Which one of the following elements reacts with steam?

Which one of the following elements reacts with steam?

Options

  1. AC
  2. BGe\mathrm{Ge}
  3. CSi
  4. DSn

Correct answer

D. Sn

Step-by-step solution

C, Si and Ge do not react with water while Sn reacts with steam and forms SnO2\mathrm{SnO}_2 and H2\mathrm{H}_2. Sn(s)+2H2O(g)⟶ΔSnO2(g)+2H2(g)\mathrm{Sn}(\mathrm{s})+2 \mathrm{H}_2 \mathrm{O}(g) \stackrel{\Delta}{\longrightarrow} \mathrm{SnO}_2(g)+2 \mathrm{H}_2(g)
