Answer:
0.086
Explanation:
The formula for calculating the fraction of a covalent bond can be expressed as:
= exp (-0.25ΔE²)
![= exp[-0.25(E_{Al}-E_{p})^2]---(1)](https://tex.z-dn.net/?f=%3D%20exp%5B-0.25%28E_%7BAl%7D-E_%7Bp%7D%29%5E2%5D---%281%29)
from the equation above;
= the electronegativity of aluminum
= electronegativity of phosphorus
Using the data from periodic table figures;
= 1.5
= 2.1
∴
fraction of the covalent = exp[-0.25(1.5 - 2.1)²]
fraction of the covalent = exp(-0.09)
fraction of the covalent = 0.914
Now, the fraction of ionic bond will be = 1 - the fraction of covalent bond
= 1 - 0.914
∴
the fraction of bond that is ionic = 0.086
Answer:
If temperature increases, the number of collisions per second also increase because particles absorb energy.

The pH of an aqueous solution with a hydrogen ion concentration of [H+]=1. 2×10^−8 m is 7.92.
The entire form of pH is potential of Hydrogen. pH is called the poor logarithm of H+ ion attention. hence the that means of the name pH is explained because the energy of hydrogen. pH describes the concentration of the hydrogen ions in a solution and it's miles the indicator of acidity or basicity.
pH is an important amount that reflects the chemical conditions of an answer. The pH can manage the provision of vitamins, organic features, microbial activity, and the conduct of chemical substances.
pH stands for capacity hydrogen and it's used to explain the acidity or alkalinity of a substance. The pH scale is measured from 1 to fourteen. 7 is impartial and the lower the quantity, the extra acidic and the higher, the greater alkaline.
explaination,
[H+]=1. 2×10^−8 m
log[h+] = 1. 2×10^−8 m
= 8 - log (1.2)
= 8 - 0.079
PH = 7.921
