FAQ

Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of .143 nmThe masses of a proton, electron, and neutron are 1.6726x10^ -24 g, 9.1094x10^ -28 g, and 1.6749x10^ -24 g, respectivelyThe volume of a sphere is (4)(pie)(r)^3Express the answer in grams per cubic cmThe density of aluminum is found experimentally to be 2.7g/cm3(hint- first you need to figure out how many protons neutrons and electrons are in an Al-27 atom, then figure out the mass of the whole atom, then figure out the volume of the atom using the given radius and the volume formula, so you can use the mass and volume to do the density)Even with the hint i am clueless!

so find volume of aluminum first radius of molecule .143 nm .143 x 10^ -9 m 1.43x10^-8 cm V 4 (pi) (1.43x10^-8 cm)^3 3.675 x 10^-23cm^3 you wanted to convert it because your density is by cubic cm laterthen calculate the total mass from your given infoAl 27 has 13 electron 13 proton and 27 neutron mass of total proton: 13(1.6726x10^ -24 ) 2.174 x 10^-23 g mass of total electrons : 13(9.1094x10^ -28) 1.18422 x 10^-26 mass of total neutron: 27(1.6749x10^ -24) 2.1774 x 10^-23g add the mass , total mass: 4.3529 x 10^-23 g density: mass/volume 4.3529 x 10^-23 g/ 3.675 x 10^-23cm^3 and you get 1.18 g/cm^3 it seems a bit off from the experimental value, which is possible, but mostly likely i type in a number wrongDON'T trust my algebra and calculator plugging skill :) but i can guarantee the method is correct AP chemistry really isn't that bad, don't listen to the stories :)i recommend the books: princeton review and 5 steps to a 5 (- that last book saved me when i took it, raised my score of 2 to a 4 in a week)

What chemicals react with aluminum foil?

DEEZE NUTZ! HA,GOT HEEM.

is a hang glider made of steel conduat? what is it made of and what is the size of the tubing?

Most likely aluminum tubing, probably Al 6061-T6Do not know the specifics of the tubing sizeWould depend upon the designThere could be more expensive models using carbon fiber composite.

like chocolate covered pretzels.can i use aluminum foil to let it set or do i need wax paper?

The problem with the foil is that the food will stick and then the foil will rip and you end up with aluminum covered treatsYou could try greasing the foil, but I wouldn't chance itGet some wax paper:)

I know certain plastics can produce harmful gas when burned, but what about if it is covered in aluminum foil, then oven bake clay? The doll has no hair, and will be completely covered in clay with no parts of the plastic doll directly exposed to the heatI am mainly using the barbie as a inner mold because I have cubital tunnel syndrome and cannot sculpt with my hands for a long period of time, and I need this done within the next few weeksI also have a ceramic kiln, but never tried Primo clay in it before as it is such a low temp clayI thought maybe if I just lowered the temp to maybe 200 and baked for a longer period of time, it would be okSomeone suggested coating the barbie in a plastic high temp spray for like outdoor grills, but I don't know anything about that kind of thingAnyone have any experience doing this? Thanks!

It's hard to say, I've baked mirrors and plastic ball point pens before with polymer clayi would bake it lower than 200, see what the melting point of plastic is :)bake it lower and longer:D

Have you seen these in your area?

You can get a great hat from using a Frito's bag, and putting on your headit's melded together.

I'm not sure how to work this out, what's the answer please 1s2 2s2 2p6 3s2 3p1

1s2 2s2 2p6 3s2 3p1 ?? Clearly, this is aluminum, which has one p-electron and three valence electrons[1s2 2s2 2p6] 3s2 3p1 where [.] indicates the ten inert gas core electrons We can condense the core electrons and represent them with the symbol of the inert gas[Ne] 3s2 3p1 and 3s2 3p1 represent the three valence electrons.

I have received a new CHAR-BROIL Deluxe-8000 gas grill/ovenThis unit is quot;poweredquot; by LP Gas.I am a complete novice when it comes to grilling I am seeking wonderful recipies and techniques to use with my new grill.Thanks for all ideas and now you will know what is causing the pluming black smoke cloud from Texas, so there is no need to worry |D:-) lt;-How does my CHEF CAP look on me?

Slice up one green bell pepper, one red bell pepper, and one vidalia onion into thin stripsMix the strips in a large bowl with two tablespoons of olive oil and some seasoned saltI usually use a spicy seasoned saltLay them flat on a long sheet of aluminum foil (use two sheets to keep it from busting when you turn it)Form a pouch around the veggies, folding the ends enough where you can flip it with tongsPoke a couple of holes in the pouch to let a bit of air inThis will keep the pouch from expanding on the grill and will make it easier to turnGrill on high heat for 15-20 minutes depending on how soft you like themFlip the pouch at least once These are great as a side dish, or smothered on a steak!
