Question

why does sodium metal catches fire when placed in water ? Write equation in support of your answer. ​

Answer 1

Answer:

This reaction is highly exothermic evolving a lot of heat which is sufficient enough to melt sodium due to its low melting point. Sodium moves in water as the dihydrogen gas formed below the waterline pushes sodium. If sodium is trapped in the container the increasing temperature could induce dihydrogen to catch fire.

why does sodium metal catches fire when placed in water ? Write equation in support of your answer

$\huge\tt\underline{answer}$

Sodium (Na) is metal which is extremely reactive which reacts with water and produces hydrogen gas.H2 gas catches fire as it creates intense heat from the reaction.

$\tt\underline\pink{equation}$:

$2Na(s) + 2H _{2}O(1)⇉2 NaOH(aq) + H_{2}$
