Q:aluminum cans?
No, Ed. 1 billion seconds = 31.69 years, so it was the spring of 1976. Also 1 billion minutes ago = about 1901.3 years ago, so Christ would have been about 100. But I digress... Anyway, let's say the average aluminum can is 4.9 tall (I measured a Coke can). 5 billion cans would be 24.5 billion inches tall. This would be 386,679 miles. This would be from the Earth to the moon (about 250,000 miles) and halfway back again!
Q:How many atoms in cube of aluminum?
2.8cm * 2.8cm * 2.8cm= 21.95 cm^3 is volume of Aluminum present Density of Al = 2.7g/cm^3 Convert volume of aluminum into grams of Aluminum, make sure your units cancel 21.95 cm^3 * (2.7g/1 cm^3) = 59.26 g Al Next, find how many moles of Al you have. MW Al = 27g/mol 59.26/27 = 2.19 moles Al Use Avogadro's number to find number of atoms of Al - 2.19 moles Al * (6.022x10^23 atoms/1 mol Al) = 1.32x10^24 atoms Al
Q:cinergy field seats: metal? aluminum?
Aluminum
Q:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid, generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant phenomena.
Q:What kind of paint would you like to paint on the aluminum plate?
Try to brush the high quality magnetization paint, the aluminum plate brush can be brushed, will not move, also won't fall lightly.
Q:Calculate the mass in grams of Iodine (I2) that will react completely with 20.4 g of aluminum?
actually the guy before me did it right but made a mistake at one point 0.07 mole is the # of moles of Al which needs to be changed to moles of product, and then back to find mole of iodide. once thats found then you can use the MW to change it to grams.
Q:copper and aluminum..??
copper aluminum’s conductivity is lower than copper.
Q:General characteristics of pure aluminium plate of pure aluminium plate
Comparison of pure aluminium sheets:1, grade: 1A85, 1A90, 1A93, 1A97, 1A99;Product type: plates, belts, foils, tubes;Main characteristics: Industrial high-purity aluminum;Applications: mainly used in the production of various electrolytic capacitor foil, acid fast container, etc., products have plates, belts, foils and so on.2, grade: 1060, 1050A, 1035;Product type: foil, wire;Main features: industrial pure aluminum has the characteristics of high plasticity, corrosion resistance, electrical conductivity and good thermal conductivity, but the strength is low, it can not be strengthened by heat treatment, cutting is not good. Acceptable contact welding and gas welding;Scope of application: use the advantages of making some structures with specific properties, such as aluminum foil gasket and capacitor, electronic tube isolation network, wire and cable protective sleeve, net, wire core and aircraft parts and trim ventilation system.3, brand: 1100;Product type: Sheet & strip;Main features: for ordinary industrial pure aluminum aluminum content of 99%, can not be strengthened by heat treatment; low strength, but has good ductility, formability, weldability and corrosion resistance; anodic oxidation can improve corrosion resistance, and beautiful surface;Scope of application: mainly produces sheet metal and strip. Suitable for making all kinds of deep stamping products, and is widely used in various fields from cooking utensils to industrial equipment.
Q:What paint is better to paint on the brushed aluminum sheet? Simple process and good adhesion!
Car paint is better, you can go to the auto paint repair department to buy a little, but pay attention to two points: 1., the oil on the aluminum alloy solvent cleaning. 2. can not spray thick, otherwise it will rise.
Q:where can I find buyers for aluminum tabs?
This okorder.com... Now for the bad news, most scrap yards DO NOT accept tabs, they try to say it's a lower grade of aluminium, which is not correct, as it is made out of the same sheet of aluminium as the can was. They just don't want to deal with it, or the people who alway's HEARD SOMEWHERE that tabs have some special value. The truth of the matter is that 1 pound of tabs (1,538 +/- tabs) is only worth about 40 cents. That's it, nothing more. Anybody who say's different is stupid, or a liar, there is no third option. Now, if you want to actually make some money, and your willing to do a little work, this is what I do. I take the tabs that i encounter in daily life, remove all damaged tabs (which are donated to McDonald's House Charities), then I sit there with a pair of needle nose pliars, and I remove that little curly thing that holds the tab to the can (which I save, and yes recycle as aluminium , over 220 pounds to date), now, count your tabs out into 1,000 count ziplock baggies. Each of these bags with 26 cents of aluminium will now sell on E-Bay for $4 plus shipping, which is $6.15 per pound. People need them for arts and crafts, I have sold literally millions on OKorder and my web site. The colored tabs are worth about 2 cents each, MONSTER and NOS tabs are worth about 5 cents each.
