The reaction of an Arrhenius acid with an Arrhenius base produces water and <span>A) a salt</span>
Explanation:
Water is a polar solvent as the hydrogen and oxygen atom has large difference in their electronegativities.
Oxygen atom is highly electronegative as compared to hydrogen atom therefore, it pulls the electrons of hydrogen atom closer towards itself.
As a result, two poles will create forming a partial positive charge on the hydrogen atom and partial negative charge on the oxygen atom.
Thus, we can conclude that high electronegativity difference between oxygen and hydrogen is the cause of polarity in water molecules.
It obtains a neutral pH (7). The combination of a strong acid and a strong base results in a neutral pH. The pH of HCl is about 1, and the pH of NaOH is 14.
DescriptionA chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.
Explanation:
When an electron absorbs the light it jumps from its lower energy state towards the higher energy state. This known as absorption.
When an electron come backs from higher energy to lower energy level energy is released emitted out in the form of light. This is known as emission.
1) n = 3 to n = 5 ,This transition will be absorption.
2) n = 1 to n = 3 ,This transition will be absorption
3) n = 3 to n = 2 ,This transition will be emission.
4) n = 2 to n = 1 ,This transition will be emission.
