Answer: The process of heating a crucible to eliminate moisture from a hydrate.
Explanation:
The available choices are:
a. Heating a solvent to aid in the dissolution of a solute.
b. Heating a solid in isolation to remove moisture.
c. Bringing water to a boil for use in a water bath.
d. Heating a crucible to eliminate moisture from a hydrate.
Possible actions that can be done on a hot plate include:
a. Heating a solvent to assist a solute in dissolving.
b. Heating a solid in isolation to dry it.
c. Heating water to boiling for a water bath.
However, it's important to note that using a hot plate for heating a crucible to remove water from a hydrate is not advisable. Silica or ceramic materials are not meant to be heated on a hot plate.
Consequently, the correct procedure is heating a crucible to remove water from a hydrate.
Answer:
The equation formulated by Michaelis-Menten is expressed as
v₀ = Kcat × [E₀] × [S] / (Km + [S])
in which,
Kcat denotes the experimental reaction rate constant; [S] signifies the concentration of the substrate, and
Km represents the Michaelis-Menten constant.

Answer:
Central metal oxidation state: +2
Coordination number: 6
Overall charge: -2
Explanation:
For the ion complex:
Na₂[Cr(NH₃)₂(NCS)₄]
The central metal is chromium, with NH₃ and NCS as the ligands.
NH₃ acts as a neutral ligand, while NCS carries a negative charge.
The entire complex has a charge of:
2Na⁺ + [Cr(NH₃)₂(NCS)₄]⁻² → -2
Since each NCS contributes -1 and there are four NCS, the Cr must possess an oxidation state of +2 to achieve an overall charge of -2.
With 2 NH₃ and 4 NCS attached, the coordination number sums to 2+4 = 6
I trust this clarifies the matter!
What is being removed during the wash is the solvent.
