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 the percent error obtained from this lab and explain some sources of error that would account for the discrepancy seen, if any.Which student employs correct scientific reasoning? Student 1: If the reaction was not allowed to go to completion the sodium bicarbonate would not have fully decomposed , making the final mass higher than the theoretical. Student 3: The student didn't weigh the masses correctly therefore human error is the main source of discrepancy. Student 2: If the baking soda was not heated long enough, the final mass of solid product would be low.
- For the following unbalanced equation, what type of reaction is NH_(3)arrow N_(2)+H_(2) combustion decomposition double replacement single replacement synthesis
- (9g^3s^6)/(3gs^2)=3g^2s
- Why is bromine (Br_(2)) a liquid at room temperature while fluorine (F_(2)) is a gas? Both have london dispersion forces , so what contributes to the different states of matter for those forces.
- For the following unbalanced equation, what type of reaction is H_(2)+O_(2)-H_(2)O single replacement combustion decomposition synthesis double replacement
