Answer:
C
Explanation:
an index fossil is a fossil from a very short-lived, geographically widespread species known to exist during a specific interval of geological time.
Tetrahedral molecular geometry is the only one that can exist for sp3 hybridized center atoms.
<h3>Which chemical contains an sp3 hybridized central atom?</h3>
- An atom that is bound and a nonponding pair of electrons are the two different kinds of electron domains.All bonded atoms count as one electron domain on the center atom, regardless of whether they are connected by a single, double, or triple bond.
- There are five fundamental geometries for electron domains. The core oxygen atom in the water molecule has six valence electrons.The 6 valence electrons of oxygen are arranged in hybridized sp3 orbitals, resulting in 2 paired and 2 free electrons.
- One s orbital and three p orbitals combine to generate four sp3 orbitals, each of which has a 25% s character and a 75% p character. This process is known as sp3 hybridization.
- An example of CO2 can be used to illustrate how lone pairs of electrons make up an SP3 hybrid orbital.We are only able to count bond pairs or lone bonds.
