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.

__ = the reactant that limits the amount of the other reactants that can combine, and the amount of products formed in a chemical reaction. __ = the substances that is not used up completely in a reaction. Each reaction has a limiting reactant. It works the same way as in baking. Imagine if you were to go home and mix up a batch of cookie dough to make your favorite chocolate chip cookies and discover that your little brother has been eating the chocolate chips as after-school-snacks and there are not enough chips left to make the whole batch of dough into chocolate chip cookies. The amount of chocolate chips limits the number of chocolate chip cookies you can make You will have to decide what else you can put in the batter to make a different kind of cookie. In chemical reactions, one of the reactants will run out before the other, this is the __ because it controls how much product will be made. The reactant that is left over (like the left over cookie dough without chocolate chips is the __ . To determine which reactant is limiting and which is in excess you must do TWO stoichiometry problems. You will be given two pieces of information and you must use each one to determine the number of moles of product. You must solve for moles because it is the common denominator. The reactant that makes the least amount is the limiting reactant and the other is the excess reactant. Example: If 5.01g of calcium hydroxide react with 2.2g of potassium bromide , how many moles of calcium bromide will be formed? Identify the limiting and excess reactant. Step 1: Write the balanced chemical equation. Ca(OH)_(2)+2KBrsimeq 2KOH+CaBr_(2)
