Hey there!
K₂Te + Fe(HCO₃)₂ → KHCO₃ + Fe + Te
Start by balancing HCO₃ since it's a polyatomic ion.
Two on the left, one on the right. Add a coefficient of 2 in front of KHCO₃.
K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te
Balance K .
Two on the left, two on the right. Already balanced.
Balance Te.
One on the left, one on the right. Already balanced.
Balance Fe.
One on the left, one on the right. Already balanced.
Our final balanced equation:
K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te
Hope this helps!
