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.
- Three students are asked to discuss what would happen to calculated molar volume if the magnesium did not react to completion. Which student employs correct scientific reasoning? If the magnesium did not react to completion then the extra hydrochloric acid would add to the final mass calculated for hydrogen gas causing the molar volume to be too high. If the magnesium did not react to completion too much hydrogen gas would be produced causing the stopper to pop out of the Erlenmeyer flask and this would cause the molar volume to be too low. If the magnesium did not react to completion the calculated theoretical moles of hydrogen produced would be too high and this would cause a decrease to the calculated molar volume.
