Rather simple chemistry questions:?

Glad you have the answers. Funny that you neglected to indicate them, makes one wonder why. Based on the vast number of questions submitted by lazy children uninterested in doing their own work, what you you conclude when someone claims to "know the answer" but fails to indicate them? Wouldn't you think that s/he would want to know (if any are wrong) why they are wrong and so put them down. Who knows maybe fragile ego, maybe just lazy, maybe too arrogant.
