What is Gibbs Free energy
The usable energy released or absorbed by a reaction.
How many triangles in star of David
If it is in the form of two inverted triangles, then there are 8
triangles.
If only the outline is used, there are 0 triangles.
How does a substance change when its thermal energy changes
For example, when heat energy (thermal energy) is added to a
substance, either its temperature will increase, or it will change
its state (as when ice is melted).
How is the Hfusion used to calculate volume of liquid frozen that produces 1 kJ of energy
1kJ 1/Hfusion g/mol ml/g liquid
What happens when a glass of water is set in the sun until the water evaporates
What factors generally determine whether a reaction happens or not
What is the value for G at 300 K if H 27 kJmol and S 0.09 kJmolK
What is the name of the field of study with laws that describe how energy is transferred to different locations and forms
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants
The difference between the enthalpy of formation of the products
minus the enthalpy of formation of the reactants is the enthalpy of
the reaction
