The equation C + 2H2O -> CO2 + 2H2

Detailed information about the equation C + 2H₂O -> CO₂ + 2H₂:

• This equation describes the reaction process between burning charcoal (C) and steam (H₂O) to produce carbon dioxide (CO₂) and hydrogen gas (H₂). This is a redox reaction.

Reaction conditions:

• Temperature: Must be high enough for charcoal to react with steam. The suitable temperature is from 700 degrees Celsius upwards.
• Air: Air (mainly oxygen) is needed for the charcoal to burn.

Reaction process:

• First, the charcoal is burned in an air-filled environment to generate heat.
• Steam is then directed through the burning charcoal.
• Steam reacts with charcoal to form CO₂ and H₂.
• CO₂ and H₂ are then recovered and filtered for use in other applications.

Phenomena occurring:

• When charcoal burns, it emits light and heat.
• When steam is directed through charcoal, it creates white-gray smoke.
• The mixture of CO₂ and H₂ produced will be recovered, and the color change can be clearly seen when they are filtered and separated.
