MP Board · Class 10 · Science · Chemical Reactions and EquationsWhat type of reaction is represented by the equation: 2H₂ + O₂ → 2H₂O?
Step 1: Identify the reactants and product
The equation shows hydrogen gas (H₂) reacting with oxygen gas (O₂) to form water (H₂O).
Step 2: Classify the reaction
When two or more substances combine to form a single product, the reaction is called a combination (or synthesis) reaction.
Step 3: Verify with definition
A combination reaction is defined as:
Two or more reactants combine to produce one product. The given equation fits this definition perfectly.
Conclusion
Therefore, the reaction 2H₂ + O₂ → 2H₂O is a combination reaction.
