The Attempt at a Solution...
I have been doing a research around the physics behind bungeejumping and i need some new ideas. Some of the ideas i already have done are: 1) friction while bungee jumping 2) bunjee jumping (but in water instead of just air) ...
i need some creative ideas for my reasearch.
thank you,

Sorry, i made a mistake while typing. it should be:
4 FeCr2O4 + 8 K2CO3 + 7 O2 --> 8 K2CrO4 + 2 Fe2O3 + 8 CO2
Thank you and i have another questi0n: can K2CrO4 the smallest limiting reagant?
i took it as the smallest limiting reagent .. and i calculated the weight of the other susbstances...
1) K2CrO4 is produced by the reaction of FeCr2O4 with K2CO3 and O2 in a high temperature. This reaction also produces Fe2O3 and CO2.
If 169 kg FeCr2O4 reacts with 298 kg K2CO3 and 75 kg O2 and so it produces 194kg K2CrO4 then calculate the efficiency of this reaction.2) The equations is: 4...
Thanks for your advises !
Can you explain how it could be done with graphite.. i searched for it and i got an experiment but it isn't so clear what was being done in the video..
