Edexcel A-Level Chemistry AS 8.14 The Reactions of I Oxides of Group 1 And 2 Elements with Water and Dilute Acid Ii Hydroxides of Group 1 And 2 Elements Questions question 1

[Maximum number: 2]

This question is about some compounds of strontium.

Anhydrous strontium nitrate decomposes at 570∘C570^{\circ} \mathrm{C}.

Sr(NO3)2( s)→SrO( s)+2NO2( g)+1/2O2( g)\mathrm{Sr}\left(\mathrm{NO}_{3}\right)_{2}(\mathrm{~s}) \rightarrow \mathrm{SrO}(\mathrm{~s})+2 \mathrm{NO}_{2}(\mathrm{~g})+1 / 2 \mathrm{O}_{2}(\mathrm{~g})

The solid residue from the decomposition was added to distilled water.

Give one observation for the reaction that takes place, identifying the product of the reaction by name or formula.
