  13. 13. Rochel the end, Re-lyn dating At and Aries were got for about two years. They married to Neil, her really Jomar, became so father, love each other. happy. During the marriage Jomar saw One day while Aries and Rochel, were that time Aries Rochel at walking, they both her old time crush Resaw feel Cupid’s arrow in their heart.lyn. A few days later the two become sweethearts. Aries Aries stays as a Sadly, broke up with Rochel to have Re-lyn, but bachelor forever. Relyn’s father Jomar wants her to be with Neil.
  14. 14. Chemical Reaction
  15. 15. Introduction Chemical changes are called Chemical Reaction. In science, we write the Chemical Reaction in a form of Chemical Equation.
  16. 16. 2H2 + O2 2H2O Reactants Product
  17. 17. Types Of Chemical Reaction
  18. 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. 19. Combination Reaction A+B AB
  20. 20. Combination Reaction Example: C + O2 CO2
  21. 21. Decomposition Reaction Is the reverse of combination reaction. In this reaction, a complex substance is broken down into simpler substances.
  22. 22. Decomposition Reaction AB A+B
  23. 23. Decomposition Reaction Example: 2HgO 2Hg+O2
  24. 24. Single-Displacement Reaction Are reactions in which an element displaces another element that is in a compound. It is also known as Substitution Reaction.
  25. 25. Single-Displacement Reaction A+BC AC+ B NOTE!!!
  26. 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. 27. Single-displacement Reaction Example: Zn + 2HCl ZnCl2 + H2
  28. 28. Double-Displacement Reaction Are reactions in which two compounds make an exchange.
  29. 29. Double-Displacement Reaction AB+CD AD+CB
  30. 30. Double-displacement Reaction Example: BaCl2+ Na2SO4 BaSO4 + 2NaCl
