2. Thermochemical equation - Wikipedia

   en.wikipedia.org/wiki/Thermochemical_equation

   In thermochemistry, a thermochemical equation is a balanced chemical equation that represents the energy changes from a system to its surroundings. One such equation involves the enthalpy change, which is denoted with Δ H {\displaystyle \Delta H} In variable form, a thermochemical equation would appear similar to the following:

3. Thermochemistry - Wikipedia

   en.wikipedia.org/wiki/Thermochemistry

   Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling.A reaction may release or absorb energy, and a phase change may do the same.

4. Job plot - Wikipedia

   en.wikipedia.org/wiki/Job_plot

   Within chemistry, a Job plot, otherwise known as the method of continuous variation or Job's method, is a method used in analytical chemistry to determine the stoichiometry of a binding event. The method is named after Paul Job and is also used in instrumental analysis and advanced chemical equilibrium texts and research articles.

5. Standard enthalpy of reaction - Wikipedia

   en.wikipedia.org/wiki/Standard_enthalpy_of_reaction

   Most values of standard thermochemical data are tabulated at either (25°C, 1 bar) or (25°C, 1 atm). [ 2 ] For ions in aqueous solution, the standard state is often chosen such that the aqueous H + ion at a concentration of exactly 1 mole/liter has a standard enthalpy of formation equal to zero, which makes possible the tabulation of standard ...

6. Ceria based thermochemical cycles - Wikipedia

   en.wikipedia.org/wiki/Cerium(IV)_oxide–cerium...

   A ceria based thermochemical cycle is a type of two-step thermochemical cycle that uses as oxygen carrier cerium oxides (/) for synthetic fuel production such as hydrogen or syngas. [1]

7. Thermometric titration - Wikipedia

   en.wikipedia.org/wiki/Thermometric_titration

   Titration plot of back-titration of excess EDTA with Cu(II) in NH 3 /NH 4 Cl buffered solution. A thermometric titration is one of a number of instrumental titration techniques where endpoints can be located accurately and precisely without a subjective interpretation on the part of the analyst as to their location.

8. Thermodynamic databases for pure substances - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_databases...

   Thermodynamic data is usually presented as a table or chart of function values for one mole of a substance (or in the case of the steam tables, one kg). A thermodynamic datafile is a set of equation parameters from which the numerical data values can be calculated.

9. List of unsolved problems in chemistry - Wikipedia

   Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
