If a mirror has a diameter of 10.240 cm and you want to have a coating that is 0.0250 mm thick of Aluminum on it, how many grams of aluminum will you need? How many atoms of aluminum are in the coating? The density of aluminum is 2.702 g/cm^3You may consider the deposited aluminum to be a cylinder from which the volume can be determined using the equation for the volume of a cylinderThanks!
0.0250 mm thick equals 0.00250 cm thick volume (surface area) (thickness) volume (pi r^2) (thickness) volume (3.14) (5.12cm)^2 (0.00250 cm) volume 0.20578 cm^3 find mass using density: 0.20578 cm^3 2.702 g/cm^3 0.5560 grams of Al your first answer, rounded to 3 sig figs is 0.556 grams of Al find moles, using molar mass 0.556 grams of Al 26.98 g/mol 0.020609 moles of Al using Avagadro's number, find atoms: 0.020609 moles of Al 6.022 e23 atoms / mole 1.241 e22 atoms your next answer , rounded to 3 sig figs is 1.24 X 10^22 atoms of Al p.s the answer is Magnesium to your question: A 0.98338 gram sample of a metal (II) carbonate containing an unknown metal M, was heated to give the metal (II) oxide 0.5133 grams of CO2What is the metal? use molar mass to find moles: 0.5133 grams of CO2 44.01 g/mol 0.01166 moles of CO2 by the equation: 1 MCO3 - 1 MO 1 CO2 0.01166 moles of CO2 was produced from an equal 0.01166 moles of MO find molar mass of MCO3 0.98338 gram sample / 0.01166 moles of MO 84.34 g/mole subtract the molar mass of (CO3) 60 g/mol gives the molar mass of the metal as 24 g/mol that's Magnesium
fascia board on an apartment that has an asphalt shingle roofWhere the aluminum pan roof is attached to the wood fascia it's leakingThe eve drip on the apartment is steel and the pan roof is aluminumI was thinking about putting an L shaped piece of flashing under the eve drip flashing down onto the aluminum pan roofBoth are old and dirty and I'm wandering how to properly clean and seal the flashingI'm assuming caulk but I'm not sureAny good ideas or opinions on how I might go about this? Hope someone could give some advice.
you're right on about the L flashing, i would reccomend a peel and stick membrane as a sealerclean the area with soap and water, slip your L flashing under the drip edge then fasten it to the aluminum roof with some short pan head screwsthen, you can get peel and stick at one of the big boxes(home depot, lowes), they even sell smaller rolls for flashing around windows, this should be perfect for youjust peel the back and stick over the bottom part of your L and make sure it sticks on the aluminum at least 6 inches but no more than ten inchesif you have some kind of roller, roll out the membrane after you stick itif you don't, just step on it good all overwhen buying the peel and stick look for the brand name grace it's the best but others will do fineyou could caulk the overlap where the drip edge and L meet if it's not tight and if you have walls or a wall on either side, this same method will work there toothis is not a permanent fix but neither are your roofsdone right tho, it should easily last till your next re-roofgood luck!
Spare me the judgment, I know I'm an idiot, but one day i was cleaning my rifle barrel with some paper towel and it got stuck, i tried a multitude of different things to get it out, but it is in there pretty good, there is also 2 pencils, a screw and some duct tape (because I'm an idiot) stuck in there, is there any way i can clear the barrel from the muzzle end without damaging the rifling?
They have brass and aluminum rod at hardware storesIf you have a .30 caliber a 1/4 aluminum rod will not damage your barrelThat screw might so push with stuff between itSaw it off as not to have too much sticking out to bendPour a little soap and water down the barrel to soften the paper towelYou must have a .30 caliber or bigger because a pencil is close to 5/16 th.
im an azn but my hair isnt the typical straight typeit has some waves in itwhen it dries, its kind of poofy and frizzyive tried blowdrying but it jus get poofiercan anyone help me?

Hey everyone! Okay, so I bought a ball python from petsmart last saturdayAlong with the snake, I bought a snake starter kit for semi-tropical reptilesIt has an Under the Tank heater, which I put under the snake's hide logI also have a heat lamp above that to try and keep things warm in thereThe point of this story is that it is not workingI need to keep his tank humid and warm; however, the glass tank with the metal screen top has made it very difficult for me to keep things warm and humidCan anyone give me any efficient ideas for this? The heat and humidity seem to go right out the top of the tankUghhI can't seem to fix thisAny help would be appreciated.
Get a basking lamp and a 100 watt bulb and put it over the warm side of the tankPut aluminum foil over 2/3 of the screen top and put a towel over itThis will help keep both heatand moisture inPut the water bowl under the heat lampI use sphagnum moss with Aspen bedding because they retain moisture extremely wellMist the bedding and moss dailyGood luck.
My cat somehow got shut into my bathroom on accident and while inside she opened a drawer in front of the doori can only open the door about half an inch and the only thing I have found long enough to fit through the door is a blind turner which bends if you apply pressureThe hinges are also on the inside of the doorThe cat is meowing constantly, how do i get the drawer shut or the door open? This is crazy!
Use a long kitchen knife (wrap it in aluminum foil to protect kitty from the blade) or metal skewer to close the drawerOr, if the opening is large enough, you could use a broomstickA sturdy plastic coat hanger may work as wellYour best bet will be to close the drawer somehowIf all else fails, try going in through the window (if you have one and it's unlocked)It could be worseOne of mine somehow got trapped between the bathroom cabinet and the floor onceI eventually had to cut a hole in the bottom of the cabinet to get her outLOLI know it's frustratingDo you have a fireplace? If so, maybe a fireplace poker will workOr, perhaps an extra long screwdriverA tent pole, maybe?
Where can i find 2 aluminum OVAL tubing?
Air guns usually fire little yellow plastic BBsBB guns usually fire metal BBs and sometimes pellets.
I like to start ready to eat popcorn business in my city.I am confused abt packaging of same.i.e.I know it's crispyness loose when comes in contact with moisture so decided to pack with nitrogen flushing aluminium foil bag just like lays or bingo.Is it OK ? If yes then how many days it will remain same taste as of made ?
You need to use the Jiffy Pop methodGo to your local store, purchase a bag, and go back and hold it over one of the burners on your stove (turned on)Within minutes, it should cause the bag to expand and fill with delicious popcornYay!
