Q30 / 160 · TS EAMCET 2014 · Chemistry

Which one of the following elements reacts with steam?

  • A
    C
  • B
    $\mathrm{Ge}$
  • C
    Si
  • Correct answer
    D
    Sn

Solution

C, Si and Ge do not react with water while Sn reacts with steam and forms $\mathrm{SnO}_2$ and $\mathrm{H}_2$. $\mathrm{Sn}(\mathrm{s})+2 \mathrm{H}_2 \mathrm{O}(g) \stackrel{\Delta}{\longrightarrow} \mathrm{SnO}_2(g)+2 \mathrm{H}_2(g)$

Hence, the correct answer is option: 'D'.
