In the synthesis reaction you mentioned, two atoms of sodium (Na) combine with one molecule of chlorine gas (Cl₂) to produce sodium chloride (NaCl). The balanced chemical equation for this reaction is:
\[ 2 \text{Na} + \text{Cl}_2 \rightarrow 2 \text{NaCl} \]
From this equation, we can see that:
- 2 moles of Na reacts with 1 molecule of Cl₂.
- This produces 2 moles of NaCl.
If you're asking how many molecules of NaCl are produced from a specific amount of Na or Cl₂, please provide that amount, and I'll be happy to help you calculate it!
