what is a limiting reagent of the reaction CuSO4 and Pb(NO3)2

That depends upon how much you have of each compound. There would be an equal number of moles of each reagent in a stoichiometric reaction. The limiting reagent is the one with the least number of moles available.

To determine the limiting reagent in a reaction, we need to compare the amount of each reactant in relation to the stoichiometry or molar ratio of the balanced equation.

The balanced equation for the reaction between CuSO4 and Pb(NO3)2 is:

CuSO4 + Pb(NO3)2 → PbSO4 + Cu(NO3)2

From the balanced equation, we can see that the molar ratio between CuSO4 and Pb(NO3)2 is 1:1.

To determine the limiting reagent, we need to know the quantities (in moles or mass) of CuSO4 and Pb(NO3)2 involved in the reaction.

Let's assume we have 2 moles of CuSO4 and 3 moles of Pb(NO3)2.

Using the molar ratio from the balanced equation, we can see that for every 1 mole of CuSO4, we need 1 mole of Pb(NO3)2.

Thus, 2 moles of CuSO4 will require 2 moles of Pb(NO3)2.

Since we have 3 moles of Pb(NO3)2, and only 2 moles of CuSO4 are needed, Pb(NO3)2 is in excess, and CuSO4 is the limiting reagent.

Therefore, CuSO4 is the limiting reagent in the reaction between CuSO4 and Pb(NO3)2.

To determine the limiting reagent in a chemical reaction, you need to compare the stoichiometry of the reactants (the balanced chemical equation) with the amounts given for each reactant. In this case, let's consider the reaction between CuSO4 (copper(II) sulfate) and Pb(NO3)2 (lead(II) nitrate).

The balanced chemical equation for the reaction is:

CuSO4 + Pb(NO3)2 → Cu(NO3)2 + PbSO4

First, let's determine the molar ratios between the reactants and products by looking at the coefficients in the balanced equation. The coefficient of CuSO4 is 1, and the coefficient of Pb(NO3)2 is also 1.

Now, compare the given amounts of the reactants and convert them to moles.

Let's say you have a certain amount of CuSO4 and Pb(NO3)2 in grams:

- Convert the grams of CuSO4 to moles by dividing the mass by the molar mass of CuSO4.
- Convert the grams of Pb(NO3)2 to moles by dividing the mass by the molar mass of Pb(NO3)2.

Now, use the mole ratios from the balanced equation to determine which reactant is the limiting reagent. The reactant that produces the least amount of product is the limiting reagent.

Calculate the moles of product that can be formed for each reactant by multiplying the moles of the limiting reagent by the corresponding stoichiometric ratio from the balanced equation.

Compare the calculated moles of product for each reactant. The reactant that produces the lower amount of product is the limiting reagent.

Therefore, to find the limiting reagent, compare the calculated moles of product from each reactant. The reactant that produces the lesser amount of product is the limiting reagent in the reaction.
