Answer:
NaNO3
Step-by-step explanation:
To determine the limiting reactant, we need to compare the amounts of each reactant present and calculate the amount of product that can be formed from each.
The balanced chemical equation for the reaction between CuCl and NaNO3 is:
2 CuCl + 2 NaNO3 → Cu(NO3)2 + 2 NaCl
Using the molar masses of CuCl and NaNO3, we can convert the given masses to moles:
moles of CuCl = 10 g / 134.45 g/mol = 0.0745 mol
moles of NaNO3 = 6 g / 84.99 g/mol = 0.0706 mol
According to the balanced equation, 2 moles of CuCl react with 2 moles of NaNO3 to produce 1 mole of Cu(NO3)2. Therefore, the theoretical yield of Cu(NO3)2 is:
theoretical yield = 0.0745 mol / 2 mol x (1 mol / 2 mol) = 0.0186 mol
and
theoretical yield = 0.0706 mol / 2 mol x (1 mol / 2 mol) = 0.0177 mol
Since the theoretical yield of Cu(NO3)2 is smaller from NaNO3, NaNO3 is the limiting reactant.
Therefore, NaNO3 is the limiting reactant in this reaction.
