I already have the first two answers I'm just stuck with the last two. A student demonstrates the reaction by mixing 25.00 g of H2SO4 with 25.00 g of CaCO3. a. How many moles of each reactant does the student mix? 2.55 x 10^-1 mol H2SO4 Approx. 2.5 x 10^-1 mol CaCO3 b. Identify the limiting reactant. Explain how you know this. CaCO3 c. Calculate the theoretical mass of the excess reactant. d. Soon after mixing the reactants, the student determines that 33.17 g of CaSO4 was produced by the reaction. Is this a reasonable result? Show calculations to defend your answer.
