hello everyone (Who tried to help me)
the problem was that : I didn't understand the question.
Apparently I had to choose one compound that suitable for each feature
MgH2 fits number 3.
NH3 fits number 1.
H2O fits number 2.
THIS IS WHY I DIDNT KNOW HOW TO TRY TO ANSWER THE QUESTION!!!
hope next time before you Complain about the violation of forum rules you will stop and think that the person who asked the question want to answer it by himself (because you won't do the test in his place)
and also that person don't like waste your time like he does not like to waste his time.

You have no right to yell at people for asking you to follow the rules.  If you don't want to follow them, you can leave, or you can keep trying to ignore them, and we'll ask you to leave.

My opinion:  You are simply lazy.  Perhaps you've been conditioned that repeated whining gets results eventually.  But in this thread in particular, anyone can count how many times you just complain, instead of applying what you've just been taught.
