jfraser · Answer

you need a table of standard entropy values, do you have one?

anonymous · Answer

Substance	Sº(J/mol*K)
Al2O3(s)	51
H2(g)	131
Al(s)	28
H2O(g)	189

@JFraser is that what it is?

jfraser · Answer

that's probably it

jfraser · Answer

the formula for finding $\Delta S$ is:
$$\Delta S_{rxn} = \Sigma n(\Delta S_{products}) - \Sigma m(\Delta S_{reactants})$$where $n$ and $m$ are the coefficients of each reactant and product as it appears in this balanced equation

Can you walk me through it step by step? I'm not good with Chemistry at all.
