2 is produced by the reaction of 0.4235 mol of CuCl2 according to the following equation: 2CuCl2+4KI→2CuI+4KCl+I22CuCl2+4KI→2CuI+4KCl+I2 .

The question seems to be incomplete as it does not specify what we need to find out from the reaction. However, I can explain how to approach this type of problem.

The balanced chemical equation given is: 2CuCl2 + 4KI → 2CuI + 4KCl + I2

From this equation, we can see that 2 moles of CuCl2 react with 4 moles of KI to produce 2 moles of CuI, 4 moles of KCl, and 1 mole of I2.

If we have 0.4235 moles of CuCl2, we can use the stoichiometry of the reaction to find out how much of the other chemicals will be produced or required.

For example, if we want to find out how many moles of CuI will be produced, we can set up the following ratio:

2 moles CuCl2 / 2 moles CuI = 0.4235 moles CuCl2 / x moles CuI

Solving for x gives us x = 0.4235 moles CuI.

We can do similar calculations for KI, KCl, and I2. However, without a specific question, I can't provide a more detailed answer.
