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 are different forms of an element that have different numbers of neutrons? ions isolopes compounds moleoules
- 11. How many molecules are contained in each compound? a. 1.35 mol of carbon disulfide (CS_(2)) b. 0.254 mol of diarsenic trioxide (As_(2)O_(3)) c. 1.25 mol of water d. 150.0 mol of HCl
- The mole is a number equal to 602 ,000,000,000,000 ,000,000,000 or 6.02times 10^23 Solve the following problem to give you an idea of how large a number this is: How many dollars would each of the 7 billion (7,000,000 ,000) people of the world get if you distributed 1 mole of pennies to each of them? Converting moles to representative particles: representative particles=molesx(6.02times 10^23reprrssentative particles)/(1mole) Converting representative particles to moles: moles=representative particlesx(1mole)/(6.02times 10^22)representative particles 1. How many moles of magnesium is 1.25times 10^23 atoms of magnesium? 2. Determine the number of atoms that are in 0.58 mol of Se. 3. How many moles of barium nitrate (BaNO_(3)) contain 6.80times 10^24 formula units?
- What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valenc electron? energy mass neutrons electrons
