  1. 4. reaction ( any chemical reaction that absorbs heat from its environment.)
  2. 7. (a mark or character used as a conventional representation of an object, function, or process, e.g. the letter or letters standing for a chemical element or a character in musical notation.)
  3. 8. (the basic unit of a chemical element.)
  4. 10. (a thing that inhibits someone or something.)
  5. 11. reaction (a chemical reaction that releases energy by light or heat.)
  6. 13. (the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and how they interact, combine, and change; and the use of these processes to form new substances.)
  7. 14. Change (a type of change where the physical properties of matter change.)
  8. 16. (a substance made by mixing other substances.)
  9. 18. (a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.)
  10. 21. (cause (an event or situation, typically one that is bad or undesirable) to happen suddenly, unexpectedly, or prematurely.)
  11. 23. (a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component. The solvent)
  12. 24. (a numerical or constant quantity placed before and multiplied the variable in an algebraic)
  13. 25. equation (a symbolic representation of a chemical reaction in the form of symbols and formulae.)
  14. 28. (the state or process of rotting; decay.)
Down
  1. 1. (the combination of ideas to form a theory or system.)
  2. 2. (an article or substance that is manufactured or refined for sale.)
  3. 3. (a substance that takes part in and undergoes change during a reaction.)
  4. 5. (a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.)
  5. 6. (a thing that is composed of two or more separate elements; a mixture.)
  6. 9. of mass (a principle stating that mass cannot be created or destroyed.)
  7. 12. (the action or process of replacing someone or something.)
  8. 13. (the process of burning something.)
  9. 15. bond (a connection between two surfaces or objects that have been joined together, especially using an adhesive substance, heat, or pressure.)
  10. 17. (a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction.)
  11. 19. formula (a mathematical relationship or rule expressed in symbols.)
  12. 20. (of a letter, figure, or symbol) written or printed below the line.)
  13. 22. (material such as coal, gas, or oil that is burned to produce heat or power.)
  14. 25. Change (a change of materials into another, new materials with different properties and one or more than one new substance are formed.)
  15. 26. (a part or aspect of something abstract, especially one that is essential or characteristic.)
  16. 27. energy (the minimum quantity of energy that the reacting species must possess to undergo a specified reaction.)
