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.
- If 10 mols of Hydrogen gas was available to react with excess Oxygen, how many grams of water would be produced? 2H_(2)+O_(2)otimes 2H_(2)O 180 g 90.0 g 3.6 g 45.0 g
- When sodium bicarbonate and acetic acid are combined in a beaker and allowed to run to completion, a small amount of sodium bicarbonate remains unreacted at the bottom of the beaker at the end of the experiment. This means that the sodium bicarbonate is the __ in this experiment. limiting reactant product catalyst excess reactant
- Among the elements of the main group, the general trend in the first ionization energy moving across a period is not followed between group 2 and group 13 Which best explains these exceptions? The ionization energy decreases because the full s orbital shields the electron entering the p orbital. The ionization energy increases because the full s orbital shields the electron entering the p orbital. The ionization energy decreases because the stability of the half-full p subshell is increased. The ionization energy increases because the stability of the half-full p subshell is increased
- 2H_(2)+O_(2)arrow 2H_(2)O How many moles of water would be produced from the reaction of 8.10 moles of hydrogen gas reacting with oxygen gas? 2.10 moles 4.05 moles 8.10 moles 16.2 moles
- The elements least likely to form bonds are found in which group? 15 16 17 18
