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.
- Consider the combustion reaction for acetylene. 2C_(2)H_(2)(l)+5O_(2)(g)arrow 4CO_(2)(g)+2H_(2)O(g) If the acetylene tank contains 37.0 mol of C_(2)H_(2) and the oxygen tank contains 81.0 mol of O_(2) what is the limitin reactant for this reaction? O_(2) CO_(2) H_(2)O
- Which statement correctly describes the relationship between reactant and yield? The actual yield is calculated from the amount of the excess reactant present The actual yield is calculated from the amount of the limiting reactant present The theoretical yield is calculated from the amount of the excess reactant present The theoretical yield is calculated from the amount of the limiting reactant present
- Which describes the volume of 1 mol of gas at standard temperature and pressure? The volume is greater for a larger mass of gas. The volume is the same for any gas The volume depends on the size of the container. The volume varies with the pressure.
- Limiting Reactant and Percent Yield Which statement correctly describes the relationship between reactant and yield? The actual yield is calculated from the amount of the excess reactant present The actual yield is calculated from the amount of the limiting reactant present The theoretical yield is calculated from the amount of the excess reactant present. The theoretical yield is calculated from the amount of the limiting reactant present.
