Chemical reactions

• Complete combustion there is a good supply of oxygen
• Incomplete combustion there is a limited supply of oxygen
• Complete Combustion- fuel (unknown) + oxygen ----> Carbon Dioxide + water
• Incomplete Combustion- fuel (unknown) + oxygen ----> Carbon monoxide + water
• Thermal decompostion- Breaking down a reactant using heat
• During a chemical reaction atoms are never created or destroyed they are rearranged
• In a chemical reactions the left side of the arrow is a reactant
• In a chemical reaction the arrow represents reacts to form
• In a chemical reaction on the right side of the arrow is the products
• Exothermic- reaction that releases energy into the surrounding so the temperature of the surrounding will increase
• Endothermic- Reactions that absorb energy out of the surroundings. So the temperature of the surroundings will decrease
• Respiration- exothermic
• Thermal decompostion- endothermic
