Explanation: Sodium is a metal with a low electronegativity it will form an ionic bond with a non metal with a high electronegativity.
Both Florine and Sulfur are non metals with high electronegativity.
Neon is a noble gas family VIII A and normally doesn't form any bonds at all.

Since the substance absorbs heat, it is expected that the temperature will rise. The formula for the internal energy of a substance is given by the equation:
ΔU = mCpΔT
where:
ΔU = internal energy
m = mass of substance
Cp = specific heat capacity of substance
ΔT = change in temperature
ΔU = 2722 Joules = 16.2 grams (9.22 J/g-°C) (Tf - 26°C)
This gives a final temperature of Tf = 44.22 °C
