Question

Which metal react with hot water and liberate hydrogen?

Answer 1

magnesium reacts with water to form magnesiumhydroxide and hydrogen

Answer 2

Answer:

Magnesium is the metal react with hot water and liberate hydrogen.

Explanation:

As per the data given in the question we have to find the metal which liberate hydrogen.

As per the question it is given that metal react with hot water and liberate hydrogen.

Magnesium reacts with hot water to form magnesium hydroxide and hydrogen gas.

Mg+2$H_{2}O$→$Mg(OH)_{2}$+$H_{2}$

Magnesium does not react with cold water, but it reacts with hot water.

In general, acids react with metals to give salt and release hydrogen gas.

Sodium, potassium and calcium readily react with cold water, to produce hydroxides. Magnesium does not react with cold water, but reacts with hot water to produce hydroxide. ZInc and aluminium react only with steam, to produce oxides.

Hence, Magnesium is the metal react with hot water and liberate hydrogen.
