**Question:**

Write the chemical formula for cobalt(II) hydrogen carbonate.

---

**Explanation:**

To determine the chemical formula:

1. **Cobalt(II) Ion:** Cobalt in the +2 oxidation state is represented as Co²⁺.
2. **Hydrogen Carbonate Ion:** The hydrogen carbonate (bicarbonate) ion is represented as HCO₃⁻.

Since the charges must balance, one cobalt ion will combine with two hydrogen carbonate ions to form a neutral compound.

**Chemical Formula:** Co(HCO₃)₂

This formula reflects that one cobalt ion binds with two hydrogen carbonate ions to create cobalt(II) hydrogen carbonate.
