What word or two-word phrase best describes the shape of the fluoroform molecule?
Vlad [161]

Answer : The shape of the fluoroform molecule is Tetrahedral.

Explanation :

First we have to calculate the Hybridization of the molecule by formula,

\text{Number of electrons} = \frac{1}{2}[V+H-C+A]

where,

V = Number of valence shell electron in central atom

H = Number of neighboring monovalent atom

C = charge of cation

A = charge of anion

The central atom in this molecule is Carbon, it has 4 electrons in their valence shell.

The neighboring monovalent atoms are one Hydrogen atom and three Fluorine atom.

There is no charge of cation and anion on the given molecule.

V = 4

H = 1 Hydrogen atom + 3 fluorine atom = 4

C = 0

A = 0

By the above hybridization formula, we get

\text{Number of electrons}= \frac{1}{2}[4+4-0+0] = 4

The number of electron pair = 4

The number of lone pair = 0

The number of electrons is 4, this means that the hybridization is sp^{3} and the geometry of the molecule is Tetrahedral.

The geometry of the molecule is shown below.

How do cells reproduce? ∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵∵
lora16 [44]

Answer:

Cells divide to reproduce. There are two primary methods used, one for somatic cells, which compose the organism’s body, and one for reproductive cells, or gametes.

Scientists call the process of somatic cell division mitosis. Mitosis has six distinct steps in which the cell organizes and copies the DNA in the nucleus. Once copied, each new cell has its own copy of the DNA. The six steps of mitosis are prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Some authorities consider the non-dividing portion of the cell’s lifecycle, known as interphase, to be one of seven steps involved in mitosis; however, interphase cells are not actively dividing.

Sex cells, such as sperm or eggs, must divide differently. Sex cells only possess one-half of the DNA that makes up a new animal. That way, when they combine, the resulting organism gets half of its DNA from its mother and half from its father. Because sex cells only want half of the DNA in each cell, they go through a different division process called meiosis. In meiosis, the cells split a second time, which yields four daughter cells rather than two as with mitosis; however, this provides each daughter cell with 23 chromosomes in contrast to the 46 chromosomes in somatic cells.
