Question

How are the following prepared from hydrogen? illustrate with the equation. give the condition of the reaction

• Water

Answer 1

Preparation of water

Condition:

• Pressure - 1 atm
• Temperature - room temperature

Reaction:

• Hydrogen burns in the air mean it is reacting with oxygen at 1 atm pressure and at room temperature to give water.

$\underset{\mathrm{Hydrogen}\mathrm{gas}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygeb}\mathrm{gas}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

• Hydrogen is a combustible gas.
• It burns in the air, producing water
• When a large quantity of hydrogen burns in the air, it leads to an explosion. this is because hydrogen combines with oxygen violently.
