Porque vs por qué
 

Explica la diferencia entre estos, por favor.:thinking::)

Gracias.:)

¿Por qué comes chocolate?
Porque me gusta

Why do you eat chocolate?
Because I like it.

porque - answer (because)
por qué - question (why)

Tu explicación es muy bueno (buena/bien).:thinking::)

Gracias:)

Thank you Vita for the question,
ookami for the answer.

is there any situation,

where Por qué or Proque are spelled in a different ways?

You are welcome:), Joseph. Aside from your question I also have another question for the Spanish experts. Does qué by itself always spelled with the accented e?

Thank you.

No. "Que" as a conjunction -its more frequent use- bears no stress mark

Thank you. Will you give me some example please.:)

You're welcome :)

Le dije que cierre la ventana.
I told her/him to close the window.

El auto que se rompió era mío.
The car that broke down was mine.

where in that sentence is I implied?
what is the exact meaning of,
Le Dije
Told, I am misunderstanding the nouns.
*( how did you get that? )*

Spanish is a language where subject is often tacit.
The conjugated verb "dije" already has the subject expressed. The fact that each pronoun has its own conjugation tells who the subject is.

"Le" is an indirect object pronoun for the third person singular.
