![### Balancing Chemical Equations
**Instruction:**
Fill in the coefficients (include a 1 where appropriate or a single space) to balance this chemical equation:
\[ \_\_\_\_\_\_\_ \text{K} + \_\_\_\_\_\_\_ \text{H}_2\text{O} \rightarrow \_\_\_\_\_\_\_ \text{H}_2 + \_\_\_\_\_\_\_ \text{KOH} \]
**Spaces for Coefficients:**
- **Blank 1:**
- **Blank 2:**
- **Blank 3:**
- **Blank 4:**
In a balanced chemical equation, the number of atoms of each element on the reactant side must equal the number of atoms of the same element on the product side.
To balance this equation, identify the coefficients needed for each compound and molecule to ensure that both sides of the equation have the same number of atoms for each element involved.
**Detailed Steps:**
1. **Identify the Number of Atoms of Each Element on Both Sides:**
- Reactants:
- Potassium (K): 1 atom
- Water (H₂O): 2 Hydrogen (H) atoms and 1 Oxygen (O) atom
- Products:
- Hydrogen Gas (H₂): 2 Hydrogen (H) atoms
- Potassium Hydroxide (KOH): 1 Potassium (K) atom, 1 Oxygen (O) atom, and 1 Hydrogen (H) atom
2. **Balance Potassium (K):**
- There is 1 atom of K on both sides initially.
3. **Balance Hydrogen (H):**
- There are 2 Hydrogen atoms in H₂ and 1 Hydrogen atom in KOH on the product side. So, you'll need a total of 3 Hydrogen atoms.
- Adjust the amount of H₂O to provide the necessary H atoms.
4. **Balance Oxygen (O):**
- There is 1 Oxygen atom in H₂O and the same amount appears in KOH.
**Balanced Chemical Equation:**
\[ 2 \text{K} + 2 \text{H}_2\text{O} \rightarrow \text{H}_2 + 2 \text{KOH} \]
**Filled Coefficients:**
- **Blank 1](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4876e6df-aedd-42df-ad3e-25ec29d5d98f%2F66a07a3b-4491-4726-b062-1bb3bb45ca5a%2F5yyr6v_processed.jpeg&w=3840&q=75)
