Question
Enter the correct coefficients in each blank to make this equation balanced. (Enter a 1 if it should be blank)
K(ClO3) + Ca(OH)2 → Ca(ClO3)2 + K(OH)
Solution
To balance the equation K(ClO3) + Ca(OH)2 → Ca(ClO3)2 + K(OH), you need to ensure that the number of atoms of each element is the same on both sides of the equation.
Step 1: Identify the number of atoms for each element on both sides of the equation.
On the left side, you have:
- 1 K atom
- 1 Cl atom
- 3 O atoms
- 1 Ca atom
- 2 O atoms
- 2 H atoms
On the right side, you have:
- 1 Ca atom
- 2 Cl atoms
- 6 O atoms
- 1 K atom
- 1 O atom
- 1 H atom
Step 2: Balance the atoms that appear in complex molecules first.
Start with the Cl and O atoms in ClO3. There are 2 Cl atoms and 6 O atoms on the right side in Ca(ClO3)2, so you need 2 K(ClO3) on the left side.
Now the equation is: 2K(ClO3) + Ca(OH)2 → Ca(ClO3)2 + K(OH)
Step 3: Balance the remaining atoms.
Now, balance the K, O, and H atoms in K(OH). There are 2 K atoms on the left side, so you need 2 K(OH) on the right side.
The balanced equation is: 2K(ClO3) + Ca(OH)2 → Ca(ClO3)2 + 2K(OH)
