Vedclass · Answer

(D) Metals react with water to form metal oxides and hydrogen gas. $1$. Calcium reacts with cold water. $2$. Magnesium does not react with cold water but reacts with hot water. $3$. Iron $(Fe)$ does not react with cold or hot water. However,it reacts with steam to form iron oxide $(Fe_3O_4)$ and hydrogen gas $(H_2)$. The chemical equation is: $3Fe(s) + 4H_2O(g) \rightarrow Fe_3O_4(s) + 4H_2(g)$. Therefore,Iron is the correct answer.

Which metal does not react with cold or hot water,but reacts with steam to produce $H_2$ gas?
