The Lewis structure of the hydrogen cyanide molecule is represented by the image shown.
<h3>
What is the Lewis structure?</h3>
We know that the Lewis structure is showing us the relationship between the electrons pairs in the compound and its overall properties. The Lewis structure consists of the symbol of the element and the electrons pairs that surround the atom.
We can see that in hydrogen cyanide there is a nitrogen atom and there is a hydrogn atom and also one carbon atom. The bond between carbon and nitrogen is covalent while the bond between hydrogen and the cyanide moiety is covalent.

Answer:
Option C. 251 kJ
Explanation:
The activation energy (Ea) of a given reaction is the minimum energy that must be overcomed for reactant to proceed to product.
The activation energy (Ea) can be obtained from an energy profile diagram by simply calculating the difference between the energy of the activation complex (i.e the peak) and the energy of the reactant.
Thus, we can obtain the activation energy for the reaction above as follow:
Activation complex = 332.6 kJ
Energy of reactant = 81.6 kJ
Activation energy =?
Activation energy = Activation complex – Energy of reactant
Activation energy = 332.6 – 81.6
Activation energy = 251 kJ
Therefore, the activation energy of the reaction is 251 kJ
<h2><u>
Calcium Carbonate</u>
. Calcium carbonate is another example of a compound with both ionic and covalent bonds. Here calcium acts as the cation, with the carbonate species as the anion. These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded.</h2><h2 />
