a) Metal in the powdered form reacts very slowly with the boiling water, but it decomposes steam.
Name the metal.
b) Write a balanced equation for the reaction of the named metal with (i) boiling water (ii) steam
b) Mg + 2H2O → Mg(OH)2 + H2
Mg + H2O →MgO + H2
[Music] hello dear student i am sunita nair from dido learning let's answer this question a metal in the powdered form reacts very slowly with the boiling water but it decomposes steam name the metal b write the balanced equation for the reaction of the named metal with boiling water and with steam so the metal in question is magnesium magnesium belongs to the second group of the periodic table which is the group of the alkaline earth metals magnesium bill is mg now let's write the reaction now how does it react with hot water so if you drop a piece of magnesium into boiling water it reacts with the water to form the hydroxide of magnesium that is mg oh two plus hydrogen gas is also given out so you can see the bubbles of hydrogen in the water so let's balance this equation we have 2 h2o right so this is the reaction of magnesium with boiling water now let's next let's write the reaction of magnesium with steam now how does magnesium react with steam if magnesium is burnt in the presence of steam it burns fairly vigorously to form the oxide of magnesium that is mgo and again hydrogen gases evolved so this is with when burnt in steam so these were the two reactions of the metal in a powdered form when you drop some powdered magnesium in boiling water it forms the hydroxide of magnesium and hydrogen gas is given out if you light the powder in steam it decomposes steam into hydrogen and oxygen i hope this answers your question do drop in a comment if you have a doubt visit our channel because we have many questions answered for you and do subscribe to alido channel for updates as well thank you
