4. AREA- The surface area is simply the area of all of the outside surfaces of a three-dimensional object.
5. CHEMICAL REATION- A reversible reaction is a reaction where the reactants form products react together to give the reactants back.
8. is any chemical reaction that involves the moving of electrons.
9. the exertion of force upon a surface by an object, fluid, etc.
10. the breakdown of a single entity into two or more fragments.
11. ENERGY- It is defined as the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.
13. a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.
14. ELECTRON- an electron of an atom, located in the outermost shell (valence shell) of the atom, that can be transferred to or shared with another atom.
15. is a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light.
19. REPLACEMENT REACTION- is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
22. is equal to the system's internal energy plus the product of its pressure and volume

1. a measure of the warmth or coldness of an object or substance with reference to some standard value
2. a solution that can resist pH change upon the addition of an acidic or basic components.
3. a substance that speeds up a chemical reaction
6. measure of the amount of dissolved substance contained per unit of volume.
7. a substance obtained from another substance through chemical change.
12. any substance that undergoes a chemical change in a given reaction.
16. is the artificial execution of useful chemical reactions to obtain one or several products.
17. is a substance that decreases the rate of, or prevents, a chemical reaction.
18. CHATELIER'S PRINCIPLE- the principle that if a system in chemical equilibrium is subjected to a disturbance it tends to change in a way that opposes this disturbance.
20. COMPLEX- is the structure that results in the maximum energy point along the reaction path.
21. The reaction rate or rate of reaction is the speed at which reactants are converted into products.
22. a function of thermodynamic variables, as temperature, pressure, or composition, that is a measure of the energy that is not available for work during a thermodynamic process.
