  1. Chemical Reactions By Matt Reeder

  2. What is a chemical reaction? A chemical reaction is a reaction between two atoms forming a chemical bond resulting in a chemical compound.

  3. Why do chemical reactions happen?

  4. What is a chemical equation? A chemical equation is a way of writing out and describing a chemical reaction.

  5. Why are chemical equations used? Chemical equations are used to simplify and express the specific reactants and product of a chemical reaction.

  6. Should chemical equations be balanced? YES! The law of conservation of matter states that matter cannot be created or destroyed. All elements that are a part of the left side of the equation must appear, in some form, on the left side of the equation.

  7. Parts of a chemical equation

  8. Reactants vs. Products

  9. For example…

  10. For example…

  11. The arrow in a chemical equation The arrow in a chemical equation represents the action, or reaction taking place forming the chemical bond. 2H2 + O2 H2O

  12. SYNTHESIS REACTION • A type of reaction where two or more atoms join to form a more complex compound. • Reactant + reactant product • 2H2+02H2O

  13. Peanut butter + Chocolate Reeses

  14. DECOMPOSITION REACTION • Opposite of a Synthesis reaction. • One reactant compound separates resulting in two or more products. • Reactant Product + Product • 2H2O2 2H2 + O2

  15. Firecracker = Explosion + cardboard

  16. SINGLE REPLACEMENT REACTION • A reaction involving more than two elements in which one element takes the place of another one. • Reactant + reactant product + product • Zn + 2HCl ZnCl2 + H2

  17. Baby and toy + big brother = baby + big brother and toy

  18. Double Displacement • Two compounds react to form two new compounds. • reactant + reactant Product + product • AgNO3 + NaClAgCl + NaNO3

  19. John(Ferrari) + Kaleb(Subaru) = John(Subaru) + Kaleb(Ferrari)

  20. The End
