Write, predict the products, and balance the following single displacement reactions. Be sure to include states of matter. If the reaction does not occur, you do not need to do anything but write (NR) for no reaction: Aqueous sodium sulfate and solid iron (II)

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

Ibelieve it's temperature! i'm not 100% sure.
