2Fe2O3 -> 4Fe+3O2 changeHrxn= +824.2 KJ

The decomposition of 57.0 g of Fe2O3 results in

The release of 23500 KJ of heat
The absorption of 147 KJ of heat
The absorption of 23500 KJ of heat
The absorption of 294 KJ of heat
The release of 294 KJ of heat
The release of 147 KJ of heat

  • Chemistry - ,

    This is done just like your last problem except this one is endothermic so energy is being absorbed (because of the + sign on delta H).

  • Chemistry - ,

    the release of 147 kj of heat

  • Chemistry - ,

    Its the absorption of 147kJ
