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.
- Vocabulary: Arogadro's number:balanced equation, cancel, coefficient,conversion factor, dimensional anaysis formula mass, molar mass -mole, molecular mass, staichiometry Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A 250 mL glass of orange juice contains 22 grams of sugar. How much sugar is in a two-liter (2,000 mL) bottle of orange juice? __ 2. It requires two sticks of butter to make a batch of 20 cookies. How much butter will it take to make 150 cookies? __ Gizmo Warm-up Just as a cook follows a recipe to decide how much of each ingredient to add, a chemist uses stolchiometry to determine the amounts of substances involved in chemica reactions. The Soichiometry Gizmo alous you to try your hand at figuring out the amounts of reactants and products that take part in a chemical reaction. To begin, check that this equation is shown: New equation Fe_(2)O_(3)(s)+300(s)-2Fe(s)+300_(2)(s) New question (CO) (F_(2),O_(3)) dison
- Multiple Choice 10 points What is the molar mass of Cl_(2) 17g/mol 35.5g/mo 71.0g/mol 89g/mol
- What is a limiting reactant? the product that you can make the most of the reactant that is in excess the reactant that determines how much product can be made the amount of reactants that react with each other
- What is the limiting reagentwhen 150,0 g of nitrogen reacts with 321 g of hydrogen? N_(2)(g)+3H_(2)(g)2NH_(3)(g) There is not a limiting reagent Nitrogen Gas Hydrogen Gas Ammonia
- 2H_(2)+O_(2)arrow 2H_(2)O 1) How many moles of water form if 10 moles of oxygen react? 2) How many moles of hydrogen are used to make 368 of water?
