Question

explain the reaction of different metal with hot water cold water and steam give one example with proper balance chemical equation name two metals which do not react with any form of water​

Answer 1

Answer:

Sodium reacts explosively with cold water.

On the other hand, metals such as iron do not react with cold water or hot water. However, it reacts with steam to give their respective oxides and hydrogen gas. Thus, metals react with water to form metal oxides and hydrogen gas.

Answer 2

SOLUTION:

Here is the reaction of metal with water.

• (i) The reaction of metal with cold water.

$\boxed{\red{2Na(s)+2H_{2}O(l) \longrightarrow 2NaOH(aq)+H_{2}(g)}}$

Here,

Na = Sodium

H₂O = Water (cold)

NaOH = Sodium hydroxide

H₂ = Hydrogen gas

• (ii) The reaction of metal with hot water.

$\boxed{\pink{Mg(s)+2H_{2}O(l) \longrightarrow Mg(OH)_{2}(aq)+H_{2}(g) \uparrow}}$

Here,

Mg = Magnesium

H₂O = Water (hot)

Mg(OH)₂ = Magnesium hydroxide

H₂ = Hydrogen gas

Now,

• (iii) The reaction of metal with steam,

$\boxed{\blue{Fe(s)+H_{2}O(g) \longrightarrow FeO(s) + H_{2}(g) \uparrow}}$

Here,

Fe = Iron(II) or ferrous

H₂O = steam

FeO = Iron (II) oxide

H₂ = hydorgen

Another,

$\boxed{\blue{2Fe(s)+3H_{2}O(g) \longrightarrow Fe_{2}O_{3}(s) + 3H_{2}(g) \uparrow}}$

So, here

Fe = Iron(III) or ferric

H₂O = steam

Fe₂O₃ = Iron(III) oxide

H₂ = hydorgen

.

$\boxed{\green{3Fe(s)+4H_{2}O(l) \longrightarrow Fe_{3}O_{4}(s)+4H_{2}(g) \uparrow}}$

Here, Fe₃O₄ = Iron (II) or (III) oxide

And,

The increasing order of reactivity of these metals is Fe < Mg < Na.

Gold and Siler do not react with any form of water.
