.what mulliken proposed on electronegativity? |
| Answer» ROBERT S. Mulliken proposedthat the arithmetic mean of the first ionization energy (EI1) and the electron affinity (Eea) should be a measure of the tendency of an ATOM to attract ELECTRONS. ... Inserting the appropriate data into Equation 1 gives a Mulliken electronegativity VALUE for fluorine of 1004.6 kJ/mol. | |

What me a short introduction on water pollution plz......jaldi dena or dekar ke aswers mat dena |
|
Answer» Answered it in own words. May be some faults will arise but given my bestWater Pollution:-___________________Water pollution is one of the main cause for water degredation. As water is essential part of life. There is no Living organism who can live without water. Besides this water is universal solvent which increases the importance of water. HOWEVER human beings are polluting the water DAY-by-day. They forgot that water one of the most valuable thing on earth and for their survival water is necessary. If they will not consume water, they will not be able to survive. In order to extend life years, one has to save water and has make EFFORTS to stop water from being polluted..Because of lack of knowledge AMONG people about CONSERVATION of water resources and it's importance, water is being polluted in many ways like people throw garbage in water, they make the water dirty by throwing domesticated supplies,etc. Even water is being polluted by industries as they releases harmful industrial affluents in water. This creates an drastic effect on human's health, if they will consume degraded water many water borne disease may rise. This can lead even lead death. So such chemical affluents should not be released in water.There should be ban on throwing garbage and other waste materials in water. In such a condition, humans can play vital role,as they can save water from being polluted by increasing awareness in society regarding importance of water and it's conservation strategies. Think about an day without water is like mere survival. As such valuable should be saved from being polluted. ______________________________________You have to write conclusion and some other by your own way. If anyone wants that conclusion contact me______________________________________Hope it will be helpfulThanks❣️❣️ |

Inter halogen compound are more reactive than halogen.why |
| Answer» INTERHALOGEN are all prone to hydrolysis and ionize to GIVE rise to POLYATOMIC ions. The inter halogens are generally more reactive than halogens except F2. This is because A-X bonds in INTERHALOGENS are weaker than the X-X bonds in dihalogen molecules. | |

What happened when toulene reacts to ceo2 or H+ |
|
Answer» Normally, I would have anticipated that Ce(IV) oxidation of toluene in acidic medium would result in the formation of Benzaldehyde and possibly further oxidation to BENZOIC acid. However, the following paper suggests that the main product is Benzyl Alcohol (C6H5CH2OH), as well as trace amounts of Benzaldehyde (C6H5CH=O). This is somewhat UNEXPECTED. The oxidation of toluene by Cerium(IV) has been followed spectrophotometrically in the solution containing H2SO4, Na2SO4 and NACLO4. The effects of toluene, hydrogen ION and sulfate ion concentration as well as of the ionic STRENGTH on the reaction rate have been studied. The main reaction product, identified by gas-chromatography, is benzyl alcohol, besides a small amount of benzaldehyde. The kinetic study revealed a two-stage process. In the first stage, an adduct between toluene and Ce(IV) is formed, undergoing electron transfer during the second stage. Both stages obey first-order kinetics relative to Ce(IV). A complex dependence of pseudo-first-order rate constants on toluene, sulfate and hydrogen ions has been found. Activation parameters are calculated for adduct formation and oxidation process respectively, and a reaction mechanism has been suggested |
