chemistry enthalpy A-Level help?? Watch
I thought we could use the ‘products take away reactants’ method for enthalpy of formation & ‘reactants take away products’ for combustion, but we have a new teacher this year who told me it’s better to use the method where you draw out the arrows & stuff to find it but I get confused easily with those & he said not to use the equation method bc it’s easy to make a mistake with it...
is that true bc the method I’ve been using is nowhere in the revision books or guides so I’m worried if I actually do need to learn the diagram method instead even tho I struggle with it.
Thank you for any advice!! Xx
I used to teach it the way you can do it, but a long time ago, I found that using arrows tended to be easier for my students to understand (and apply correctly), so I swapped.
Hope this helps
