"My scissors will be on my desk."
Translation:Mis tijeras estarán en mi escritorio.
yes it´s wrong.
If you see an preposition of place after ´´to be´´ it means ´´estar´´
SER is used to describe characteristics or qualities ( color, shape, material of which something is made out of, size, physical characteristics, and personality.)
Ex.: -the snow is white = la nieve es blanca
-i am tall = yo soy alto
ESTAR is used to express location, transitory aspects, and characteristics that are NOT inherant property of a noun, such as how something/someone looks, feels or tastes at a given moment.
Ex.: -i am at home = estoy en casa
-the coffee is cold = el café está frío
No, in spanish the present progressive is a composed tense with conjugated verb "ir" + a + infinitive, and it's related to an action that may occur in the near future. Exmpls. Voy a dormir, él va a morir.
Meanwhile, future is always the simple, conjugated verb. Using the same examples: dormiré, él morirá.
Notice then, that there are 2 diferent tenses, and ind spanish, and we use one or another more often depending on the sutuation.
