why is a dark bottle used to store hydrogen peroxide and why is acetanilide used in the bottle?

a dark bottle is used b/c light will destroy the peroxide...it's very light sensitive.\n\nas for the second question...i have no clue.

Unless you are talking beauty supplies rather than chemistry.\n\nThen you mix the peroxide with bleach powder or dye to activate them.  10 volume is the weakest, therefore slowest.  50 volume is the strongest, fastest.

The answer is c)\n\nProtonation of the double bond gives the more stable secondary carbonium ion, this reacts with Br- to give the product.\n\nIn the presence of peroxide the reaction goes through a radical mechanism to give the reverse selectivity

They are chemically different. Neither one should be put directly on scrapes- especially alcohol- it will burn like fire and irritate the tissues. Hydrogen peroxide can be used in a diluted form as long as you rinse it off.

Probably for soothing burns from skin exposure.  Refer to the MSDS or call the supplier.

The thing is, spray bottles aren't airtight. If they were, you wouldn't be able to spray anything with them. And it is the air that reduces the power of the bleach. Straight bleach that has not been diluted and is kept in a closed container does deteriorate slightly over time, but retains most of its potency, as long as the container remains closed. The reason for that is that when some of the bleach molecules combine with the air molecules, they use up all the available 'hooks' that allow them to link together. So the rest of the bleach is unaffected and only the surface layer (one molecule thick) will be weakened. \nDoes that make sense?

Probably means 2% hydrogen peroxide, or 2 parts hydrogen peroxide to 100 parts water. 100% would be very explosive and dangerous. Most companies at the strongest only sell 3%. (The rest is water)

Hi. Usually to minimize pressure variations in a home's water system. Fire extinguishers, aerosol cans, Coleman stoves, etc. all use them to store potential energy.

because when its in the bottle it stays moist. glue holds together as it drys...

Never use peroxide cause it is a cancer causing agent. It changes the molecules in your skin

H-O-O-H\n\nThere are NO double bonds in hydrogen peroxide.  If there were, the molecule would be charged.  If you don't believe me, check the link.

Very important. The only difference between life giving water (H2-O) and acid used to dye hair blond, Hydrogen-Peroxide (H-O) is the proper ratio of Hydrogen to Oxygen.  There are hundreds of cases like that.

one mole of hydrogen peroxide contains 6.02 x 10^23 molecules of hydrogen peroxide. And each molecule contains 4 atoms, so the answer is 4 x 6.02 x 10^23.\n\nRemember - a mole is a quantity of something, a mole of cars is 6.02 x 10^23 cars. And that's a lot of cars and even more atoms.

Well, it is a strong oxidant especially in an acidic form, so it could be a problem if it leaked onto anything combustible.  It is also very hazardous to health and environment, so accidental exposure can be a problem.   It will emit very toxic fumes in a fire situation, so it can be quite hazardous to firefighters, especially if they don't know its there.\n\nSome plastics may become brittle with age if it is stored too long, leading to breakage and leakage.\n\nI would say that is the biggest hazard, being accidentally exposed to to an improper containeer or labeling.

Nothing if it was a small amount.  Some believe in drinking food grade peroxide for health benefits.

(a) 1,2-dibromobut-1-ene\n(b) 2,2-Dichlorobutane (based on Markovnikovs rule)\n(c) don't know\n(d) don't know.  Na is often used to reduce multiple bonds in a free-radical manner, however you need a source of H.\n(e) KMnO4 is a very strong oxidising agent and is commonly used as tests for unsaturation.  The side product is MnO2, showing that two atoms of oxygen are transferred to the product.  The product formed I think is 1-hydroxy-butan-2-one.

And H2O2 is hydrogen peroxide (that stuff you put on cuts and it fizzes)....cuz I can almost see that one coming....and H2O3 is dihydrogen trioxide a powerful oxidant produced by antibodies in reaction to invading bacteria in the body.....
