Answer : The Lewis-dot 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, ![NH_3](https://tex.z-dn.net/?f=NH_3)
As we know that hydrogen has '1' valence electron and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in
= 5 + 3(1) = 8
According to Lewis-dot structure, there are 6 number of bonding electrons and 2 number of non-bonding electrons.
Now we have to determine the formal charge for each atom.
Formula for formal charge :
![\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%7D%3D%5Ctext%7BValence%20electrons%7D-%5Ctext%7BNon-bonding%20electrons%7D-%5Cfrac%7B%5Ctext%7BBonding%20electrons%7D%7D%7B2%7D)
![\text{Formal charge on N}=5-2-\frac{6}{2}=0](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%20on%20N%7D%3D5-2-%5Cfrac%7B6%7D%7B2%7D%3D0)
![\text{Formal charge on }H_1=1-0-\frac{2}{2}=0](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%20on%20%7DH_1%3D1-0-%5Cfrac%7B2%7D%7B2%7D%3D0)
![\text{Formal charge on }H_2=1-0-\frac{2}{2}=0](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%20on%20%7DH_2%3D1-0-%5Cfrac%7B2%7D%7B2%7D%3D0)
![\text{Formal charge on }H_3=1-0-\frac{2}{2}=0](https://tex.z-dn.net/?f=%5Ctext%7BFormal%20charge%20on%20%7DH_3%3D1-0-%5Cfrac%7B2%7D%7B2%7D%3D0)
Hence, the Lewis-dot structure of
is shown below.
Answer:
The strength of an acid or alkali depends on the degree of dissociation of the acid or alkali in water. The degree of dissociation measures the percentage of acid molecules that ionise when dissolved in water. He could use universal indicators or litmus paper for this.

Answer:
The molecular formula of glucose is C₆H₁₂O₆
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of smallest whole number of atoms.
Molecular formula:
It gives the total number of atoms in a molecule of compound.
The molecular formula and empirical formula can be related as follow:
Molecular formula = n × empirical formula
Given data:
Empirical formula = CH₂O
Molecular formula = ?
It is stated in given problem that molecular formula is the 6 times of the empirical formula.
Molecular formula = n × empirical formula
Molecular formula = 6 × CH₂O
Molecular formula = C₆H₁₂O₆
The molecular formula of glucose is C₆H₁₂O₆.
