Presentation Transcript

  1. ExothermicReactions • Exothermic reactions release energy • They are hot and may steam Formula of reaction: 2 Al(s ) + 3 Br2(l ) --> 2 AlBr3(s ) (Aluminum and liquid Bromine) By Aiyana

  2. Endothermic Reaction • Endothermic reaction absorb energy • They feel very cold Formula for reaction: H2O + Ammonium Nitrate  H2OAN (Water and ammonium Nitrate)

  3. Synthesis • In a synthesis reaction two or more chemicals bond together forming one new substance. • Generic formula: A + B  AB Formula for reaction: 2K(s) + Cl2(g) 2KCl(s) (This is potassium chloride and chlorine gas)

  4. Decomposition • In a decomposition reaction one substance breaks down into two or more separate substances • Generic Formula: AB  A + B Formula of Reaction: 2 HgO  2 Hg + O2 (Oxygen and Mercury)

  5. Single Replacement • In a single replacement reaction one element knocks another element out of a compound. • Generic Formula: AB + X  AX + B Formula of Reaction: Zn + 2HCl  H2 + ZnCl2 (Zinc and Hydrochloric acid)

  6. Double Replacement • In a double replacement the two compounds switch ions with each other • Generic formula: AB + XY  AX + BY Formula for reaction: 2KI(aq) + Pb(NO3)2(aq)  2KNO3(aq) +PbI(s) (Potassium iodine and lead and nitrogen oxygen)

  7. Combustion • A combustion reaction is when a compound burns in oxygen gas • Oxygen will always be a reactant • Generic formula: A + O2 Formula for reaction: CH4 + 202 -> CO2 + 2H2O (Carbon hydrogen and oxygen)
