**Task: Balancing Chemical Equations**

Write a balanced chemical equation for the reaction that occurs when acetone, \( \text{CH}_3\text{COCH}_3(l) \), is combusted in air.

**Instructions:**

Express your answer as a balanced chemical equation including phases.

**Equation Provided:**

\[ \text{CH}_3\text{COCH}_3(l) + 4\text{O}_2(g) \rightarrow 3\text{CO}_2(g) + 3\text{H}_2\text{O}(g) \]

**Feedback:**

- **Status:** Incorrect
- **Prompt:** Try Again
- **Attempts Remaining:** 2

**Note:**

Ensure that the number of atoms for each element on the reactant side matches the number of atoms on the product side. Adjust coefficients accordingly to balance the equation properly.
