Answer:

A metallic carbonate which on heating forms its respective metal is Silver Carbonate.

Explanation:

Silver Carbonate:

• The symbol of silver carbonate is Ag2CO3.

• Silver carbonate has no smell and its color is pale golden.

• This is a highly unstable substance.
• By heating silver carbonate it creates silver metal (Ag), carbon di oxide (CO2) and Oxygen (O2). While other metallic carbonate substances don't break into metal, they create metal oxide.

                   So, this is a special characteristic of silver nitrate. We can express the equation as, Ag2CO3(s) + Heat = 2Ag(s)+CO2(g)+ $\frac{1}{2}$O2(g).

•   The molecular weight of silver carbonate is 276 gm/mole and the molecular weight of silver is 108 gm/mole.

                  When 1 mole  Ag2CO3 burns, it creates 2×108 gm = 216 gm silver.
