Working

How to balance it, step by step

  1. Count the atoms of each element on both sides, as written.
  2. Start with the biggest formula, Cl₂: put 1 in front of it.
  3. Cl: 2 on the left. Put 2 in front of NaCl.
  4. Na: 2 on the right. Put 2 in front of Na.
  5. Check: Na 2 = 2, Cl 2 = 2. Balanced.
The reaction

What happens

It is a combination reaction: two or more substances join to form a single product. Sodium burns in chlorine to form sodium chloride, an ionic compound made of Na⁺ and Cl⁻ ions.

Questions

Sodium and chlorine: quick answers

What is the balanced equation for sodium and chlorine?

2 Na(s) + Cl₂(g) → 2 NaCl(s). The coefficients are 2, 1 and 2. Each side then has 2 Na and 2 Cl.

What type of reaction is sodium and chlorine?

It is a combination reaction: two or more substances join to form a single product. Sodium burns in chlorine to form sodium chloride, an ionic compound made of Na⁺ and Cl⁻ ions.

How do you balance Na + Cl₂ → NaCl?

Start with the biggest formula, Cl₂: put 1 in front of it. Cl: 2 on the left. Put 2 in front of NaCl. Na: 2 on the right. Put 2 in front of Na. Never change a subscript, because that would change the substance.
