Answer : The correct expression for equilibrium constant will be, ![K=[O_2]^5](https://tex.z-dn.net/?f=K%3D%5BO_2%5D%5E5)
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of 
will be,
Therefore, the correct expression for equilibrium constant will be,
I think that it is helium, but not 100% sure
The number of hydrogen atoms is twice the number of oxygen atoms in ribose.
<h3>What is Ribose?</h3>
This is a sugar and a component of the ribonucleotides from which RNA is built. It has the formula C₅H₁₀O₅.
Ribose is a carbohydrate with the formula C₅H₁₀O₅. This molecule is a pentose monosaccharide which has a linear form 
. The hydroxyl groups lie on the same side in the form of Fischer Projections.
The number of hydrogen atoms is double the number of oxygen atoms. The ribose sugar is found in the RNA.
It is the genetic material which is found in some organisms that carry information from one generation to another.

Answer:
The coordination sphere of a complex consists of <u><em>the central metal ion and the ligands bonded to it.</em></u>
Explanation:
The Coordination Compounds are sets of a central metal ion attached to a group of molecules or ions that surround it. They are also called metal complexes or simply complexes. Then they are compounds that have a central atom surrounded by a group of molecules or ions, the latter called ligands.
The central atom must have empty orbitals capable of accepting pairs of electrons, with the transition metals being the ones with the greatest tendency. Because of this, they can act as Lewis acids (electron pair acceptors). The ligands have unshared electron pairs, then acting as Lewis bases (electron pair donors).
When forming a complex, it is said that the ligands coordinate to the metal and the central metal and the ligands attached to it constitute the coordination sphere of the complex.
Finally, <u><em>the coordination sphere of a complex consists of the central metal ion and the ligands bonded to it.</em></u>
