At what temperature does uranium hexafluoride have a density of 0.5820 g/L at 0.5073 atm?
Svet_ta [14]

Answer:

4204 K

Explanation:

Step 1: Data

<em>Given data</em>

  • Density of uranium hexafluoride (ρ): 0.5820 g/L
  • Pressure of uranium hexafluoride (P): 0.5073 atm

<em>Required data</em>

  • Universal gas constant (R): 0.08206 atm.L/mol.K
  • Molar mass of uranium hexafluoride (M): 352.02 g/mol

Step 2: Calculate the temperature of the gas

We will use the following expression derived from the ideal gas equation.

P × M = ρ × R × T

T = P × M/ρ × R

T = 0.5073 atm × (352.02 g/mol)/(0.5820 g/L) × (0.08206 atm.L/mol.K)

T = 4204 K

Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonatio
Over [174]

Answer:

Most substituted alkene is produced as a major product

Explanation:

  • Dehydration of 3-methyl-2-butanol proceeds through E1 mechanism to form alkenes.
  • Most substituted alkene is produced as major product because of presence of highest number of hyperconjugative hydrogen atoms corresponding to the produced double bond (Saytzeff product).
  • Here, a H-shift also occurs in one of the intermediate step during dehydration to produce more stable tertiary carbocation.
  • Reaction mechanism has been shown below.

What is the number of the group that has the most reactive nonmetals (give number and letter- Ex 1A, 2A, etc.)?​
Kryger [21]

Answer:

Group 7A

Explanation:

The group 7A elements consists of the most reactive non-metals on the periodic table.

This group is known as the group of halogens. They consist of element fluorine, chlorine, bromine, iodine and astatine.

  • The elements in this group have the highest electronegativity values.
  • They have 7 valence electrons and requires just one electron to complete their octets.
  • This way, they are highly reactive in their search for that single electron.
