Answer Details
When steam is passed over red-hot carbon, the substances produced are hydrogen and carbon (II) oxide.
The reaction that occurs is known as the water-gas shift reaction and is represented by the chemical equation:
C(s) + H2O(g) → CO(g) + H2(g)
In this reaction, steam (H2O) reacts with carbon (C) in the presence of heat to produce carbon (II) oxide (CO) and hydrogen gas (H2). The carbon (II) oxide is formed because the carbon combines with only one of the oxygen atoms from the steam to form CO, while the other oxygen atom combines with hydrogen to form water (H2O).
Therefore, the substances produced by passing steam over red-hot carbon are hydrogen gas and carbon (II) oxide.
