Compound resistant to thermal decomposition is:
Correct answer: D. Na2CO3
- A. Li2CO3
- B. NaNO3
- C. Ba(NO3)2
- D. Na2CO3
- E. Non
Explanation
Na₂CO₃ is highly stable and resists decomposition even at high temperatures (above 1600°C). It remains intact under typical heating conditions.Ba(NO₃)₂, NaNO₃, and Li₂CO₃ decompose at relatively low to moderate temperatures:Ba(NO₃)₂ decomposes around 500°C.NaNO₃ decomposes around 380°C.Li₂CO₃ decomposes around 600°C

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
