$N a (s) + H_{2} O (l) \to N a O H (a q) + \frac{1}{2} H_{2} (a q) ↑ ⏐ ⏐ ⏐$ $Na(s) + H_2O(l) rarr NaOH(aq) + 1/2H_2(aq)uarr$

Sodium metal is a powerful enuff reductant to reduce the water molecule to give dihydrogen gas. The is clearly an example of a redox equation:

$N a \to N a^{+} + e^{-}$ $Na rarr Na^(+) +e^-$ $(i)$ $(i)$

$H_{2} O + e^{-} \to \frac{1}{2} H_{2} (g) ↑ ⏐ ⏐ ⏐ + H O^{-}$ $H_2O + e^(-) rarr 1/2H_2(g)uarr +HO^-$ $(i i)$ $(ii)$

Overall........................ $(i) + (i i) :$ $(i) + (ii):$

$N a (s) + H_{2} (l) \to \frac{1}{2} H_{2} (g) + N a^{+}^{-} O H (a q)$ $Na(s) + H_2(l) rarr 1/2H_2(g) + Na^(+)""^(-)OH(aq)$

What is the balanced equation for this reaction: Na+H2O→NaOH+H2Na + H_2O -> NaOH + H_2. What is the submicroscopic view of the equation?
