The purpose of washing the organic product that contains water with anhydrous calcium chloride is to remove water from the organic product, thereby, increasing its purity. Calcium chloride is known to be one of the most effective drying agents together with sodium sulfate and magnesium sulfate. It is especially used for hydrocarbons. It is an inorganic salt that readily takes up the water from the organic product.

Anhydrous solids are the crystallized crystals when the hydrate form of the compound undergoes crystallization. Hence, when an anhydrous salt is placed in an aqueous environment, it will absorb water in order to be a hydrate once again. Thus, anhydrous calcium chloride is used to absorb the water to separate it from the organic product.

The enzyme Y catalyzes the elementary reaction
lions [1.4K]

Answer:

0.7μM = 0.6 μM = 0.5 μM > 0.4 μM > 0.3 μM > 0.2 μM

Explanation:

An enzyme solution is saturated when all the active sites of the enzyme molecule are full.  When an enzyme solution is saturated, the reaction is occurring at the maximum rate.

From the given information, an enzyme concentration of 1.0 μM Y can convert a maximum of 0.5 μM AB to the products A and B per second means that a 1.0 M Y solution is saturated when an AB concentration of 0.5 M or greater is present.

The addition of more substrate to a solution that contains the enzyme required  for its catalysis will generally increase the rate of the reaction. However, if the enzyme is saturated with substrate, the addition of more substrate will have no effect on the rate of reaction.

<em>Therefore the reaction rates at substrate concentrations of 0.7μM, 0.6 μM, and 0.5 μM are equal. But the reaction rate at substrate concentrations of  0.2 μM is lower than at 0.3 μM, 0.3 μM is lower than 0.4 μM and 0.4 μM is lower than 0.5 μM, 0.6 μM and 0.7 μM.</em>

Determine the electron-group arrangement, molecular shape, and ideal bond angle(s) for each of the following:
Sunny_sXe [5.5K]

The electron group arrangement of CH₂Cl₂ is penta-atomic. The molecular shape is tetrahedral, and the bond angle is 109.5°.

<h3>What is the bond angle?</h3>

The bond angle is the angle between the atoms of the compound. The bond angle is defined in degree. The bond length is also there. It is the distance between the nuclei of the two atoms.

The bond angle of CH₂Cl₂ is 109.5°. According to the VSEPR theory, as the structure will be tetrahedral.

Thus, the penta-atomic configuration of CH2Cl2's electrons. Tetrahedral is the molecular shape, the bond angle is 109.5°.
