Challenge Problems
Push your limits with challenges.
Question 1
In a reaction with 5.00 g of A (molar mass = 10.00 g/mol) and 12.00 g of B (molar mass = 24.00 g/mol), if the balanced equation is 2A + 3B -> C, calculate the limiting reagent.
💡 Hint: Calculate moles and use the mole ratio to assess which reagent will be used first.
Question 2
For the reaction 2Cu + O_2 -> 2CuO, if you have 100 g Cu and 32 g O_2, determine the limiting reagent.
💡 Hint: Check how many moles of each reactant are needed based on the balanced equation.
