Synthesis Reaction Chemistry Example 2

Follow the full solution, then compare it with the other examples linked below.

Example 2

medium
Predict the product and write the balanced equation for the synthesis reaction between sodium and chlorine gas.

Solution

  1. 1
    Na is a Group 1 metal (forms Na+\text{Na}^+). Cl is a Group 17 nonmetal (forms Cl−\text{Cl}^-).
  2. 2
    The product is sodium chloride: NaCl.
  3. 3
    Balanced: 2Na+Cl2→2NaCl2\text{Na} + \text{Cl}_2 \rightarrow 2\text{NaCl}. Check: Na 2=2, Cl 2=2. ✓

Answer

2Na+Cl2→2NaCl2\text{Na} + \text{Cl}_2 \rightarrow 2\text{NaCl}
In synthesis reactions between a metal and a nonmetal, the product is an ionic compound. Use the ion charges to predict the formula of the product.
