When washing soda is heated :
Correct answer: D. Water vapour is released
- A. Only CO2 is released
- B. CO & CO2 are released
- C. Only CO is released
- D. Water vapour is released
Explanation
When washing soda is heated, it loses all water of crystallisation and becomes anhydrous sodium carbonate. The correct answer is that only water vapors are released. The other options are incorrect because they do not accurately reflect the chemical changes that occur when heating washing soda.

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.

A salt 'X' on heating liberates one coloured gas and another colourless gas. Both the gases are paramagnetic. The salt 'X' may be:
CsBr3 contains:
Na + Al2O3 →(high temperature) X (CO2 in water)→ Y ; compound Y is :
Be and Al exhibit many properties which are similar. But the two elements differ in:
A solid compound 'X' on heating gives CO2 gas and a residue. The residue mixed with water forms 'Y'. On passing an excess of CO2 through 'Y' in water, a clear solution, 'Z' is obtained. On boiling 'Z', compound 'X' is reformed. The compound 'X' is:
