Hi guys!
I have real problems with the reactions. I can not get the point about them.
For example:
Cu + HCl ----> No reaction
Dil. H2SO4 + Ag ----> No reaction
Mn + H2O ----> No reaction (Hot water Mn(OH)2 + H2)
Dil. H2SO4 + Hg ----> No reaction
CaCl2 + Cr ----> No reaction
Mg(NO3)2 + NaCl -----> No reaction
Sorry for silly question but can you please explain me a rule about the reactions or please advise what exactly should I read
.
I started to study chemistry this year, and as you understand I am starting from the very beginning.
I would appreciate any help.
Thanks!
