Slide1
Exothermic vs Endothermic … 29
Reactants - the chemicals you start a reaction with Products- the chemicals that end the reaction
Reactants
Al + Fe
2
O3 Al2O3 + 2 Fe
productsSlide2
Exothermic and Endothermic…29Slide3
Endothermic
A reaction that absorbs energy
Decrease in temperature (cold)
Reactants + Energy = products
First aid cold packs
Photosynthesis (uses sun’s energy)CO2 + H20 + energy C6H12O6 + O2Slide4
Exothermic
A reaction that releases energy
Increase in temperature (heat)
Reactants = products + energy
Ex. Jellyfish, fireflies
Cellular Respiration (makes energy for you)Lights upC6H12O6 + O2 CO2 + H20 + energy
