Answer:
When the two solutions are mixed, a precipitate of calcium carbonate will be formed. Calcium carbonate is the product of the reaction between sodium carbonate and calcium nitrate. The reaction can be represented by the following equation:
2 Na2CO3 + Ca(NO3)2 -> CaCO3 + 2 NaNO3
To calculate the theoretical yield of the reaction, you will need to use the balanced chemical equation to determine the ratio of reactants to products. In this case, the ratio of calcium carbonate to calcium nitrate is 1:1. This means that for every mole of calcium nitrate that reacts, 1 mole of calcium carbonate will be produced.
To calculate the theoretical yield, you will need to first determine the number of moles of each reactant present in the solution. To do this, you can use the following formula:
Moles = (concentration (M) * volume (L)) / 1000 (mL/L)
Plugging in the values for the concentration and volume of each solution, you get:
Sodium carbonate: Moles = (0.38 M * 0.038 L) / 1000 mL/L = 1.47 x 10^-4 moles
Calcium nitrate: Moles = (0.50 M * 0.040 L) / 1000 mL/L = 2.00 x 10^-4 moles
Since the ratio of reactants in the balanced chemical equation is 1:1, the number of moles of calcium carbonate produced will be equal to the number of moles of calcium nitrate that reacts. In this case, the theoretical yield of calcium carbonate will be 2.00 x 10^-4 moles.
To convert this to grams, you will need to know the molar mass of calcium carbonate. The molar mass of calcium carbonate is 100.09 g/mol, so the theoretical yield in grams will be:
Theoretical yield (g) = Moles * Molar mass = (2.00 x 10^-4 moles) * (100.09 g/mol) = 0.002 g
This is the theoretical yield of calcium carbonate that would be produced if the reaction were allowed to go to completion. In practice, the actual yield may be lower due to various factors such as the presence of impurities or the formation of unwanted side products.
