Nettet15. nov. 2024 · Hear this out loudPauseThe limiting reactant and the excess reactant are important in a chemical reaction. The key difference between limiting reactant and excess reactant is that the limiting reactant can limit the amount of final product produced, whereas excess reactant has no effect on the amount of final product.

NettetStep 1: Write a balanced equation and identify known and unknown. Step 2: Calculate n (known). Compare mole of O2 required to actual. •Compare mole of O2 required to actual. •Because the actual mole is less than the required mole, there is not enough O2. Therefore O2 is the limiting reactant. •Therefore Mg is the excess reactant. NettetStep 2: Calculate the moles of each reactant. Moles = Mass ÷ Ar. Moles Na = 9.2/23 = 0.40. Moles S = 8.0/32 = 0.25. Step 3: Compare the moles. To react completely 0.40 moles of Na requires 0.20 moles of S and since there are 0.25 moles of S, then S is in excess. Na is therefore the limiting reactant.
