Ejercicios Ascenso Ebulloscopico: 1- Calcula el ascenso ebulloscópico de un sc acuosa de sacarosa de concentración 0,22 m. sabiendo que Ke para el agua es 0,51ºC/m.

2- Calcular la temperatura de ebullición de una solución acuosa 0,3m Teb agua a presión normal: 100ºC y Ke: 0,51ºC/mol.

3- Calcular el ascenso ebulloscópico de una solución de ClNa 0,44m, sabiendo que Ke:0,52ºC/mol.

4- En 500 ml de agua se disuelven 20 g de cloruro de potasio. Calcular la temperatura de ebullición de la solución

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

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.
