaOH in the solution?
Refer to the equation. The coefficient in front of Ca(OH)₂ is 1. The coefficient in front of HCl is 2. In other words, it takes two moles of HCl to neutralize one mole of Ca(OH)₂. That
of HCl will neutralize only half that much Ca(OH)₂.
.
What's the concentration of the Ca(OH)₂ solution?
Concentration is the number of moles of solute per unit volume.
