What is the significance of a gene?Immersive Reader

Chemistry
1 answer:
Ilia_Sergeevich [38]3 years ago
4 0

Explanation:

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. These small differences contribute to each person’s unique physical features.

What is the formula for copper(ii) phosphate? capitalization and punctuation count!?
iVinArrow [24]
Hello!

The formula for Copper (II) Phosphate is

Cu₃(PO₄)₂

To know how to write this formula we go from left to right. First, Copper (II). It means that the formula has the Cu⁺² ion. Now, Phosphate means that the compound has the PO₄⁻³ ion. Now we combine this two ions, giving to each one the coefficient with the number of the electric charge of the other (e.g. to Cu⁺² we'll give the charge of PO₄⁻³ which is 3 and the result will be Cu₃⁺²). 

The combination gives us the result Cu₃(PO₄)₂

Which of the following molecules or ions is polar? (20 POINTS)
taurus [48]

<u>For NO3- molecule(fig.1)</u>

1.  Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NO3 are polar.

2. In the geometry of the molecule  bond polarities cancel out each other (since it is a vector) so NO3- ion molecule is non polar

3.   Nitrate (NO3-)ion  geometry would be trigonal planar

<u>For CCl4 molecule(fig.2)</u>

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in CCl4 are polar.

2. It is a completely symmetrical molecule.

3.Carbon is the centre of CCl4 have four covalent bonds and it has no lone pairs. They are all equidistant the C-Cl bond polarities cancel out. So CCl4 molecule is non polar

<u>For NH3 molecule(fig.3)</u>

1. Bonds are created between elements with different electronegativity, most bonds would be polar. Bonds in NH3 molecule are polar.

2.  it has a pyramidal structure.

3. the individual N-H bond dipoles don't cancel out. This dipole moment for the molecule indicates that NH3 is a polar molecule

<u>For SF6 molecule(fig.4)</u>

1.F is more electronegative than S. So the bonds are polar.

2. The symmetry of the molecule is  symmetrical so that the dipole moments of bonds cancel correspond so the molecule is non-polar.

3. it has octahedral structure

How many atoms are in 1.4 mol of phosphorus trifluoride (PF3)?
harkovskaia [24]
NA = 6.022*10^23
number of atoms = number of moles * avogadros number
number of atoms = <span>6.022*10^23 * 1.4 moles * 4 atoms / molecules of PCl3
Number of atoms = 3.37*10^23 atoms.</span>
