Answer:
A, T, C y G, son las "letras" del código del ADN; representan los compuestos químicos adenina (A), timina (T), citosina (C) y guanina (G), respectivamente, que constituyen las bases de nucleótidos del ADN. ...El código genético es el conjunto de reglas que define cómo se traduce una secuencia de nucleótidos en el ARNm a una secuencia de aminoácidos en una proteína
The theory assumes that collisions between gas molecules and the walls of a container are perfectly elastic, gas particles do not have any volume, and there are no repulsive or attractive forces between molecules .
Answer:
<em>The polyoxometalates initially abstract the hydrogen of the alkane to form the alkyl radical and the reduced polyoxometalates. The reduced polyoxometalates subsequently react with nitric acid to produce the oxidized form and nitrogen dioxide.</em>

Atoms form a new substance by bonding with different atoms.
For example, hydrogen atoms and oxygen atoms bond to form H2O as per this equation:
2H2 + O2 ---> 2 H2O
To understand how to hydrogen and oxygen atoms form water you can write that as:
2 H - H + O - O ---> 2 H - O - H
Each hypen represent a chemical bond.
What is happening is that the H - H atoms and the O - O separate and bond with different atoms: H bonds to O which in turn bonds to other H.
Also, you have to know that chemical bonds are the result of interaction between the electrons of the valence shell of electrons of each atom. This is, valence electrons from O interact with valence electrons of H to form the bond H - O.
The interaction may be in different ways depending on the properties of the atoms: the kind of bonds known are metallic, ionic and covalent.
