a que temperatura cpngelara el agua de un radiador de automovil si se agregan 1 litro de dietilenglicol a 2 litros de agua si se sabe que hay una dencidad de 1,118 gramos/mol la masa molecular del dietienglicol es 106 gramos / mol

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.
