Challenge Problems
Push your limits with challenges.
Question 1
Calculate the theoretical yield of water produced from 10 grams of hydrogen reacted with 20 grams of oxygen (2H₂ + O₂ → 2H₂O).
💡 Hint: Start by converting grams to moles!
Question 2
If 15 grams of sodium reacts with 20 grams of chlorine to produce sodium chloride (2Na + Cl₂ → 2NaCl), identify the limiting reactant and percent yield if 25 grams of NaCl is obtained.
💡 Hint: Calculate theoretical yield first!
