1- El helio (He) es un gas valioso que se Utiliza en la industria, en las investigaciones donde
Se requieren bajas Temperaturas, en los tanques para
buceo profundo, y para inflar globos. ¿Cuantos
moles de He hay en 6.46 g de He?

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The answer would be
