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.
- Multiple Choice 1 point How many moles of oxygen gas (O_(2)) is needed to produce 18.0 liters of CO_(2) at STP? CH_(4(g))+2O_(2(g))arrow CO_(2(g))+2H_(2)O_((l))
- Consider the equation: 5A+2Barrow C+D You react 7 moles of A with 4 moles of B. Which of the following is true: A is the limiting reactant because you need 10 and you have 7 B is the limiting reactant because 7 A molecules react with 4 B molecules B is the limiting reactant because you have fewer moles of B than A A is the limiting reactant because of its lower molar mass
- P_(4)+3O_(2)arrow P_(4)O_(6) What is the limiting reactant is 12 moles of P_(4) react with 15 moles of O_(2) P_(4)= P_(4)O_(6) O_(2) none of the above
- Stoichiometry Practice Hydrogen sulfide gas reacts with oxygen gas to form sulfur dioxide and water according to the following equation. 2H_(2)S(g)+3O_(2)(g)arrow 2SO_(2)(g)+2H_(2)O(g) What volume of hydrogen sulfide is needed to react completely with 4.2 L oxygen? 4.2 L 8.4 L 1.9 L 2.8L
- How do real gases deviate from ideal behavior at high pressures? They condense into liquids. They follow the ideal gas law exactly They expand to fill the container. Their particles become closer together, creating intermolecular forces.
