A 50.0 mL volume of 0.50 M of X is mixed with 50.0 mL of 0.20 M of Y. a. Considering the value of K in the 100.0 mL of solution, determine the concentration of XY(aq)

0.1M

Explanation:

So, we are given the following data or parameters which is going to help in solving this particular Question:

=> There are two compounds/elements compound/element X and compound/element Y.

(NB: We are not giving the atomicity)

=> "A 50.0 mL volume of 0.50 M of X is mixed with 50.0 mL of 0.20 M of Y."

Thus, X + Y > XY(aq).

The first thing to do here is to determine the number of moles of each reactants that is X and Y.

The number of moles of X = 0.50M × 50 × 10^-3 L = 0.025 moles.

The number of moles of Y = 0.20M × 50 × 10^-3 L = 0.01 moles.

Hence, we have that 0.025 moles of X reacted with 0.01 moles of Y to give XY.

The limiting reagent/reactant is Y.

Therefore, 0.01 mole of Y × (1 mole XY/1 mole of Y) = 0.01 moles of XY.

Thus, the number of moles of XY is 0.01 mole.

Hence, we have that 0.025 moles of X reacted with 0.01 moles of Y to give 0.01 moles of XY.

So, the molarity or the concentration of XY(aq) = 0.01/(100 × 10^-3 ) = 0.1M

increased stability in the completion of fluorine's outer shell.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
