Following steps are involved in this reaction,
Nitration: Nitration of benzene yield nitrobenzene.
Reduction: Reduction of Nitrobenzene yield Aniline.
Diazotization: Diazonium alt of benzene is formed from aniline.
At last diazonium salt is reacted with CuCl to yield chlorobenzene.
Answer:
Electrical conductivity
Explanation:
Electrical conductivity - A material's ability to conduct electricity
The capacity to do work is said to be energy. It is a quantitative property and conserved quantity. It can exist in different forms such mechanical energy, sound energy, chemical energy etc. According to law of conservation of energy, energy can neither be created nor be destroyed implies there is no loss of energy occurs during any process or any reaction only conversion of energy takes place.
Temperature and pressure are not forms of energy, they are physical properties.
Hence, first option (1) is the correct answer i.e. chemical, mechanical, electromagnetic are three forms of energy.
The parameter pH is a measure of the substance's acidity or basicity. It is quantitatively equal to the negative logarithm of the concentration of H+ ions. So, the lower the pH, the more acidic the substance, Otherwise, the higher the pH the more basic the substance. The pH range runs from 1 to 14, with 7 being neutral.
So, if we are asked to distinguish which of those have the lowest pH, we have to know the moles of H+ ions. Since all of them have a concentration of 0.1 M, concentration is not a factor. Thus, we just have to identify the strongest acid among the list. That is easy to answer because you only have to remember 7 strong acid occurring in nature: HCl, H₂SO₄, HNO₃, HClO₄, HClO₃, HBr, and HI. Since only HNO₃ is included in the list among the choices, the answer would be letter D.
D) The average mass of all isotopes of the element
