Which of the following statements is true for strontium or its compounds?
Correct answer: D. Sr(OH)2 is dehydrated to the oxide on being heated
- A. Sr does not burn in air
- B. Sr does not react with steam
- C. SrCO3 decomposes at a lower temperature than CaCO3
- D. Sr(OH)2 is dehydrated to the oxide on being heated
Explanation
The correct answer is Option D. Strontium hydroxide (Sr(OH)2) indeed undergoes dehydration to form strontium oxide (SrO) when heated. The other options are incorrect as strontium does burn in air, reacts with steam to form strontium hydroxide, and strontium carbonate decomposes at a higher temperature compared to calcium carbonate.

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.
