German silver varies in composition, the percentage of the three elements ranging approximately as 60% copper, 20% nickel and 20% zinc.

Answer 2AgNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + 2Ag (s) Silver Nitrate + Copper → Copper Nitrate + Silver

KCl (aq) + AgNO3 (aq) → AgCl (s) + KNO3 (aq) It is a double displacement and precipitation reaction.

CCl4 will not give the white precipitate of AgCl on heating it with silver nitrate. This is because the chlorine atoms are covalently bonded to carbon in CCl4. To obtain...

Atomic mass of silver (Ag) = 108 u  Since mass of 6.022 × 1023 atoms of silver (Ag) = 108 u  Hence mass of 3.011 × 1023 atoms of silver (Ag)  = 108×3.011×1023/...

Mass of silver = m g  Mass of gold = m /100g  Number of atoms of silver =  Mass/ Atomic mass X NA                        ...
