Explanation:
Sublimation is the phase transition of a substance directly from the solid to the gaseous phase without passing through the liquid phase.
Here are the three forces that exist between two NH3 molecules:
1- Dispersion forces - these forces exist between ANY two molecules, regardless of anything else.
2- Dipole-dipole interactions - NH3 is a polar molecule with a permanent separation of charge. Each molecule behaves like a tiny magnet and has + and - poles so 2 NH3 molecules attract each other. Dipole-dipole interactions are stronger than dispersion forces in small molecules.
3- Hydrogen bonding - H is directly bonded to the extremely electro negative atoms N, O, or F, hence hydrogen atom is nearly stripped off electrons due to the large electro - negativity difference. Hydrogen being a small atom further reduces in size even allowing it to approach other molecules very closely. Here N,O,F gathers more partial negative charge.
Due to the close approach between the molecules and the strong partial charges, hydrogen bonding is generally more important than dipole-dipole interactions.
So the main intermolecular force must be hydrogen bonding.
The complete equation representing the synthesis reaction for the formation of ammonia is: 3 H₂ + N₂ ⇒ 2 NH₃
<h3>What is a synthesis reaction?</h3>
It is a reaction in which 2 or more substances combine to form 1 product.
Let's consider the following incomplete synthesis reaction.
3 H₂ + ____ ⇒ 2 NH₃
According to Lavoisier's law, the mass and the elements must be conserved in a chemical reaction. So, since there is nitrogen to the right, the missing element to the left must be nitrogen. Molecular nitrogen is diatomic.
The complete reaction is:
3 H₂ + N₂ ⇒ 2 NH₃

They tend to pick at it until it is in small enough pieces to swallow. Then their gizzard (rough muscle) in their stomach acts as internal teeth.
