Hey! This is probably a silly question, but would there be any reaction between the following, essentially Malachite placed in regular, room temperature tap water.
Cu₂(CO₃)(OH)₂+H₂O
There are many misconceptions about this on various web pages, such as it releasing toxic gases when it gets wet, but I cannot see any reason for this. Not being a scientist however I thought it best to check with the experts!

Malachite is very stable, can be seen on copper made roofs. The only thing is that slowly coper get dissolved. So the amount of copper will be higher in the water. There will be no gas. Some carbondioxide nothing else.

Thanks for your reply! I figured it was probably the case with my basic understanding, but just wanted to check further in case there was something I was missing!
