The compound NCl5 is the compound that cannot exist since the atom of nitrogen can react only to at most 3 other atoms. The PCl5 can exist in nature as phosphorus may bound with this number of other atoms and is named, phosphorus pentochloride.
N-Pentane has a higher boiling point than the other three elements
||| < || < | < |V
n-Pentane and 2,2-Dimethylpropane are isomers of one another and have the same chemical formula. Only London dispersion forces (LDFs), the smallest intermolecular forces, exist between the two molecules. The connectedness of the carbon skeleton accounts for the variation in their boiling points. While 2,2-dimethylpropane is a branching hydrocarbon, n-pentane is a straight hydrocarbon. Because of the n-linear pentane's shape, which results in greater surface areas between molecules, there are more LDFs between the molecules. N-Pentane has a higher boiling point as a result.
- Because they have hydrogen bonds, 1-pentanol and (R)-4-hydroxypentanoic acid have higher boiling points than hydrocarbons. While (R)-4-hydroxypentanoic acid has both an alcohol group and an acid group, which can also hydrogen, 1-pentanol only has a single alcohol group.

Answer:
1) Lithium + chlorine → Lithium chloride
2) Li + Cl₂ → LiCl
Explanation:
Skeleton equation:
Li + Cl₂ → LiCl
Skeleton equation with physical states:
Li(s) + Cl₂(g) → LiCl(s)
Balanced equation:
2Li(s) + Cl₂(g) → 2LiCl(s)
Word equation:
Lithium + chlorine → Lithium chloride
When solid lithium react with gaseous chlorine it form lithium chloride. The oxidation state of lithium is +1 while that of chlorine is -1. Thus one atom of lithium and one atom of chlorine are combined to make overall compound neutral and both are in stable state.
c.diamonds are the hardest
