Explanation:
The lewis dot structure or electron dot structure is a notation that shows only the chemical symbol of the element surrounded by dots to represent the valence electrons.
- The chemical symbol represents the nucleus and all electrons except the valence electrons.
- The dots are arranged at the four sides of the symbol pairs called lone pairs.
- Those that are unpaired are called odd electrons.

Answer:
(ΔHrxn) = 1.273kJ/mol
Explanation:
Applying
m=78.2, c= 3.97, ∆t= 25.8-21.7
(ΔHrxn)= mc∆t
=78.2× 3.97× 4.1= 1.273kJ/mol
