Ken In San JoWhen is "cual es" used and when is "qué es" used? For example, one says, "Cual es su nombre?" and "Qué es eso?". Is there a rule that can be applied?
!Nos vemos pronto!
The same happens in english with "Which" and "What"
Which car do you like?
What´s that?
Is the same, for example, you use "Which/Cual" to ask about a choice when you have a lot of opportunities about that and you ask to the other person, which prefer or which he/* choose. And you use "What/Que" to ask about the meaning of something, here you have some examples:
¿Cúal auto prefieres? -- Está preguntando cual auto la persona prefiere, de los muchos que tiene para elegir/escoger
¿Qué es eso? -- Está preguntando acerca del significado de alguna cosa.
Espero que lo hayas entendido, es solo práctica, cualquier cosa pregunta
