This is an endothermic chemical reaction.
What is delta h in the equation delta g delta h - t delta s?
The change in enthalpy between products and reactants in a reaction
How is delta hf related to the delta h of the reaction?
^Hreaction = ^Hf, products - ^Hf, reactants Apex

What does the delta h of a reaction represent?
Either the change (which the delta refers to) of the height (which the h represents).
When a chemical reaction has a negative delta G is the reaction exothermic or endothermic?
When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative. Hope this helps :)
Delta H equals delta E plus delta nRT prove?
Yes
What is S in the equation delta G equals delta H minus TdeltaS?
The change in enthalpy between products and reactants in a reaction
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
