Question

What is action of water on Na, Mg, and Fe? Give related chemical equations.​

Answer 1

Action of Na on water :-

$\rm \implies \: Na + H_2O \longrightarrow NaOH + H_2(g)$

Balanced eq.

$\rm \implies \: { \green{2}}Na + { \green{2}}H_2O \longrightarrow { \green{2}}NaOH + H_2(g)$

$\rm \implies \: Sodium + Water \longrightarrow Sodium \: hydroxide + Hydrogen</p><p>$

Action of Mg on water :-

$\rm \implies \: Mg + H_2O \longrightarrow MgO + H_2(g)$

Balanced eq.

$\rm \implies \: { \green{2}}Mg + { \green{2}}H_2O \longrightarrow { \green{2}}MgO +{ \green{2}} H_2(g)$

$\rm \implies \: Magnesium + water \longrightarrow Magnesium oxide + Hydrogen</u></p><p><u>[tex] \rm \implies \: Magnesium + water \longrightarrow Magnesium oxide + Hydrogen$

Action of Fe on water :-

$\rm \implies \: Fe + H_2O \longrightarrow FeO + H_2(g)</p><p>$

Balanced eq.

$\rm \implies \: { \green{2}}Fe + { \green{2}}H_2O \longrightarrow{ \green{2}} FeO + { \green{2}}H_2(g)</u></p><p><u>[tex] \rm \implies \: { \green{2}}Fe + { \green{2}}H_2O \longrightarrow{ \green{2}} FeO + { \green{2}}H_2(g)$

$\rm \implies \: Iron(II) + water \longrightarrow Iron \: oxide + hydrogen$
