Reactions Flashcards
1
Q
what is an endothermic reaction
A
endothermic absorbs energy (photosynthesis, melting ice)
2
Q
what is an exothermic reaction
A
exothermic releases energy in heat (fireworks, respiration)
3
Q
complete combustion
A
complete combustion is when there is enough oxygen to produce carbon dioxide
4
Q
incomplete combustion
A
when there is a lack of oxygen which releases carbon monoxide
5
Q
general equation for the combustion of methane
A
methane + oxygen → carbon dioxide + water
6
Q
what is the reactant always needed for combustion reactions to occur?
A
oxygen
7
Q
general equation for respiration
A
glucose + oxygen → carbon dioxide + water
8
Q
general equation for photosynthesis
A
carbon dioxide + water → glucose + oxygen
