FAQ

I'm not sure how the Noble gas abbreviation, orbital notation, electron dot structure, and number of protons and neutrons would differ in a aluminum ion in comparison to an Aluminum atom.Appreciate some help here.
The ONLY charge between the Al atom and an Al ion is the loss of three electrons Al - 3e- - Al3+ [2.8.3] - 3 - [ 2.8] This is the electron structure of the nearest rare gas But protons and neutrons don't change.
I'm building a small amplifier for one of my classesThis project takes the place of my mid-term exam so I'd like it to be really niceAnyway, I have all of the soldering/wiring/etcdone, I just have to package it.I've found a clear plastic case (that an iPod touch came in) and I thought that it would be perfect for the size speaker I'm putting inThe plastic isn't flimsy, but it isn't too thick eitherIt can definitely be drilled or cut into without it breakingThe speaker is 2-1/2quot;, if anyone cares.Anyway, I obviously don't want to leave the speaker exposed so my question is what kind of grille should I make? Should I find a mesh-y fabric to wrap over it? Should I drill a bunch of holes? Or should I actually make a grille (cut long narrow holes into the plastic)?I just want this to sound optimal, as well as be visually appealingLet me know if you have any recommendations! Thanks!
How about a piece of steel or aluminium window screen? If it looks too crude or rough, cover it with a piece of fabricAny fabric should work, but the looser the weave the less it will interfere with the sound, especially the higher frequencies [Answer provided from the U.Svia Y!A Canada to circumvent the new, unusable version.]
1.A sheet of aluminum foil has a total area of 1.000ft2   and a mass of 3.636 gWhat is the thickness of the foil in mm? Density of aluminum is 2.6999 g/cm3  .2.Osmium is the densest metal known with a density of 22.57 g/cm3  Calculate the mass in pounds of an osmium sphere 15 cm in diameter.
a.) density mass/volume volume mass/density [but volume area thickness and 1ft 30.48 cm] area thickness 3.636/2.699 1(30.48) thickness 1.347 thickness 1.35/30.48 Thickness 0.044 cm or 0.44 mm b.) volume of the sphere 4(pi)(r^3) volume 4(3.14)(7.5^3) volume 5298.75 cm^3 mass density volume mass 22.57 5298.75 mass 119592.79 gms or 119.592 kg or 263.70 pounds there u go, just remember the formulas.
When an Aluminum atom loses electron(s) (because it is closer to 0 then 8, what ion is formed.I've tried everything but OWL homework program wont accept any of my answers.any ideas?
Blow-in insulation is installed by drilling holes in the interior wall plaster, usually two per stud bay as there may be fire blocking half way upThese holes will have to be patched and the wall re-painted or at least touched upI've found that upgrading windows yeilds a greater effect.
I cooked sum BBQ chicken last time and it was runny in the bottom of the pan/rectangle glass dishAll i did was salt pepper and BBQ sauceAnyone know why it was so runny in the bottom of the panIt was breastsIf you do know what the problem was do you know what I can do to solve it? Thanks
Try searing the chicken prior to baking, I'm assuming you baked them with BBQ sauceSalt and pepper both sides, on a medium hot sauce pan brown both sides with olive oil, bake and just the last 5 minutes drizzle BBQ sauce and when done take them out and loosely cover the chicken with aluminum foil for 5 to 10 minutes before serving to redistribute juice insideNever ever pierce the chicken for doneness immediately after taking out.
If you don't have muffin or cupcake tins/ liners can you use aluminum foil instead?
Use a bit of butter/margarine or shortening and rub it in with a paper towel or waxed paper, dust with flour, put a spoonful in and shake dump it out, you can do this for all the cups, aluminium foil will only make the batter stick, this works and they come out clean, and you will never forget and eat the paper, I do it this way all the timeAlso spray oil like Pam or other generic product work too.
Or, I'd rather know, how long should I grill them on either side before they are cooked through?

I got a problem - I need to find a way to reseal a foil bag (such as used for packaging coffee) so that no one would notice that the bag has been tampered withI do not need to reseal it with vacuum inside, no like thatI have no special equipment.
There is no way you can do itWhatever you do will be noticeableI would come clean rather than being find outSaying sorry is better than being embarrassed.
