i know im asking too much, im just panicking real hard 
so can anyone please tell me the products when:
Acid + Metal -->metal salt + hydrogen
Acid + Base -->metal salt+ water
Acid + Metal Carbonate -->metal salt +carbon dioxide+water
How metal nitrates breakdown
and how the boiling and melting points change down group of group VII
Really sorry for the trouble 
as we go down the group of halogen , m.p. and b.p. is increasin
metals of group 1 , well they give u following:
metal nitrate ( exceot for Li)--> metal nitrite + oxygen
metals for group two (and Li) and transition metals give u :
metal nitrate --> metal oxide + nitrogen gas + oxygen
(remeber group TWO means TWO gases ...group ONE means ONE gas given off

)
don't panic ...relax and have faith and god and have sonfidence in urself mate
