What is the amount of silver oxide formed when 11.04g of silver carbonate is strongly heated ? Write the balanced chemical equation for the reaction. `Ag_(2)CO_(3) rarr 2AgO + CO_(2)`.

Explanation

`"Molar mass of " Ag_(2) CO_(3)} = {(2xx" atomic mass of .Ag."),(+"atomic mass of .C."),(+3xx"atomic mass of .O."):}`
`= 2 xx 108 + 12 + 3xx16`
= 276 u
Molar mass of AgO`= {("atomic mass of .Ag."),(+"atomic mass of .O."):}`
`= 108 + 16 = 124g mol^(-1)`
When silver carbonate is heated, carbon dioxide leaves as gas and silver oxide remains as a residue.
According to the equation,
`{:("One mole of "),(Ag_(2)CO_(3) " leaves"):}}= { ("2 mol of AgO"),("as residue"):}`
`276g ` of `Ag_(2)O = 124g ` of AgO
11.04 of `Ag_(2) O = ( 124)/( 276) xx 11.04g ` of AgO
= 4.96g
