Water gas is a mixture of C
Answers
Water gas is a mixture of carbon monoxide and hydrogen produced from synthesis gas. Synthesis gas is a useful product, but requires careful handling due to its flammability and the risk of carbon monoxide poisoning. The water-gas shift reaction can be used to reduce the carbon monoxide while producing additional hydrogen, resulting in water gas.
Synthesis gas is made by passing steam over a red-hot carbon fuel such as coke:
H

O+C→H

+CO;(ΔH=+131kJ/mol)
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.
O

+C→CO

(ΔH=−393kJ/mol)
Theoretically, to make 6 L of water gas, 5 L of air is required.
Or, alternatively, to prevent contamination with nitrogen, energy can be provided by using pure oxygen to burn carbon into carbon monoxide.

+2C→2CO (ΔH=−221kJ/mol)
In this case 1 L of oxygen will create 5.3 L of pure water gas.
Answer:
hydrogen and oxygen atoms
two hydrogen and one oxygen
like the name suggests ,h2o also said h two o
or hydrogen two atoms and one oxygen atom
