Well I know zinc reacts with hydrochloric acid in the equation:
$$Zn+2HCl===>ZnCl _{2}+H_{2}$$

anonymous · Answer

Gold doesn't chemically react with acid but it does dissolve in it.

anonymous · Answer

Copper does react with sulphuric acid in the equation:$$Cu+H _{2}SO4===>Cu ^{2+}+SO _{4} ^{2-} +H _{2}$$
It produces one copper with 2 extra electrons so i wrote 2- up there and one SO4 with 2 extra electrons so i wrot (2-)

oh and i almost forgot one molecule of diatomic hydrogen

aaronq · Answer

gold actually doesn't dissolve in anything BUT aqua regia $(HNO_3 \;\&\;H_2SO_4)$

anonymous · Answer

yah but thats an acid right? @aaronq

aaronq · Answer
