woulld you be able to answer these aswell i really dont know how to do this cehmestryExplain how, and why, an atom of chlorine (Cl) and an atom of lithium (Li) would form a chemical bond with each other. (iii)Explain what is meant by electronegativity and how it can be used to determine the nature of a chemical bond. (iv)Write a note outlining what is meant by vapor pressure and explain how the concept is used to define the boiling point of a liquid.
Because of the production of photochemical oxidants from NOx reacting with hydrocarbons in sunlight Noxer blocks are used to rid the NOx from the surroundings through The titanium dioxide (TiO2) on the bocks absorbs ultra-pink radiation from daylight which excites its electrons to a bigger orbital. On the outside of the crystals of TiO2 a reaction happens between oxygen and a high power electron from the TiO2. O2 + e? --O2 ? The excessive vigor electron is then given back to the TiO2 when water then reacts with the oxygen to present H2 O + O2 --H+ + O2 ? + OH Nitrogen dioxide is oxidised to nitrate ions as a result of the hydroxyl radical being an awfully strong oxidising agent NO2 + OH --H+ + NO3 ? The superoxide from response 3 also varieties nitrate ions from nitrogen monoxide. NO + O2 ? --NO3 ? This nitrate is washed away through rain or combines with the concrete within the block.
