Sure, I can help you solve these questions. Let's go through them one by one:

1. Balance the chemical equation:
To balance the chemical equation, you need to make sure that the number of atoms of each element is equal on both sides of the equation. In this case, we have:

K2Cr2O7 + H2C2O4 + 2H2O → K[Cr(C2O4)2(H2O)2] + CO2 + H2O

To balance it, start by balancing atoms that appear in only one compound on each side. Here's how you can do it step by step:

Start with the carbon atoms:
On the left side, there are two carbon atoms in the dihydrate (2H2C2O4), while on the right side, there is only one carbon atom in (Cr(C2O4)2). To balance the carbon, you need to double the compound on the right side:

K2Cr2O7 + H2C2O4 + 2H2O → K[Cr(C2O4)2(H2O)2] + CO2 + H2O

Now, let's balance the oxygen atoms:
On the left side, there are 2 oxygen atoms in H2C2O4 and 4 oxygen atoms in H2O (2H2O). On the right side, there are 4 oxygen atoms in [Cr(C2O4)2(H2O)2] and 2 oxygen atoms in CO2. To balance the oxygen, you need to add another H2O to the left side:

K2Cr2O7 + H2C2O4 + 2H2O → K[Cr(C2O4)2(H2O)2] + CO2 + H2O + H2O

Finally, let's balance the hydrogen and potassium atoms:
On the left side, there are 2 potassium atoms in K2Cr2O7 and 4 hydrogen atoms in H2C2O4 (2H2C2O4) and 4 hydrogen atoms in H2O (2H2O). On the right side, there are 2 potassium atoms in K[Cr(C2O4)2(H2O)2] and 4 hydrogen atoms in H2O (H2O + H2O). The hydrogen atoms are already balanced, but to balance the potassium atoms, you need to add another K2Cr2O7 to the right side:

2K2Cr2O7 + 3H2C2O4 + 4H2O → 2K[Cr(C2O4)2(H2O)2] + 3CO2 + 6H2O

Therefore, the balanced equation is:
2K2Cr2O7 + 3H2C2O4 + 4H2O → 2K[Cr(C2O4)2(H2O)2] + 3CO2 + 6H2O

2. Calculate the theoretical yield of the reaction:
To calculate the theoretical yield, you need to know the number of moles of the limiting reagent and the stoichiometry of the reaction. The limiting reagent is the reactant that determines the maximum amount of product formed.

In this case, to calculate the theoretical yield, you need the balanced equation and the amount (in moles) of the limiting reagent. Without that information, it's not possible to calculate the theoretical yield.

3. Calculate the theoretical percentage by weight of Cr in the reaction:
To calculate the theoretical percentage by weight of Cr in the reaction, you need to know the molar mass of Cr and the molar mass of the product formed that contains Cr.

In this case, the molar mass of Cr is 52.00 g/mol, and the molar mass of K[Cr(C2O4)2(H2O)2] is (2 x molar mass of K) + (1 x molar mass of Cr) + (2 x molar mass of C2O4) + (2 x molar mass of H2O). Calculate the molar mass of K[Cr(C2O4)2(H2O)2] using these values and convert it into a percentage.

4. Why is quantitative transfer critical in Step 3 of the Procedure:
In Step 3 of the procedure, quantitative transfer is critical because it ensures that all of the reactants are transferred from one container to another without any loss or contamination. This is important because any loss or contamination can result in inaccurate calculations and affect the yield and accuracy of the experiment. Quantitative transfer is essential to obtain reliable and reproducible results.
