Hydrogen

The promoter used in the Bosch process is:

• iron oxide

• chromic oxide

• molybdenum

• copper

Water gas is a mixture of:

• CO + N₂

• CO₂ + N₂

• CO + H₂

• CO₂ + H₂

The unreacted CO in Bosch Process is removed using:

• ammoniacal cuprous chloride

• water under pressure

• caustic potash

• caustic soda

This reaction takes place in diffused sunlight:

• formation of water

• formation of ammonia

• formation of hydrogen chloride

• formation of hydrogen sulphide

Haber Process is the manufacture of:

• hydrogen

• hydrogen sulphide

• hydrogen chloride

• ammonia

An example of a good reducing agent is:

• hydrogen

• oxygen

• nitrogen

• chlorine

Hydrogen reacts with oxygen to form water in the ratio:

• 1:2

• 2:1

• 1:8

• 8:1

Hydrogen reacts with molten sulphur to form:

• HSO3

• H₂SO₄

• H₂SO₃

• H₂S

The promoter used in the Haber process is:

• ferric oxide

• chromic oxide

• molybdenum

• finely divided iron

1. C+ H₂O--> CO + H₂

2. CO + H₂O --> CO₂ + 2H₂

_{These reactions are respectively:}

• exothermic and endothermic

• endothermic

• exothermic

• endothermic and exothermic
