Question about "que" and "cual"
When & why do you use one or the other? They seem to mean the same thing
Jsanthara's link is very good, but, if you are as new to learning Spanish as you seem to be, by some of the questions you have posted,then it may be a little difficult for you.
Your confusion may lie in the fact that both words are sometimes translated as what.
¿Cuál es tu nombre? What is your name? or ¿Qué hora es? What time is it?
Of all the names that could be yours, which one is yours? ¿Cuál es tu nombre? "Which" is your name? Even when cual is translated to that or who it, usually can still be brought back to which.
The words that describe time are repeated every 12 (or 24) hours, but, now only happens once in all of history. ¿Qué hora es? "What" time is it?
This is not a complete answer,but should get you started.
Please refer to this reference article on the subject.
