Question

When 1 mol of pure $A g_{2} C O_{3}$ is strongly heated, calculate the weight of residue obtained in gm.

Open in App

Solution

$A g C O_{3} Δ \to A g_{2} O + C O_{2} ↑ A g_{2} O Δ \to 2 A g + \frac{1}{2} O_{2} ↑$
Residue is metallic Ag. $1 m o l A g_{2} C O_{3} = 2 m o l A g$ $= 216 g A g$
