Answer :
The number of bonding pairs of electrons around the hydrogen atom = 2
The number of lone pairs of electrons around the hydrogen atom = 0
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 carbon has '4' valence electrons, hydrogen has '1' valence electrons and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in = 1 + 4 + 5 = 10
According to Lewis-dot structure we conclude that, there are 8 number of bonding electrons and 2 number of non-bonding electrons.
The number of bonding pairs of electrons around the hydrogen atom = 2
The number of lone pairs of electrons around the hydrogen atom = 0

Answer:
1. CaCO3(s) <=> CaO(s) +CO2 (g) Delta H = +178 kJ/mol
Since Delta H is positive, it means the reaction is endothermic
a. An increase in temperature will will shift the equilibrium position to the right, thus forming more products
b. A decrease in the temperature will shift the equilibrium position to the left, thus forming more reactants
2. PCl3(g) + Cl2(g) <-> PCl5 (g) Delta H= -88 kJ/mol
From the above, Delta H is negative which implies exothermic reaction.
c. Increasing the temperature will shift the equilibrium position to the left, thus forming more reactants.
d. Decreasing the temperature will shift the equilibrium position to the right, thus forming more products

<h2>
Answer:</h2>
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
<h2>
Explanation:</h2>
Chemical bonds are formed by gaining, yielding or sharing electrons to reach stable electronic configurations such as those of noble gases. Electropositive atoms give up electrons to complete the most stable configuration, leaving them with a negative charge defect.
