Explanation:
It is given that r = 0.283 nm. As 1 nm = .
Hence, 0.283 nm =
- Formula for coulombic energy is as follows.
where, e = C
=
=
- As 1 eV =
So, 1 J =
Hence, U =
= 8.9 eV
- Also, 1 J =
= kJ/mol
Therefore, U = kJ/mol
=
Answer:
Most similar ----- Lithium
Least similar ---- Nitrogen
Explanation:
Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as .
The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound with the oxygen
The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17 to form an with oxygen.
Answer:
a. C₆H₅OH(aq)
Explanation:
The reaction of phenol with water is shown below as:-
According to Arrhenius, The specie which furnish protons in solution is known as acid. In the above reaction, phenol, acts as an acid by contributing a H⁺ ion to create H₃O⁺ in the chemical equation.
<u>a. C₆H₅OH(aq) is the answer</u>
A central silicon atom is bonded to two chlorine atoms and two methyl groups
Explanation:
Enantiomers are chiral molecules that are mirror images of each other but cannot be superimposed on each other. In this case, a silicon atom, bonded to two chlorine atoms and two methyl groups, when its bonds are rotated, can appear like mirror images of the previous molecule.
