the potential energy of the molecules changes during a reaction.
I think what you are looking for is a catalyst. A catalyst lowers the energy or activation for a reaction, allowing it to happen faster. During the reaction nothing actually happens to or changes the catalyst.
As the temperature is lowered, the movement of the molecules decreases.
the negative value for a standard potential indicates that the reaction is not spontaneous.
Antigens are surface membrane molecules that cause an immune reaction.
An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.

Yes, molecules have potential energy stored in their chemical bonds.
That happens all the time. Smaller molecules combine to form larger molecules; larger molecules break up into smaller molecules.
When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.
A chemical reaction between oxygen and hydrogen occur.
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
a chemical reaction in which simple molecules are added to each other to form long chain molecules without by products
Chemical energy is potential energy until the chemical reaction puts atoms and molecules in motion. Heat energy (KE) is often the result of a chemical reaction.
When sodium iodide is exposed to light, it may undergo a photochemical reaction where it can decompose or form other products. This is because the light energy can excite the molecules in sodium iodide, leading to potential photoreactions.
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
