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.
- decomposes to dinitrogen monoxide and water according to the following equation. NH_(4)NO_(3)(s)arrow N_(2)O(g)+2H_(2)O(l) In a certain experiment.nitrate is decomposed. Find the mass of water formed. 10.7 g 5.3g 21.4g 711.9 g Multiple Choice 10 points
- According to the solubility curve, the solubility of NaCl is 40 g in 100 g of water at 90^circ C Which solution below is saturated? 80 g NaCl in 300 g water 85 g NaCl in 200 g water 30 g NaCl in 100 g water 10 g NaCl in 50 g water
- According to the solubility curve, the solubility of KCl is 30 g in 100 g of water at 10^circ C Which solution below is unsaturated? 20 g KCl in 100 g water 20 g KCl in 50 g water 40 g KCl in 100 g water 80 g KCl in 200 g water
- Read the lab report conclusion and then answer the question. Based on the data gathered, we measured the boiling point of water as 99.51 degrees Celsius. The error against the expected measurement was 0.49 percent Sources of error may have been impurities in the water,contamination or the equipment, or human error in reading the thermometer. If we repeated the experiment, we might achieve more accurate results by sterilizing our equipment, using distilled water, and verifying that the thermometer's readings are correct. Who is the primary audience? a writer for a popular science magazine scientists who study water quality a high school science teacher
