Sanzida conducted an experiment that required a wire carrying a current to be wrapped around a metal core. When she placed the south pole of a bar magnet near the rod, she observed the magnet move toward the rod. Which conclusion can Sanzida draw from this experiment?

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.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
