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.
- Lithium phosphide (three lithium atoms with one phosphorus atom)has a chemical formula of Li_(3)P. If you look at the total atomic mass of Li_(3)P does Jithium or phosphor Scroll More b more of it is impossible to tell they are exactly the same phosphorus lithium
- In a lab experiment you obtain 55.62 grams of your product, but when using stoichiometry to determine how much product you should have gotten, you found that your reactants should have produced 75.87 grams. What was your percent yield? Round your answer to the nearest 0.01 and include units (but not the substance formula). Your Answer: square square Answer units
- 4/10 What percentage of the total atomic mass of magnesium bromide (MgBr_(2)) is composed of magnesium? 87% 63% 13% 43%
- 4. Determine the number of protons, neutrons, and electrons in each of the following species: a. Cl^35_(1) b. Al C. K^41
- You run an experiment according to this equation: 2HCl+CaCO_(3)arrow H_(2)O+CaCl_(2) +CO_(2) When running your lab you started with 62 .16 grams of HCl and 50.18 grams of CaCO_(3) If, after the reaction finishes, your products have a total mass of 80.10, what was the percent yield? Round your answer to the nearest 0.01 and include units! Your Answer: square square Answer units
