How to Balance Sodium carbonate + Calcium chloride → Sodium chloride + Calcium carbonate |
How to Balance: Na2CO3 + CaCl2 → NaCl + CaCO3
Type of Chemical Reaction: This is a double replacement reaction.
Word Equation: Sodium carbonate + Calcium chloride → Sodium chloride + Calcium carbonate
| Balancing Strategies: This is a double replacement (displacement) reaction. You only need to change one coefficient to balance this equation. The CaCO3 might be a good place to start.
Also note that you could count the CO3 as one thing since you have it on both sides of the chemical equation (in the Na2CO3 and then in the CaCO3). For a complete explanation, watch:
About Balancing Chemical EquationsWhen balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.Only change the coefficients (these are the numbers in front substances).
 Never change the subscripts (the small numbers after elements).
