How do you know if a reaction is entropy driven enthalpy driven or driven by both enthalpy and energy?
If the ∆H is positive and the ∆S is positive, then the reaction is entropy driven. If the ∆H is negative and the ∆S is negative, then the reaction is enthalpy driven. If ∆H is positive and ∆S is negative, then the reaction is driven by neither of these. If ∆H is negative and ∆S is positive, then the reaction is driven by both of these.
Can water decompose?
Yes water or H20 can decompose into H2 and O2 molecules. When driven by an electric current this process is called electrolysis. When driven by very high temperatures this process is called thermolysis.
How do water molecules move?
On the molecular level, water molecules move more or less randomly, driven mostly by entropy. On the cellular level, water follows solute concentration. This is the basis of osmosis and diffusion.
What makes chemical reaction spontaneous?
Stability of the products as compare to stability of reactants.
Why do hydrates change in color when water of crystallization is driven off?
In transition metal complexes water as ligands form the coordinate covalent bods and is responsible to split the d-orbitals in to two groups in which transition of electrons produces colour when water is driven off the splitting of d-orbitals becomes vanished and colour disappear.

What is driven by kinetic energy of the molecules?
'kinetic energy of molecules' is heat; so your answer is any heat engine: for example, a steam locomotive.
Which process is most directly driven by light energy?
removal of electrons from chlorophyll molecules removal of electrons from chlorophyll molecules
What has to be strong in order to cause a chemical reaction to take place?
Chemical reactions are driven by the amount of energy used to break the bonds in the reactants ( the activation energy) and the energy released by making new bonds in the products. The stronger the forces holding together the molecules of products, the more readily the reaction takes place. The difference between the energy produced in making the bonds and breaking the bonds is called ENTHALPY. The reaction can also be driven if the products have a greater degree of disorder (ENTROPY) than the reactants.
Buring paper is anabolic or catabolic endergonic or exergonic spontaneous or non-spontaneous?
Catabolic: long cellulose polymers are broken down into carbon dioxide, water, and carbon monoxide gases. Exergonic: can be used to do work Spontaneous: once started the reaction will reach completion by itself, driven by a very positive change in entropy. However the reaction has a high activation energy. Therefore it is thermodynamically favourable but kinetically unfavourable.

What is the source of oxygen gas released by a photo system?
The oxygen produced in photosynthesis is derived from the carbon dioxide the organism combines with water. The chemical reaction is driven by energy derived from light. The products of the reaction are oxygen and sugar, and the reaction isn't too difficult to understand. It looks like this:6CO2 + 6H2O → C6H12O6 + 6O2The carbon dioxide and water will, driven by the energy of light, chemically react to form sugar and oxygen.
What process is illustrated by the arrows labeled a in figure6-1?
The process illustrated by the arrows labeled "a" is diffusion. This is the movement of molecules from an area of higher concentration to an area of lower concentration, driven by the natural tendency of molecules to spread out and reach equilibrium.
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
