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.
- You run an experiment according to this equation: 2HCl+CaCO_(3)-gt H_(2)O+CaCl_(2) +CO_(2) When running your lab you started with 62 .16 grams of HCI 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
- 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
- Methane burns according to the equation CH_(4)+O_(2)... CO_(2)+H_(2)O You burn 1.77 grams of methane (CH_(4)) in excess oxygen and collect 1.79 grams of water. What is the percent yield for this reaction to the nearest 0.01 ? Your Answer: square square Answer units
- An experiment using the reaction below produces 49.96 grams of chlorine gas (Cl_(2)) What mass of HF is produced by this experiment? Round your answer to the nearest 0.01 and remember to include units and substance! HCl+F_(2)... HF+Cl_(2) Your Answer: square square
- Find the percent composition of each element in CaSO4. Be sure to add the % sign and the element. "Ca is the 1st blank "S is the 2nd blank" 'O is the 3rd blank 'GO ONE PLACE PAST THE DECIMAL IN ANSWERS" Example: If you calculated 12.346% element X, you would write your answer as: 12.3% X square square square
