Presentation Transcript

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
