Answer:
The two atoms will contribute and share two electrons each in a double covalent bond, to form a molecule of the element.
Explanation:
Following the rule which says that an octet structure in the valence electrons shell of an atom, when two atoms of an element with the electronic configuration 1s²2s²2p⁴ comeclose to each other, they will share there electrons in covalent bonding to form a molecule, and thus attain stability by achieving an octet structure.
An atom of the element with electronic configuration 1s²2s²2p⁴, has 6 valence electrons and thus, needs two more electrons in order to achieve an octet. This is achieved by sharing two electrons with another atom of the same element which contributes two electrons as well to form a double covalent bond and a molecule of the element. Therefore, each atom would then have an octet structure in their valence shells.

True for DNA only:
- Contains the nucleotide deoxythymidine monophosphate.
True for RNA only:
- Is involved in the process of protein synthesis in the cytoplasm of the cells in the liver.
True for both DNA and RNA:
- Contains the base adenine.
- Is synthesized by a process that involves base pairing.
True neither for DNA nor RNA:
- Is an inherently directional molecule, with an NN-terminus on one end and a CC-terminus on the other end.
- Occurs only in single-stranded form.
Some facts:
DNA known as Deoxyribonucleic acid acts as the genetic material of all living organism except for some viruses. It stores the genetic information of an organic life form. DNA has deoxyribose sugar and is a double stranded helix.
RNA or Ribonucleic acid can be genetic or non genetic material. It functions in transferring the genetic information stored in DNA during protein synthesis and in control of gene expression.RNA also have enzyme activity in the form ribozyme and it is the genetic material of some viruses and virioids.

The tire pressure is the sum of gauge pressure and the standard pressure of atmospheric pressure
We know that the standard air pressure of surrounding = 101.325 kPa
The given gauge pressure = 413 kPascal
So the tire pressure = 101.325 kPa + 413 = 514.325 K Pa
We can also convert the given pascals to atmosphere or Torr or mmHg or bar
