d.n.a. interaction with metal complexes?
351215
A lot. A good one is the interaction with the anticancer drug cisplatin. It is actually platinum metal which binds to the DNA of cancer cells, inhibiting them from further multiplying. There are also silver and gold which bind to DNA and form nano-sized particles which are hot hot hot topic right now.

D - it can cause hyperpolarization or depolarization of membrane

If the metal not in the compound is higher on the activity series than the metal in the compound then a reaction will occur and the metals will switch spots. If the metal not in the compound isn't higher on the activity series than the metal in the compound then no reaction will take place. You got to be joking if you think I'm going to be doing 20 problems for you. The only way to learn these is to do them on your own. Just so you know in #6 a reaction will not occur.\n\nHere is an activity series:\nhttp://en.wikipedia.org/wiki/Reactivity_series\n\nREACH doesn't know how to do these, don't listen to his answer.

None. "A more active metal will displace a less active metal from a solution of its salt." Copper and lead are both less active than zinc. Obviously, zinc won't displace itself from zinc sulfate.

Please do your own home work.\n\nI suspect you are missing a symbol, it probably should be,\nN2O4  <==>  2NO2\n\nThink about how each of the changes will effect the equilibrium of the reaction.

The ligand will accomodate electrons from the ligands, forming dative bonds.\n\nThe sub-shell also ceases into two groups of orbitals.  One group will be at a higher energy level as compared with the other.  The difference in energy level is acounted by the strength of the ligand, in other words, by its polarising power.  The stronger the ligand, the greater is the energy difference between the two groups of orbitals.

try Vogel's "Qualitative Inorganic Analysis", I'm pretty sure it has all the answers 4 u.\n\ndont care editions, but for 7th ed, ISBN is 0582218667\n\n****\nokey then, from Vogels\n\n1) when heated, lead nitrate decomposes to white solid lead oxide (PbO), brown gas (NO2) and oxygen gas. Brown gas decolorizes when contact with water. \n\n2) ammonia odur. ammonium compounds are all volatile towards heat and decomposes to ammonia and an acid but quickly recombine if the acid, in this case, hydrochloric acid, is a strong acid.\n\n3) anhydrate copper sulphate is white, hydrate copper sulphate is blue. I have no idea which one you actually heated. If it's anhydrate, no change; if hydrate, blue ---> white.\n\n4) blue precipitate forms initally, but resolve upon excess reagent, clear blue soln results due to the formation of copper complex [blue precipitate: Cu(OH)2*CuSO4, complex: [Cu(NH3)4]^2+]\n\n5) brown precipitates froms [Cu(OH)2], no change with excess reagents.\n\n6) metal-gray stipe (magnesium stipe) gains a redish brown color due to formation of copper metal. Possible decolorization of the soln (depends on how much magnesium u actually put in)\n\n7) volatile reaction, solid metal solves,ignitable gas is formed. (if phenolphthalein is added to water initally, soln becomes pink)

For a given transition metal with a given charge, the color of the complex will change because different ligands change the gap between the delta Oh, the gap between the highest and lowest energy orbitals. If the gap widens, more energy is required to make the transition and the compound will be closer to a red color (in the EM spectrum). If the energy decreases, the compound will appear bluer. The strength of the color is dependent on the charge itself, as LaPorte and Spin Selection Rules apply

Copper can react with nitric acid on two different ways based on the concentration of nitric acid.\n\nIf cold and dilute nitric acid is used, then the reaction yields copper(II) nitrate, nitrous oxide(N2O) and water.\n\nCu + HNO3 ----- Cu(NO3)2 + N2O + H2O\n\nIf hot and conc. nitric acid(a stronger oxidising agent) is used, the reaction yields copper(II) nitrate, nitrogen dioxide(NO2) and water.\n\nCu + HNO3 ----- Cu(NO3)2 + NO2 + H2O\n\nP.S. - Balance the equations yourself(might take some time but use the oxidation no. method)

8-hydroxyquinoline is a complexing ligand used for the extraction of transition metal ions. Commonly used for complexation of nickel, copper, etc. It also has use as a fungicide and antibacterial agent.\n\nIf you omit this material from the experiment, you will fail to extract the nickel from solution.

as far as my knowledge goes SDS is a deterget it helps in distroying the proteins in the sample,EDTA is a chelator which chelates the ions lik Ca+ and Mg[req by enzym to break DNA],and chloroform being organic solvent keeps the DNA away frm the water and prevts it frm getting dissolved
