Ayuda con la tarea de química

El solucionador de problemas de química de QuetionAI es una herramienta de tutoría de química para escuelas secundarias que puede resumir reacciones y ecuaciones químicas clave para los usuarios en tiempo real y tiene un potente sistema de aprendizaje para que incluso los estudiantes con una base débil puedan dominar la química fácilmente..

Ya no tendrás que preocuparte por las propiedades elementales de la tabla periódica. Aquí podrás acceder fácilmente a las reacciones químicas y principios de reacción correspondientes a cada elemento. Deducir la estructura original de moléculas y átomos a partir de los fenómenos macroscópicos que se pueden observar es una técnica de investigación química que siempre hemos defendido.

Use the equation below to answer the following question: Fe+Cl_(2)... FeCl_(2) A student wants to prove the concept of limiting reactants to his labmates during class. If the student adds 56g of Fe to 71 g of Cl_(2) , what will the likely result of the reaction be in regards to limiting/excess reactants? Because there is more Cl_(2) chlorine will be the excess reagent and iron will be the limiting reagent. Based on the balanced equation, there is an equal amount of iron and chloride, so the reactants will be fully consumed with neither limiting nor in excess. There is an equal amount of iron and chloride; however because of the 1:2 Fe:Cl nature of the reaction iron will be in excess and chlorine will be the limiting reagent. Although there is more Cl_(2) it takes two chlorine atoms to react with every one iron atom, so iron will be the excess reagent and chlorine will be the limiting reagent.

Based on the balanced equation, there is an equal amount of iron and chloride, so the reactants will be fully consumed with neither limiting nor in excess. There is an equal amount of iron and chloride; however,because of the 1:2 Fe:CI nature of the reaction , iron will be in excess and chlorine will be the limiting reagent. Although there is more Cl_(2) it takes two chlorine atoms to react with every one iron atom, so iron will be the excess reagent and chlorine will be the limiting reagent.
