__________ is formed when hydrogen is oxidised during combustion. what one word completes the sentence?
Water is the one word that completes the sentence: "Water is formed when hydrogen is oxidised during combustion".
Quick Scoop
When hydrogen gas reacts with oxygen during combustion, it undergoes an oxidation process where hydrogen atoms combine with oxygen atoms to form water (H2OH_2OH2O). This chemical reaction is typically expressed as:
2H2+O2→2H2O2H_2+O_2\rightarrow 2H_2O2H2+O2→2H2O
Key Characteristics of Hydrogen Combustion
- Product: The primary and most common product of complete hydrogen oxidation is water, often emitted as water vapor.
- Energy Release: This reaction is highly exothermic, meaning it releases a significant amount of heat and light energy.
- Oxidation State: During this process, hydrogen is oxidised (loses electrons or gains oxygen) while oxygen acts as the oxidizing agent.
Common Combustion Products
While hydrogen specifically forms water, different fuels produce various oxides depending on their composition:
Fuel Component| Oxidation Product| Common State
---|---|---
Hydrogen (HHH)| Water (H2OH_2OH2O) 1| Vapor or Liquid
Carbon (CCC)| Carbon Dioxide (CO2CO_2CO2) 3| Gas
Sulfur (SSS)| Sulfur Dioxide (SO2SO_2SO2) 3| Gas
