Challenge Problems
Push your limits with advanced challenges
If 5.00 g of aluminum reacts with excess chlorine gas to form aluminum chloride (AlCl₃), calculate the theoretical yield of AlCl₃. Assume complete reaction.
💡 Hint: Start with the molar mass, then find how much AlCl₃ can be produced from the given Al.
Calculate the limiting reagent and percent yield if 30.0 g of ammonium nitrate (NH₄NO₃) reacts with 40.0 g of sodium hydroxide (NaOH) to produce sodium nitrate (NaNO₃) and water. Write the balanced equation first.
💡 Hint: Divide the masses by their molar masses, then compare ratios to find the limiting reagent.
