Can someone help me with this?
Cu3(CO3)2(OH)2 solid+ H2SO4 aqueous--------->
and does it decompose after reacting?

This sort of thing, is hard to learn on your own, but we can try to piece it together.  Consider H2SO4 -- does it do anything special, when it's aqueous?  Can you write a reaction for that.  Can you look at the atoms in your reactants, and rearrange them into chemicals you've heard of?  You can try to start along those lines, and see what you can learn.

well i think its Cu3(CO3)2(OH)2 + H2SO4--->CuSO4 + H2O but CuSO4 is blue....after a day or so mines turned green aq

Go check wikipedia for the mineral azurite, which is what Cu₃(CO₃)₂(OH)₂ is.  There is a lot on that page, regaring what it is, how it weathers over time, what it's been used for, etc.  And yes, even how colors change over time.  My childhood chemistry set included this mineral, and I played with it a lot, back in the day.
