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.
- Which interaction produces dispersive forces by creating temporary dipoles that induce dipoles in other molecules? dipole-dipole hydrogen bonds dipole-induced dipole induced dipole-induced dipole

- Ming has two unknown substances. One is nonpolar,and the other is polar. Which process would most likely help Ming identify which substance is polar and which is nonpolar? Test the boiling points The polar substance should have a lower boiling point because of its dipole-dipole forces. Test for an odor The nonpolar substance should have a higher volatility and stronger odor because of its London dispersion forces. Test the boiling points The nonpolar substance should have a higher boiling point because of its hydrogen bonds. Test for an odor.The polar substance should have a higher volatility and weaker odor because of its dipole-dipole forces.
- Which statement best explains why water has a higher boiling point than ethane? Ethane molecules are smaller than water and can move faster. Water molecules need relatively less heat energy to move. Water molecules form hydrogen bonds, which cannot be broken by heating water. Ethane molecules have no hydrogen bonds and need less energy to separate.
- Part A CHEMISTRY Under standard almospheric conditions, water will not remain a liquid if its temperature is less than or equal to 0^circ C or if it is greater than or equal to 100^circ C Suppose you have a cup of water that is room temperature, or 20^circ C Write a compound inequality to represent the number recorees liquid. temperatire of the cup must change to no longer be A) 0leqslant 20-cleqslant 100 B) 0leqslant 20+cleqslant 100 C) 20+clt 0or20+cgt 100 D) 20+cleqslant 0or20+cgeqslant 100
