What characteristic frequencies in the infrared spectrum of your estradiol product will you look for to determine whether the ca
gladu [14]

Answer:

Strong broad peak around 3200-3600 cm-1 should be present

Strong peak around around 1700 cm-1 should be absent

Explanation:

Infrared spectroscopy is an analytical technique which is used for molecular structure characterization by identifying the functional groups present in a given molecule based on the absorption wavelength (or wavenumber).

In an IR spectrum the carbonyl group is associated with the C=O stretch which occurs as a strong peak around around 1700 cm-1. For alcohol the -corresponding O-H stretching frequency occurs as a strong broad peak between 3200-3600 cm-1.

Therefore, in the case of estradiol the presence a strong broad peak in the 3200-3600 cm-1 and the absence of the peak at around 1700 cm-1. would suggest that the transformation is complete.

The same force is applied separately to two objects, A and B. B has twice the mass of A. What happens?
Alexeev081 [22]

Answer:

B's acceleration is half that of A

Explanation:

The force equation is;

Force = mass × acceleration

According to Newton's second law of motion, which explains the relationship between acceleration and mass of an object, an inverse relationship exists between the mass and the acceleration. For the same amount of force, an increase in mass (m) means a constant decrease in acceleration (a) of the object. In other words, if the mass of an object increases by two times, the acceleration will decrease by two times.

In this case involving objects A and B which has the same amount of force applied, object B has TWICE the mass of A. Using Newton's second law, this means that object B's ACCELERATION WILL BE HALF OF THAT OF OBJECT A.

Need some help anyoneee like bad bad
crimeas [40]

Answer:

D. CF₄

Explanation:

The compound with this molecular geometry is Carbon tetrafluoride (CF₄)

Carbon tetrafluoride (CF₄) also known as Tetrafluoromethane, is known to be the simplest perfluorocarbon. The compound, tetrafluoromethane  is the hydrocarbon methane has been perfluorinated. It useful as a refrigerant but known to be a greenhouse gas. Due to the nature of the carbon-flourine bond, it has very high bonding strength. Its bonds are known to be the strongest single bonds in organic chemistry.

Option D is the correct answer.
