4.10 understand that chemical reactions in which heat energy is given out are described as exothermic and those in which heat energy is taken in are endothermic
In an exothermic reaction heat is given out. Because bonds are made which gives out energy.
Think expelled; exit; exo.
In a endothermic reaction heat is taken in. Because bonds are Broken which requires energy.
i think she's changed the exothermic/ endothermic bit but forgot to change the other bit. so i think its exothermic makes heat energy while breaking bonds (not making them)
i think it is the other way around? http://www.bbc.co.uk/schools/gcsebitesize/science/add_edexcel/chemical_reactions/energychangesrev2.shtml
ReplyDeleteWow, thank you! That was a bit silly ;P
ReplyDeleteHannah you have it written correctly
