Balance the following chemical equation.
![**Balancing Chemical Equations - Example Problem**
In order to balance the following chemical equation, you need to determine the correct coefficients that will make the number of atoms for each element the same on both sides of the equation.
Unbalanced equation:
\[ \text{___} \, \text{C}_2\text{H}_6 + \text{___} \, \text{O}_2 \rightarrow \text{___} \, \text{CO}_2 + \text{___} \, \text{H}_2\text{O} \]
Place the correct numbers in the following blanks:
- Blank 1: [Place the coefficient for \( \text{C}_2\text{H}_6 \) here]
- Blank 2: [Place the coefficient for \( \text{O}_2 \) here]
- Blank 3: [Place the coefficient for \( \text{CO}_2 \) here]
- Blank 4: [Place the coefficient for \( \text{H}_2\text{O} \) here]
**Steps to balance the equation:**
1. Identify the number of atoms of each element in the reactants and products.
2. Balance the number of atoms for each element one element at a time by adding appropriate coefficients.
**Example Solution** (Do not include exact values here):
1. Balance the carbon (C) atoms.
2. Balance the hydrogen (H) atoms.
3. Balance the oxygen (O) atoms, being mindful to adjust both water (\( \text{H}_2\text{O} \)) and carbon dioxide (\( \text{CO}_2 \)) coefficients as needed.
4. Ensure all coefficients are in the lowest possible ratio.
**Example of a balanced chemical equation:**
\[ x \, \text{C}_2\text{H}_6 + y \, \text{O}_2 \rightarrow z \, \text{CO}_2 + w \, \text{H}_2\text{O} \]
*Note: \( x, y, z, \) and \( w \) are integers that will make the equation balanced. Fill in the respective blanks with these integers once you find them by following the steps listed above.*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd523066f-b053-453c-adec-7257125c89c0%2F97e56704-bf81-49b2-bf15-cc5d1bf045ca%2Fbk5kl5k_processed.jpeg&w=3840&q=75)
