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.
- Write the names for the following covalent compounds: 9) P_(4)S_(5) __ 10) O_(2) __ 11) SeF_(6) __ 12) Si_(2)Br_(6) __ 13) SCl_(4) 14) CH_(4) __ 15) B_(2)Si __ 16) NF_(3) __
- FRQ (Show all work for full credit) A student wants to determine the Molarity of an unknown solution of LiOH To determine this, the student measures ou 50mL of 0.5M H_(2)CO_(3) The student adds the LiOH to the acid until a faint pink color appears. The student checks the buret and calculates that 34.45mL of the LiOH were added. 1. How many moles of H+ were in the flask before the base was added? (3pts.) 2. What is the pH of the acid before the addition of LiOH? (2pts.) 3. At the moment the pink color appears, how many moles of LiOH have been been added to the flask? (2pts.) 4. Given all of the data gathered from the titration,what is the Molarity of the LiOH? (3pts.)
- Which of the following gases would you predict to be most non-ideal? CO_(2)(g) He(g) CH_(4)(g) N_(2)(g)
- Which of the following gas systems exhibits the most ideal behavior? one mole of He (g) at 100K in a 100 liter container one mole of He (g) at 100K in a 10 liter container one mole of He (g) at 400K in a 10 liter container one mole of He (g) at 400K in a 100 liter container
- For alkenes or alkynes, the unsaturation must get the smallest possible number to name them. True False
