**Problem Statement:**

How much heat (in kJ) is released when 170 grams of CH₄ is burned with 2000 grams of O₂? If the answer is exothermic, be sure your answer has the correct sign!

**Chemical Equation:**

CH₄ + 2O₂ → CO + 2H₂O   ΔH = -803 kJ/mol

OR

C H₄ + 2 O₂ → CO + 2H₂O  ΔH = -803 kJ/mol

**Instructions:**

- **Hint:** Determine the limiting reagent.
- **Note:** Do not type units with your answer.
- **Precision:** Type your answer to three significant figures.

**Additional Information:**

If this question is on an exam, report your answer on your scrap paper to the proper number of significant figures but still type three significant figures online.
