Question

NO2 , SrO , KI , wich one produces basic solution when added to water . '

Ni , Ne , Na wich one is the least reactive

C2H6 CH4 C5H12 wich one turns liquid in room temperature

Answer 1

1. $\mathrm{NO}_2$, $\mathrm{SrO}$, $\mathrm{KI}$, which one produces basic solution when added to water.

2. Ni, Ne, Na which one is the least reactive

3. $\mathrm{C}_2\mathrm{H}_6\mathrm{CH}_4\mathrm{C}_5\mathrm{H}_{12}$ which one turns liquid at room temperature

1. $\mathrm{SrO} + \mathrm{H}_2\mathrm{O} \rightarrow \mathrm{Sr}(\mathrm{OH})_2$

2. Ne

3. $\mathrm{C}_5\mathrm{H}_{12}$
