Question

Find the number compounds which are producing the oxides of their metal on thermal decomposition Mg 3 ​ N 2 ​ , Mg ( OH ) 2 ​ , SrCO 3 ​ , Ba ( NO 3 ​ ) 2 ​ , KClO 3 ​

TestHub · Accepted Answer

The compounds that produce metal oxides upon thermal decomposition are Mg(OH)₂, SrCO₃, and Ba(NO₃)₂. Their reactions are:

$M g (O H)_{2} Δ M g O + H_{2} O$

$S r C O_{3} Δ S r O + C O_{2}$

$2 B a (N O_{3})_{2} Δ 2 B a O + 4 N O_{2} + O_{2}$

Mg₃N₂ is stable to heat, and KClO₃ decomposes into KCl and O₂ rather than an oxide. Thus, the total number of such compounds is 3.
