Worked Solution & Example Answer:Sodium reacts with fluorine to form sodium fluoride - OCR Gateway - GCSE Chemistry - Question 12 - 2021 - Paper 2
Step 1
What is the correctly balanced symbol equation for this reaction?
Answer
To correctly balance the reaction between sodium (Na) and fluorine (F₂), we need to consider how sodium and fluorine combine to form sodium fluoride (NaF).
- Sodium reacts with fluorine gas (F₂). Each molecule of fluorine (F₂) contains two atoms of fluorine.
- When sodium (Na) and fluorine (F₂) react, it takes two sodium atoms to combine with one fluorine molecule to produce two units of sodium fluoride.
Thus, the balanced equation is:
Therefore, the correct answer is D.
