Determine the direction of electron flow and label the anode and the cathode. label each electrode as negative or positive. drag the appropriate labels to their respective targets. reset e − → ← e − cathode (+) anode cathode anode (+)

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.
