How Many Moles Of CO2 Are Produced When 2.0 Mol Of CH4 Are Burned In A Car Engine?
Understanding the Chemical Reaction
The combustion of methane (CH4) is a common process in car engines, where methane reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is:
CH4 + 2O2 → CO2 + 2H2O
In this equation, 1 mole of methane reacts with 2 moles of oxygen to produce 1 mole of carbon dioxide and 2 moles of water.
Calculating the Number of Moles of CO2 Produced
To calculate the number of moles of CO2 produced when 2.0 mol of CH4 are burned, we need to use the stoichiometry of the reaction. The balanced equation shows that 1 mole of CH4 produces 1 mole of CO2. Therefore, if 2.0 mol of CH4 are burned, the number of moles of CO2 produced will be equal to the number of moles of CH4 burned.
Applying the Stoichiometry of the Reaction
Using the stoichiometry of the reaction, we can calculate the number of moles of CO2 produced as follows:
Number of moles of CO2 produced = Number of moles of CH4 burned = 2.0 mol
Therefore, when 2.0 mol of CH4 are burned in a car engine, 2.0 mol of CO2 are produced.
Understanding the Importance of Stoichiometry
Stoichiometry is a crucial concept in chemistry that helps us understand the quantitative relationships between reactants and products in chemical reactions. In this case, the stoichiometry of the reaction allows us to calculate the number of moles of CO2 produced when 2.0 mol of CH4 are burned.
Real-World Applications of Stoichiometry
Stoichiometry has numerous real-world applications in fields such as chemistry, biology, and engineering. For example, stoichiometry is used to calculate the amount of reactants required for a chemical reaction, the amount of products formed, and the amount of byproducts produced.
Conclusion
In conclusion, when 2.0 mol of CH4 are burned in a car engine, 2.0 mol of CO2 are produced. This calculation is based on the stoichiometry of the reaction, which shows that 1 mole of CH4 produces 1 mole of CO2. Understanding the stoichiometry of chemical reactions is essential in chemistry and has numerous real-world applications.
