Aluminum oxide melts at 2300 oK, and the heat of fusion is 26 kcal/mole. Assuming that the internal energy and the entropy changes that take place in going from the solid to the liquid state are independent of temperature, calculate the free energy that would be released if molten Al2O3 were to freeze at 1800 oC (e. g., because of undercooling)

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

Read the chemical equation. 2c2h2 + 5o2 → 4co2 + 2h2o which of the following statements would be correct if one mole of c2h2 was used in this reaction? one mole of oxygen was used in this reaction. five moles of oxygen were used in this reaction. four moles of carbon dioxide were produced from this reaction. two moles of carbon dioxide were produced from this reaction.
