Chemical Reaction 15. IntroductionChemical changes are called Chemical Reaction. In science, we write the Chemical Reaction in a form of Chemical Equation. 16. 2H2 + O22H2OReactantsProduct 17. Types Of Chemical Reaction 18. Combination Reaction Also known as synthesis reactions, these are reactions in which 2 or more substances combine to form a more complex substance. 19. Combination ReactionA+BAB 20. Combination ReactionExample:C + O2CO2 21. Decomposition ReactionIs the reverse of combination reaction. In this reaction, a complex substance is broken down into simpler substances. 22. Decomposition ReactionABA+B 23. Decomposition ReactionExample:2HgO 2Hg+O2 24. Single-Displacement ReactionAre reactions in which an element displaces another element that is in a compound. It is also known as Substitution Reaction. 25. Single-Displacement ReactionA+BCAC+ B NOTE!!! 26. Note!!! Refer to the activity series for metals and non metals to predict products of replacement reactions. If the free element is above the element to be replaced, then the reaction will occur. If it is below, then no reaction occurs. 27. Single-displacement ReactionExample:Zn + 2HCl ZnCl2 + H2 28. Double-Displacement ReactionAre reactions in which two compounds make an exchange. 29. Double-Displacement ReactionAB+CDAD+CB 30. Double-displacement ReactionExample:BaCl2+ Na2SO4BaSO4 + 2NaCl 31.
