What is water gas and how it is prepared in chemistry?
Water-gas A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O → CO + H2.
What is water gas how it is produced?
Water gas is a synthesis gas, containing carbon monoxide and hydrogen. It is a useful product but requires careful handling due to its flammability and the risk of carbon monoxide poisoning. The gas is made by passing steam over a red-hot carbon fuel such as coke: H2O+C→H2+CO.
What is water gas How is it prepared Class 11?
In the preparation of water gas, superheated steam is passed over white-hot coke and then the mixture of water gas obtained. In the above reaction on reactant side carbon (coal) and water (steam) reacted at high temperature and on product side carbon monoxide and hydrogen gas mixture is formed.
Where is water gas used?
(1) It is used in the production of Ammonia by producing hydrogen. (2) It is used in welding and glass making. (3) It is used for several organic compound synthesis in industries like the production of several hydrocarbons. (4) Water gas helps in the removal of Carbon dioxide from fuel cells.
Which gas is mixed with water?
Water-gas A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O # CO + H2.
Why is Class 11 poisonous?
Carbon monoxide is poisonous for humans because it can easily form a complex with human hemoglobin. Thus, in this state, hemoglobin does not further bind to oxygen. Thus, the person suffers from lack of oxygen or hypoxia and dies.
Is syngas a biofuel?
Syngas produced from biomass gasification can be used as feedstock for the production of a wide range of biofuels such as methanol, ethanol, hydrocarbon fuels (gasoline, kerosene, diesel, DME), hydrogen, or synthetic natural gas (SNG).
How is carbon monoxide and hydrogen gas prepared?
A mixture of carbon monoxide and hydrogen gas is commonly known as water gas. [CO + H2]® water gas It is used as a fuel. PREPARATION: It is prepared by passing steam over red hot coke. C + H2O ®CO + H2
How is water gas prepared in the VA?

How much Air do you need to make water gas?
The reaction is endothermic, so the fuel must be continually re-heated to keep the reaction going. In order to do this, an air stream, which alternates with the vapor stream, is introduced for the combustion of carbon to take place. Theoretically, to make 6 L of water gas, 5 L of air is required.
How is hydrogen gas obtained from natural gas?
BY THERMAL DECOMPOSITION OF METHANE: When natural gas is heated up to 1000oC in the presence of catalyst, hydrogen gas is obtained. CH4®C + 2H2 BY COKE AND STEAM PROCESS:
