Calcular la cantidad en moles del tetraóxido de hierro que se pueden obtener a partir de 40 gramos de agua (90%) y 25 g de hierro sólido (98%), ademas, determine el porcentaje de rendimiento de la reacción 100 si en un laboratorio luego del proceso se obtuvieron 15 gramos del tetraóxido de hierro.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
