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 skeleton equation H_(2)+O_(2)arrow H_(2)O Which explanation correctly summarizes the difference between the substances on the left and right sides of the equation? The left side of the equation represents the solutes, or the solid substances present before B solution farms. The right side of the equation represents the solvent, or the substance used to dissolve the solute. The left side of the equition represents the reactents, or the substances present before the reaction takes place.The right side of the equation represents the products or the substances formed after the reaction has occurred. C The left side of the equation represents the colalyst, or the substance used to speed up the reaction. The right slde of the equation represents the material state of the renction system D The left side of the equation represents the products, or the substances formed efter the reaction has accurred. The right side of the equation represents the reactints, or the substances present before the reaction takes place.

propane tank inspector detected rust (Fe_(2)O_(3)^L) inside an empty tank.The empty cylinder valve was not closed, exposing the interior of the tank to humid air. Select the equation that describes in synthesis reaction for the formation of rust. A Fe_(2)O_(3)arrow 2Fe+O_(2) B 4Fe+3O_(2)arrow 2Fe_(2)O_(3) C FeCl_(2)+H_(2)Oarrow FeO+2HCl D Fe_(2)O_(3)+3COarrow 2Fe+3CO_(2)

The equation for propane burning to form carbon dioxide and water is: C_(3)H_(8)+5O_(2)arrow 3CO_(2)+4H_(2)O If the amount of avallable oxygen is reduced due to limited ventilation, carbon monoxide (CD) is also produced by the reaction: C_(3)H_(8)+4O_(2)arrow CO_(2)+[]CO+4H_(2)O Balance this reaction by selecting the correct coefficient for CO on the pr product side of the equation A 1 B 2 C 3 D 4

.produce 340 grams of carbon dioxide ( at STP? C_(3)H_(8)+5O_(2)arrow 3CO_(2)+4H_(2)O
