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.

Some molecules are always found in pairs These are called __ molecules. How many atoms of each kind are there? __ Write in the name of the molecule in the blank.

Lisheth poura 50 mi of dissulted (pure) water into a large cup.She then puts i conductivity meter in the cup to test whether the water conducts electricty Will her results indicate that water conducte electricity (yes or no)? __ She pours 025 grams of ougar into the cup, and most of it sinks to the bottom. Some of the sugar dissolves, but the molecules only partially break apart Based on this information, in sugar a atrong electrobyte, weak electrolyte or non-electrolyte? __ Lirbeth wants the sugar to dissolve better, so she puts the cup in the refrigerator. Is the successfu? __ When she removes the cup, some of the sugar still has not dissolved, so she takes apoon and crushes the sugar in the bottom of the cup into smaller crystals. Does this help? __ Eventually the notices that some of the sugar still has not dissolved so she addenonpolar coconut oil to the cup. Does thin help? __ Word Bank non-electrolyte yes no yes strong electrolyte no you weak electrolyte Blank 1 square Blank 2: square Blank 3: square Blank square Blank 5: square

Water is sometimes removed from the products of a reaction by placing the products in a closed container with excess P_(4)O_(10) Water is absorbed by the following reaction. P_(4)O_(10)+6H_(2)Oarrow 4H_(3)PO_(4) What is the mole ratio of water to H_(3)PO_(4)?Donot simplify the ratio. H_(2)O:H_(3)PO_(4)=square :4 DOM: 19

Question 2 (2 points) How much water do you need to add to 194 moles of ammonia crystals to create a24 molar solution? __ 1. (Answer using 2 significant figures) Blank 1: square
