Final answer:
The balanced equation for the synthesis of calcium carbonate is CaO + CO2 -> CaCO3. The reaction yield is 100% because the mass of the reactants is equal to the mass of the products. To determine the limiting reactant and calculate the theoretical yield, convert the mass of each reactant to moles and use the mole ratios from the balanced equation.
Step-by-step explanation:
A) The balanced equation for the synthesis of calcium carbonate is:
CaO + CO2 → CaCO3
B) To calculate the reaction yield, the mass of the reactants and products must be considered. In this case, the mass of CO2 is 4.4 g and the mass of CaO is 5.6 g. These masses add up to 10 g, which is equal to the mass of the reactant, CaCO3. Since the mass of the reactants is equal to the mass of the products, the reaction yield is 100%.
C) To determine the limiting reactant, convert the mass of each reactant to moles using their molar masses. Then, use the mole ratios from the balanced equation to find the limiting reactant. Finally, calculate the theoretical yield based on the limiting reactant. The percent yield is determined by dividing the actual yield by the theoretical yield and multiplying by 100.
