Question

exaplin activity of action of steam on a metal and diagram​

Answer 1

GiveN :-

• To explain the action of steam on a metal with diagram .

SolutioN :-

The metals located at the top of the reactivity series react easily with cold water or hot water like Potasium , Sodium , etc .

But Magnesium reacts very slowly with water in liquid form. However it reacts vigoursly with steam .

• The word equation is :-

$\boxed{\pink{\sf Magnesium + Water \to Magnesium\ oxide + Hydrogen }}$

• The chemical equation is :-

$\boxed{\pink{ \sf Mg\gray{ (s)} + H_2O\gray{( g)} \to MgO\gray{ (s)} + H_2 \gray{(g) } }}$

The metals which react with steam form Solid metal oxide and evolve Hydrogen gas .The digram of apparatus is in attachment.
