Calcium sulfide quoted in wrong state? edit
The delta-G value for CaSO4 (s) should be 10 kJ/mol higher. I have 2 sources which state it as -1321.8 and -1321.1 kJ/mol resp. Also, calculating a reconstruction from delta-H and S yields 1322.1 for me. It seems the value presented here was just erroneously taken from (aq) state, which I have as -1310.3.

Value for Magnesium Oxide edit
The table in the article gives ΔGf of MgO is as -596.3 kJ/mol. However, calculating ΔGf of MgO (s) at 298.15 K from NIST data gives a value of -569.3 kJ/mol. It seems that the '6' and the '9' were wrongly exchanged in the table in the article. — Preceding unsigned comment added by 93.115.91.212 (talk) 07:33, 7 February 2019 (UTC)
