Final answer:
To balance the equation PbCl₂ + K₂CO₃ → PbCO₃ + KCl, you need to ensure that the number of atoms of each element is the same on both sides of the equation. The balanced equation is PbCl₂ + 2K₂CO₃ → PbCO₃ + 2KCl.
Step-by-step explanation:
To balance the equation PbCl₂ + K₂CO₃ → PbCO₃ + KCl, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go step by step:
First, we count the atoms of each element on the left side of the equation:
Pb: 1
Cl: 2
K: 2
C: 1
O: 3
Now, let's count the atoms of each element on the right side of the equation:
Pb: 1
Cl: 1
K: 1
C: 1
O: 3
To balance the number of Cl atoms, we need a coefficient of 2 in front of KCl. To balance the number of K atoms, we also need a coefficient of 2 in front of K₂CO₃. The balanced equation is:
PbCl₂ + 2K₂CO₃ → PbCO₃ + 2KCl
