Because God wanted it that way....

Explanation:

We know that carbonates generally decompose to give metal oxides and carbon dioxide...

#MCO_3(s)stackrel(Delta)rarrMO(s) + CO_2(g)uarr#

Nitrates CAN undergo an equivalent reaction...but three products are often observed...the #"metal oxide"#.. #"nitrogen(IV) oxide"#, and #"dioxygen..."#

#M(NO_3)_2(s)stackrel(Delta)rarrMO(s) + 2NO_2(g)uarr+1/2O_2(g)uarr#
