In the Gibbs energy equation is "s" the symbol for entropy?

No.

$s$ $s$ is not the symbol for entropy. Sometimes, $s$ $s$ is used for specific heat capacity in $J/g \cdot K$ $"J/g"cdot"K"$ :

$q = msDeltaT$

where:

$q$ is heat flow in $"J"$ . In is positive, and out is negative.

$m$ is mass in $"g"$ .

$DeltaT$ is change in temperature in $"K"$ or $""^@ "C"$ .

Entropy, however, is featured as $ul(ul(S))$ :

$\mathbf(DeltaG = DeltaH - TDeltaS)$

where:

$DeltaG$ is the Gibbs' Free Energy in $"kJ/mol"$ .

$DeltaH$ is the enthalpy in $"kJ/mol"$ .

$T$ is the temperature in $"K"$ .

$DeltaS$ is the entropy in $"J/K"cdot"mol"$ .

The capitalization matters.
