Which of the following is an example of a single replacement reaction?
Understand the Problem
The question is asking for an example of a single replacement reaction among a given set of chemical equations. A single replacement reaction involves one element being replaced by another in a compound.
Answer
2Na + 2H₂O → 2NaOH + H₂
The final answer is 2Na + 2H₂O → 2NaOH + H₂
Answer for screen readers
The final answer is 2Na + 2H₂O → 2NaOH + H₂
More Information
In a single replacement reaction, sodium (Na) displaces hydrogen in water (H₂O), forming sodium hydroxide (NaOH) and hydrogen gas (H₂).
Tips
A common mistake is confusing single replacement reactions with double replacement reactions. In single replacement, only one element is replaced.
