Zinc is a much more reactive metal than Copper.  Zinc is much higher on the activity series than Copper.\n\nWhen Zinc metal is added to a Copper +2 solution, the Zinc will displace the Copper in solution, precipiating out Copper metal while Zinc ions go into solution.\n\nZn (s) + Cu+2 (aq) --> Zn+2 (aq) + Cu (s)\n\nSince Zinc (II) Sulfate is soluble in water, the Sulfate (SO4-2) ion is a spectator ion in the reaction, it is in solution on both sides of the reaction.

the cell wall of the bacteria. Because in overall, bacteria can be classified as gram positive & gram negative. Those catagories are based on the difference on the reaction of their cell walls. \n\nBacteria are stained with gentian violet and then treated with Gram's solution; after being decolorized with alcohol and treated with safranine and washed in water, those that retain the gentian violet are gram-positive and those that do not retain it are gram-negative. \n\nThe different reactions are cause by the absorption-capability of the cell wall to the decolorization. Those bacteria which can absorpt the color factor (in the other word) the cell wall become decolorized as same as the color factor, are called gram positive. On contrary, for the gram negative.\n\nI hope this information help you to be more understand

Bleach\nBleach is also known by its formal chemical name as sodium \nhypochlorite.In solution, the sodium hypochlorite dissociates, or dissolves, to produce atomic oxygen and \nchlorine. The chlorine and oxygen are very reactive, negatively-charged elements that oxidize components of the bacterial cell.  This oxidation prevents effective operation of the cell's machinery, and the bacterium \ndies.\n\nDetergents\n  Detergents are comprised of long molecules with \nvery different ends. In some types of detergents, one end of the molecule \nis positively charged (insoluble in water), and the other is negatively \ncharged (soluble in water).  These molecules wiggle their way in between \nthe lipids of the bacterium's membrane and cause the cell to spill its \ncontents into the environment, killing the cell.\n\nIodine\nDilute solutions (as little as 1%) of iodine work in much the same way as \nthe chlorine described above.  Looking at a periodic chart, you'll even \nnotice that chlorine and iodine are in the same halogen family, hence their \ncommon mode of action.  Negatively charged iodine combines with proteins \nand disrupts their ability to function normally.\n\nPhenolics\n  There are a variety of phenolics used as disinfectants.  Lysol is perhaps the most famous.  This class of disinfectants works by disrupting proteins, \na common theme as we have seen, but also by disrupting the lipid membrane.  A leaky or broken membrane in addition to faulty proteins are problems too severe for the bacterium to fix in time, and it dies.  Phenolics are also \nbacteriostatic.\n\n  All the disinfectants described above work in an indiscriminate \nmanner.  For example, the chlorine ions bind to many kinds of proteins, not \njust one.  Phenolics cause many types of bacterial species to have leaky \nmembranes.  it is highly unlikely that every protein in a cell will evolve \nan ability to resist the effects of chlorine. \n\nTriclosan \nHere is a disinfectant that does discriminate, or is picky about its \ntarget in a bacterial cell.  You have probably noticed quite a lot of \n"antibacterial" products on the store shelves in recent years.  The active \ningredient in these soaps and detergents is an antibiotic known as \nTriclosan.  Triclosan, however, kills bacteria by acting on a single \nspecific protein that is necessary for the bacterium to make an effective \nlipid membrane.  If this one protein evolves to resist the action of \nTriclosan, Triclosan will no longer be able to kill those bacteria with the \nnew version of the protein.  Scientists are debating the effects of \nbacterial resistance to Triclosan, and the following article will give you \nmore details on a hot topic in the scientific world.\n\nAlcohol \nEthanol (an ingredient in table \nwine) and Isopropanol (also known as rubbing alcohol and poisonous to \nhumans) are very commonly used.  These disinfectants disrupt the structure \nof proteins in the bacteria.  If the proteins are disrupted, or denatured, \nthey cannot perform their highly specific tasks, and the bacterium dies.

Well, I'm not gonna try to explain this or anything, but check this website out:\n\nhttp://www.usm.maine.edu/~newton/Chy251_253/Lectures/Esterification/Esterification.html\n\nScroll down to "Scheme 2: Saponification of an Ester," and that explains the reaction process fairly well.  I don't know if this is what you're looking for, but I hope it helps!

hi my name is Geeth Prajwal from India i hope this will help you\n\n\n\nIn order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples. \n\nMost bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us. \n\nBacteria can also be selectively eradicated by targeting their metabolic pathways. Sulfonamides, such as sulfamethoxazole, are similar in structure to para-aminobenzoic acid, a compound critical for synthesis of folic acid. All cells require folic acid and it can diffuse easily into human cells. But the vitamin cannot enter bacterial cells and thus bacteria must make their own. The sulfa drugs such as sulfonamides inhibit a critical enzyme--dihydropteroate synthase--in this process. Once the process is stopped, the bacteria can no longer grow. \n\nAnother kind of antibiotic--tetracycline--also inhibits bacterial growth by stopping protein synthesis. Both bacteria and humans carry out protein synthesis on structures called ribosomes. Tetracycline can cross the membranes of bacteria and accumulate in high concentrations in the cytoplasm. Tetracycline then binds to a single site on the ribosome--the 30S (smaller) ribosomal subunit--and blocks a key RNA interaction, which shuts off the lengthening protein chain. In human cells, however, tetracycline does not accumulate in sufficient concentrations to stop protein synthesis. \n\nSimilarly, DNA replication must occur in both bacteria and human cells. The process is sufficiently different in each that antibiotics such as ciprofloxacin--a fluoroquinolone notable for its activity against the anthrax bacillus--can specifically target an enzyme called DNA gyrase in bacteria. This enzyme relaxes tightly wound chromosomal DNA, thereby allowing DNA replication to proceed. But this antibiotic does not affect the DNA gyrases of humans and thus, again, bacteria die while the host remains unharmed. \n\nMany other compounds can kill both bacterial and human cells. It is the selective action of antibiotics against bacteria that make them useful in the treatment of infections while at the same time allowing the host to live another day.

UV light causes a homolytic cleavage of the carbon-chlorine bond, generating free radicals that initiate a chain reaction of degradation.\n\nC-Cl goes to  C. + Cl.  The Cl. goes on to further react with PVC at different sites along the chain, splicing it

This one is easy as well... THERE IS NO REACTION!\n\nPB is lower on the activity series, so it cannot replace the Zn in the zinc nitrate...
