- Q:who discovered aluminum and what year did they do it?
- discovered by Sir Humphrey Davy in 1808 Sir Humphrey Davy was from Britain he also named it Aluminum as its name xD
- Q:Elements that bond well with aluminium?
- Fluorine can bond with aluminum. Aluminum has three extra electrons and will easily let the Fluorine atoms use them. Because Aluminum has three, that means three Fluorines can bond. The result is AlF³, also known as Aluminum trifluoride.
- Q:what is the final temperature of 250g of water whose initial Temperature is 25 C if 80-g of aluminum initially?
- Given Data :-- Mass : Aluminium m(a) = 80 g, Water m(w) = 250 g Initial Temperature : Aluminium t₁ = 70 C and Water t₁' = 25 C Final Temperature of both ( aluminium and water ) = T C (assume) Since Aluminium is initially at a temperature higher than that of water, it (aluminium) will lose heat to water . Heat lost by Al = Q = mass of Aluminium x sp.heat capacity of Aluminium x Temp. change = Q = 80 x 0.215 x ( 70 - T ) cal Heat gained by water = Q' = mass of water x sp.heat capacity of water x Temp. change = Q' = 250 x 1 x ( T - 25 ) According to principle of calorimetery . = Heat lost by aluminium = heat gained by water. = 250 x 1 x ( T - 25 ) = 80 x 0.215 x ( 70 - T ) = T = 27.9 C .... ( Rounded to one decimal place )...... Answer Answer .
- Q:How can aluminium ingots be processed into aluminium coils (aluminium sheets)?
- This depends on what kind of ingot, and if it is small, it needs to be melted into a furnace, cast into a large plate, and then rolled on a mill
- Q:How to identify the quality of color coated aluminum coil and sheet?
- Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
- Q:why does hf acid sometimes turn aluminum black?
- Acid is a slow burn on some metals, aluminum tends to turn black when burned where iron turns red when it rusts or burns. I'd say the hf acid left some slight burn marks on your rails.
- Q:Is there a difference between parchment paper and aluminum foil...?
- Just wrap the fish in the parchment and you will be fine. It won't be as air-tight as the aluminum, and it is a lot more flimsey, so the fish may not steam as well, but it will be fine.
- Q:What are the best rust-proof coils? Please tell me the model and manufacturer in Shangdong. Thank you.
- 3003 aluminum coil, AL-Mn series alloy, is the most widely used rust-proof aluminum with the density being 2.73. It is applicable to insulation projects such as pipe insulation, packaging, machine parts, refrigerator, air conditioning and ventilation pipes and other wet environment.
- Q:How does Aluminium and Oxygen bond?
- Aluminum's outer shell is 3, not 13. 13 is the total number of electrons it has. Looking a the periodic table, Oxygen's usual valance state is -2 as an ion. Aluminum's valance state is always +3. This means that oxygen gains 2 electrons to get a charge of -2 and aluminum lose 3 electrons to get a charge of +3. As for electron configuration, aluminum has 13 electrons in total. 2 e- is in the 1st sublevel. 8 e- is in the 2nd sublevel. That leaves 3 e- left but 3 is not a stable number so aluminum wants to lose those 3 e- to become stable. Oxygen has 8 electrons. 2 e- is in 1st. 6 e- is in 2nd. 6 is not a stable number so oxygen wants to gain 2 more e- to become a full set of 8. Aluminum want to lose 3, Oxygen want to gain 2. We need to balance those. 3 x 2 = 6 2 x 3 = 6 Because Aluminum's usual state is +3, we can have 2 Aluminum atoms bonding. If both lose 3 e-, they both have stable outer shell of 8 (2nd sublevel) and lose 6 e- in total. Oxygen's usual state is -2, but there are 6 e- to gain to oxygen can have 3 atoms bonding. If all 3 atoms receive 2 e- in each, then that's 6 and they're all stable, also at 8 e-. So in order to turn them into happy atom, we need 2 Aluminum and 3 Oxygen to bond together. So the chemical formula is Al2O3 (Aluminum Oxide) *** I'm not very good at explaining, I did the best I can. As for the drawing, I can't do that on the computer. It would have been a whole lot easier if I can though.
- Q:Copper chloride + H2O + Aluminum?
- You're looking at a redox reaction. During this process, the copper ions in solution are reduced to form copper metal (visible as dust) and the aluminum metal is oxidized to form aluminum ions. This process is exothermic due to the relative electron affinities and the positions on the activity sequence such that copper has a greater affinity for electrons and is a stronger oxidizing agent. I think aluminum forms a 3+ ion and copper forms either a 1+ or a 2+ ion. Copper's molecular weight is 63g/mol and aluminums weight is 27 g/mol. You would see the weight decrease because aluminum weighs less than Copper and is replaced less frequently due to the higher charge when you figure out the ionics. Nothing was boiling.
