Cu(NH3)SO4 or [CU(NH3)4]SO4
Cu2+ is more stable, though Cu+ compounds are known
Cu(s) + 2AgNO3(aq) ---> Cu(NO3)2(aq) + 2Ag(s) So you need half as many moles of Cu. Thus 5.8/2 = 2.9 moles of Cu are needed.
Cu from "cupro", the Latin word for copper.
Covalent bonds are formed between a metal and a non-metal. Cu is copper, a metal, so it will react with F to form CuF, a compound with ionic bonds.
Cu donates electrons to Br to form CuBr. It is a crystalline compound. The bonds have mixed ionic and covalent characters.
This reaction can occur according to the equation Cu + AgNO3 = CuNO3 + Ag or according to the equation Cu + 2 AgNO3 = Cu(NO3)2 + 2 Ag, depending on whether Cu(I) or Cu(II) nitrate is formed.
