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.
- When dissolving a gas into a liquid, which of the following will INCREASE the solubility of the gas? A. decreasing the temperature B. increasing the temperature C. increasing the pressure D. Both A and C are correct
- Fill in the blank to the set up of this question: How many grams of magnesium chloride are in 771 moles of MgCl2 square square 1 mol MgCl_(2)
- Calculate the ratio of H^+ ions to OH^- ions at a pH=6. Find the concentration of H^+ ions to OH^- ions listed in Table B of your Student Guide. Then divide the H^+ concentration by the OH^- concentration. Record this calculated ratio in Table A of your Student Guide. Compare your approximated and calculated ratios of H^+ ions to OH^- ions at a pH=6. Are they the same?Why or why not? Record your explanation in Table A. What is the concentration of H^+ ions at a pH=6 square mol/L What is the concentration of OH^- ions at a pH=6 square mol/L What is the ratio of H^+ ions to OH^- ions at a pH=6 square :1
- (4) 7. For your first trial, find how many moles of sllver nitrate are present at the beginning. Show your work. square
- Calcium carbonate decomposes to form calcium oxide and carbon dioxide according to the reaction: CaCO_(3)(s)arrow CaO(s)+CO_(2)(g) . What mass of calcium oxide is produced from the decomposition of 23.6 g of calcium carbonate? (23.6gCaCO_(2))/(100.gCaOCl_(3))times (1molCaO)/(1molCaOO_(2))times (56.1gCaO)/(1molCaO)=132g Number 5 is a preview of the types of calculations you'll learn to do in this worldaudd
