Please help with #2 and #3
Vaselesa [24]

Answer:

2. V_2=17L

3. V=82.9L

Explanation:

Hello there!

2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:

\frac{V_2}{T_2}=\frac{V_1}{T_1}

Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:

V_2=\frac{V_1T_2}{T_1}

Therefore, we plug in the given data to obtain:

V_2=\frac{18.2L(22+273)K}{(45+273)K} \\\\V_2=17L

3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:

V=\frac{nRT}{P}

Therefore, we plug in the data to obtain:

V=\frac{3.7mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=82.9L

Best regards!

Determine what the spin state of each complex will be using the spectrochemical series along with your chemical intuition. Pleas
seropon [69]

Answer:

A) high spin complex

B) low spin complex

Explanation:

A) VCI3(H20)3 is a high spin complex and this is because the complex has a weak field ligands all . this weak field ligands makes it impossible for pairing to take place

B) Fe(NH3)23 is a low spin complex and this is because the complex is made up of strong field ligands, this strong field ligands makes it possible for paring to take place

note : Ligands in which its donor atoms are ; Nitrogen,phosphorous or carbon are considered strong ligands

The process by which the movement of internal bonds converts one type of what organic compound into another is
nevsk [136]

Answer: It's is called Reaarrangement

Explanation:

Rearrangement is a chemic reaction in which an atom or group of atoms bond migrate from one carbon atom to another. The movement involves two adjacent atoms and move over a large distance. It is important in functional group transformation.

Reaarrangement can be classified based on the atom or group of atoms it migrate.

Nucleophilic rearrangement which involves the migration of atoms with electron pairs.

Electrophilic migration involved the migration of atom or groups without electron pair.

Free radical involves the atom or group of atoms moving with a lone pair of electron.
