Actividad 3. En una experiencia se pusieron 10 g de una sustancia A y cierta cantidad de otra sustancia B en un crisol. Después de calentar durante cierto tiempo, se obtuvo un sólido AB cuya masa era de 15,3 g. Se pide: a) Calcula los gramos de B que se combinaron.
b)Si queremos obtener un kilo del sólido AB. ¿Cuántos gramos de A
necesitaremos? Necesito ayuda por favor

u i forgot the answer?

the answer is b & c i believe : )

dynamic equilibrium is the answer.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
