The net ionic equation of the reaction is:

  • Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)

<h3>What are net ionic equations?</h3>

Net ionic equations are equations where ions which remain in solution known as spectator ions are not shown in the equation. Only ions involved in formation of product are shown.

In the given equation, sodium and nitrate ions are spectator ions.

The net ionic equation of the given reaction is as follows:

  • Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)

In conclusion, spectator ions are not shown in net ionic equation.

Which forces are intramolecular and which intermolecular?
AleksAgata [21]

Butter won't melt in a fridge because of intermolecular tensions. While the bonds inside of the fat molecules are unbroken, the attractions between the fat molecules are weaker.

What intermolecular forces are present in butter?

The intermolecular forces known as London dispersion forces are the weakest and are most prominent in hydrocarbons. Due to the fact that butter molecules are hydrocarbons, London dispersion forces do exist between them.

How do intermolecular forces affect melting?

More energy is required to stop the attraction between these molecules as the intermolecular forces become more powerful. Because of this, rising intermolecular forces are accompanied with rising melting points.

Which forces are intramolecular and which are intermolecular?

Intramolecular forces are those that hold atoms together within molecules. The forces that hold molecules together are known as intermolecular forces.
