  1. Balance These Equations • Fe + H2S04 Fe2(SO4)3 + H2 • SnO2 + H2 Sn + H2O • KNO3 + H2CO3 K2CO3 + HNO3

  2. Exothermic and Endothermic Reactions LO: Define the terms exothermic and endothermic. State that in a reaction bonds have to be broken and then made.

  3. Are fireworks an exothermic or endothermic reaction?

  4. Exothermic Reactions • A reaction where energy is given out from the reaction into the surroundings. A temperature rise would be measured.

  5. Endothermic Reaction • A reaction where energy is taken into the reaction from the surroundings. A temperature drop would be measured. Hot and Cold Packs

  6. Lab

  7. Say if each example is an exothermic or endothermic reaction. • Using an ice pack on an injury. • Burning a match. • Respiration. • Dynamite exploding. • An ice cube melting. • Glow sticks glowing. • The reaction of an acid and a metal. • Photosynthesis.

  8. Endothermic • Exothermic • Exothermic • Exothermic • Endothermic • Exothermic • Exothermic • Endothermic
