Answer:
The consumption of the reactant benzophenone and the production of triphenylmethanol can be detected using their IR absorption spectrum
This reaction is shown on the second uploaded image
The reactant benzophenone is a compound which contains a carbonyl functional group, and the stretching frequency of C=O bond has a high absorption at around 
and frequency band of this wavelength is absent in triphenylmethanol.
in the same vain the product triphenylmethanol is a compound which contains a hydroxyl (OH) functional group, and the stretching frequency of O-H bond has a high absorption at around 
and frequency band of this wavelength is absent in benzophenone.
To use infrared spectroscopy to show that the reaction is occurring is to show the disappearance of the frequency band which indictes the consumption of benzophenone and the appearance frequency band which indictes the formation of triphenylmethanol
Explanation:
Answer:
To make a cloud, air needs only to be cooled to saturation and beyond. ... Usually the water vapor amounts in air are less that this amount. When this is the case, we describe the air as being unsaturated. If we add more vapor to such air, we could reach the maximum for the temperature
Explanation:
Answer:
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. ... Covalent compounds tend to be soft, and have relatively low melting and boiling points.
Answer:
C. An electron has a high probability of being in certain regions.
Explanation:
In the electron cloud model, there are no electron-orbits around the nucleus but a cloud. This cloud has various densities with respect to distance from the nucleus. The most dense region of the cloud (which is the region close to the nucleus) is where electrons has the highest probability of existence.
The model explains that an electron a greater chance of being in the region closer to the nucleus. Thus, an electron has a high probability of being in certain region of the cloud about the central nucleus. And an electrostatic force exists between the nucleus and the electrons.
Answer:
Hence, 15.99 g of solid Aluminum Sulfate should be added in 250 mL of Volumetric flask.
Explanation:
To make 0.187 M of Aluminum Sulfate solution in a 250 mL (0.250 L) Volumetric flask
The molar mass of Aluminum Sulfate = 342.15 g/mol
Using the molarity formula:-
Molarity = Number of moles/Volume of solution in a liter
Number of moles = Given weight/ molar mass
Molarity = (Given weight/ molar mass)/Volume of solution in liter
0.187 M = (Given weight/342.15 g/mol)/0.250 L
Given weight = 15.99 g
