Answer 1

C+2H2->CH4
CH4+2O2->CO2+2H2O

Answer 2

Chemical Equations for the Given Scheme

The given scheme represents a series of chemical reactions involving the elements H₂, O₂, and C. Let's break down the reactions step by step.

1. Formation of Water (H₂O) from Hydrogen (H₂) and Oxygen (O₂): - The balanced chemical equation for the formation of water from hydrogen and oxygen is: ``` 2H₂ + O₂ → 2H₂O ``` - This reaction represents the combination of hydrogen and oxygen to form water.

2. Formation of Carbon Dioxide (CO₂) from Carbon (C) and Oxygen (O₂): - The balanced chemical equation for the formation of carbon dioxide from carbon and oxygen is: ``` C + O₂ → CO₂ ``` - This reaction represents the combustion of carbon in the presence of oxygen to form carbon dioxide.

3. Overall Reaction: - Combining the above two reactions, the overall reaction can be represented as: ``` 2H₂ + O₂ + C → 2H₂O + CO₂ ``` - This equation represents the overall chemical reaction involving the elements H₂, O₂, and C, resulting in the formation of water (H₂O) and carbon dioxide (CO₂).

Conclusion

The chemical equations for the given scheme involving the elements H₂, O₂, and C have been derived. The reactions demonstrate the formation of water and carbon dioxide through the combination of these elements. If you have any further questions or need additional explanations, feel free to ask!
