FAQ

I have a small copper tube that snapped off of die cast aluminum float bowlIs it possible to solder that back together or am I wasting my time?.Thanks

a stupid ideayou wasted your time being in school.

A typical car has 17 L of liquid coolant circulating at a temperature of 95 degrees celsius through the engine's cooling systemAssume that, in this normal condition, the coolant completely fills the 4.0 L volume of the aluminum radiator and the 13.0 L internal cavities within the steel engineWhen a car overheats, the radiator, engine, and coolant expand and a small reservoir connected to the radiator catches any resultant coolant overflowEstimate how much coolant overflows to the reservoir if the system is heated from 95 degrees celsius to 108 degrees celsiusModel the radiator and engine as hollow shells of aluminum and steel, respectivelyThe coefficient of volume expansion for coolant is beta410X10^-6 /celsius degrees.

Use baking soda it reacts with it leaving a thin black layer over the foil making it look like iron.

a)?The thermit reaction shows that aluminium is a reactive metal.?Aluminium is used for door-frames and window-frames.How can both these statements be true?b)?Aluminium conducts heat?Aluminium is used as a thermal insulator.How can both these statements be true?

Aluminum will combine with oxygen faster that any other element. Powdered aluminum is even used as a rocket fuel! That’s what is in the space shuttle’s booster rockets. When you have a piece of aluminum at home, say a sheet of foil, the surface has already oxidized. The surface of aluminum oxide protects the underlying metal from further oxidation so the foil remains inert, even in your oven. In foil thermal blankets, the extremely thin amount of aluminum foil reflects radiated heat. That’s its purpose there. It does however conduct latent heat very well. In your oven at home, you can pick up a hot food item by holding only the thin aluminum foil. This is because the foil is so thin that even if the temperature is, say 400 degrees, the tiny amount of foil that your finger touches does not have enough total heat to burn you.

How can I go about crafting with aluminum cans?I am wanting to make a 3D arrow out of aluminum cans, all sides need to be water/air tightI have the cans but I cant figure out what I will need to use to mend them togetherI am a highschool student so weilding would be difficult, thanks.

Find out if you have a threaded or thread-less systemSee the two links.

I bought an older pop-up trailer and the aluminum poles are all corroded on the outside; just feels yuckyHow can I get the corrosion off? Thanks in advance;all answers appreciated.

Steel wool! or very fine sand paper if it is really badYou could even use green scotch bright padsThen to make them sparkle, go to the auto store and get eagle one never dull.

I want the seasonings to be on the chickennot the nasty stuff I'm going to tear off and ignore while at the dinner tableHowever, I'm scared the chicken will dry outAny tips or advice?

Was their metal in the microwave? Thats why.

A cube of aluminum with sides 30 cm rests on the floorThe specific gravity of aluminum is 2.7a) Calculate the weight of the cube.b) Calculate the pressure exerted on the floor by the cube.The answer are 714N and 7930 Pa i'm just not sure how to get the answers especially to part a.

Specific gravity of 2.7 means that one litre of aluminium has a mass of 2.7kgThe cube has volume of 27 litres (because 1litre1dm^3, and 1dm10cm) and therefore a mass of 27x2.7 72.9kgAssuming g9.8, the weight is given by Wmg as 714.42NPressure is force per unit areaThe area of the cube in contact with ground is 0.3x0.30.09m^2Therefore the pressure the cube exerts on the ground is 714/0.097938Pa(slightly different answer, probably due to rounding errors or different value for g)

Balanced equation: 3Cu(SO4) + 2Al -gt; 2Al(SO4)3 + 3CuBeaker A: Mass of aluminum foil was 0.11g and moles of CuSO4 was 0.02mol.Beaker B: Mass of aluminum foil was 0.13g and moles of CuSO4 was 0.01molPlease explain howThanks so much!

Pisgahchemist gave you a reply earlierBut I guess you didn't care for his explanationHere's mineIn the activity series Aluminum is above CopperThat is, in your solution of CuSO4 you have Cu^2+ ions (and SO4^2-)When you add Aluminum foil to the solution (Al), the aluminum will transfer electrons to the Cu^2+ ions, and aluminum ions will result (Al^3+) 2 Al + 3Cu^2+ - 2 Al^3+ + 3Cu Beaker A: moles Al 0.11g x 1mol/27g 0.004 moles moles Cu^2+ 0.02 moles From balanced equation, mole ratio of Cu^2+ to Al is 3 : 2For 0.004 moles Al, you need 3/2 x 0.004 moles Cu^+2 0.006 moles Cu^2+There are 0.02 moles of Cu^2+ so Al is limitingBeaker B: moles Al 0.13g x 1mol/27g 0.005 moles moles Cu^2+ - 0.01 moles For 0.005 moles Al you need 3/2 x 0.005 moles Cu^2+ 0.0075 moles Cu^2+There are 0.01 moles of Cu^2+ so Al is limiting.
