Question

what happens when Sodium is heated with cold water ? give equations also ​

Answer 1

Answer:

Na + H2O --> NaOH + H2

When sodium is heated with water, it forms a colourless liquid called sodium hydroxide, and water. the reaction is exothermic, meaning it releases energy

Answer 2

Answer:

When sodium is dropped in cold water, it reacts explosively and burns with a golden-yellow flame. The reaction is exothermic and vigorous. It forms sodium hydroxide with the liberation of hydrogen gas. The reaction is so violent and exothermic that the hydrogen which is evolved immediately catches fire.

Equation: -

2Na(s)+2H2O ➡ 2NaOH(aq)+H2(g)
