Challenge Problems
Push your limits with advanced challenges
In the reaction 4H₂ + O₂ → 4H₂O, you start with 10 grams of H₂ and 15 grams of O₂. Determine the limiting reactant and the theoretical yield of water.
💡 Hint: Convert the masses to moles, apply the ratios, and then ascertain product yields.
For the reaction C₆H₁₂ + 9O₂ → 6CO₂ + 6H₂O, if you start with 80 grams of C₆H₁₂ and excess oxygen, calculate the amount of water produced.
💡 Hint: Understand the ratios produced per balanced equation and use them to calculate the final product.
