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.
- Question 1(1 point) 2H_(2)(g)+O_(2)(g)arrow 2H_(2)O(g) A student wants to calculate the amount of water (H_(2)O) in grams produced from 3.5 moles of oxygen gas (O_(2)) 126 g b 0.229 63g d 3.949
- Scientists sometimes want to show whether more energy is used or released during a chemical process. They do this by adding the word energy to the chemical equotion. If more energy is used than is released during a chemical process, "energy" should appear on the same side of the equation as the reactants. If more energy is released than is used, "energY" should appear on the same side of the equation as the products. The energy used in photosynthesis is light energy.which is captured by pigments in plant cells called chlorophyll, Which of the following belanced chemical equations accurately summarizes photosynthesis? 6CO_(2)+6H_(2)Oarrow C_(18)H_(12)O_(6)+6O_(2)+light ene 6CO_(2)+6H_(2)O+lightenergyarrow C_(4)H_(12)O_(6)+6O_{2
