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 4 (2 points) You dissolve 0.46 moles of KCl into 4.0 liters of water.What is the molarity of the solution? molesh.(Answer using 2 significant figures) Blank 1: square
- 1. The unbalanced equation for the reaction between aquenus solutions of alminum titrate and sodium phosphate is as follows. Al(NO_(3))_(2)(aq)+Na_(3)PO_(4)(aq)arrow NaNO_(3)(aq)+APO_(4)(s) What are the coeffoints for balancing this chemical equation? 1,1,3,1 3,9,3,1 1,1,1,1 3,1,3,4
- Question 3 (2 points) George wants to make a 0.1M solution of LiCI. He carefully measures 0.42g of lithium chloride into a flask and adds 100mL of water. He stirs the solution until all of the crystals are dissolved.What is the result? a George's calculation included mL instead of L. His solution has a molarity of 0.001moles/L b George should not have stirred the solution. His solution's molarity would have been correct otherwise. c. George did not calculate the molar mass of LiCl correctly. His solution has a molarity of 2moles/L. George did not use the correct amount of water. His solution has a molarity of 10moles/L. George used grams instead of moles in his calculation. His solution has a molarity of 70moles/L f George correctly made the solution
- What should be done with low-hydrogen electrodes if they have gotten wet? dry them for at least 10 days re-bake them for double the standard time discard them use them only with carbon steel
