A scientific theory is a principle that can be falsified. The theory has to make strong statements about evidence. If the statements aren't strong, then the theory fits any evidence, and is unfalsifiable.

What are its electron-pair and molecular geometries? What is the hybridization of the nitrogen atom? What orbitals on and overla
jok3333 [9.3K]

Answer:

Electron-pair geometry: tetrahedral

Molecular geometry: trigonal pyramidal

Hybridization: sp³

sp³ - 4 p

Explanation:

There is some info missing. I think this is the original question.

<em>For NBr₃, What are its electron-pair and molecular geometries? What is the hybridization of the nitrogen atom? What orbitals on N and Br overlap to form bonds between these elements?</em>

<em>The N-Br bonds are formed by the overlap of the  ___ hybrid orbitals on nitrogen with ___ orbitals on Br.</em>

<em />

Nitrogen is a central atom surrounded by 4 electron domains. According to VESPR, the corresponding electron-pair geometry is tetrahedral.

Of these 4 electron domains, 3 represent covalent bonds with Br and 1 lone pair. According to VESPR, the corresponding molecular geometry is trigonal pyramidal.

In the nitrogen atom, 1 s orbital and 3 p orbitals hybridize to form 4 sp³ orbitals for each of the electron domains.

The N-Br bonds are formed by the overlap of the sp³ hybrid orbitals on nitrogen with 4p orbitals on Br.

Calculate the molar mass of aspirin, C9H8O4
Vladimir79 [104]
Add up all the molar masses of the elements multiplied by the number of atoms each.

Molar mass of carbon = 12.01g
Molar mass of hydrogen = 1.01g
Molar mass of oxygen = 16g

9(12.01) + 8(1.01) + 4(16)
Molar mass of aspirin = 180.17g
