A piece of aluminum foil 0.550 mm thick and 1.00 cm square is allowed to react with bromine to form aluminum bromide?a) How many mole of aluminum were used? ( The density of aluminum is 2.699 g/cm3.)I keep getting the same answer which I know is wrong. I used a formula to get the volume and then the mass to get the moles, but maybe this is wrong. Could someone explain the process. I got 4.32 x 10-1 mol Al, but the answer is 5.50 x 10-3 mol Al.
0.550mm = 0.055cm 0.055 x 1 x 1 = 0.055cc x 2.699g/cc = 0.1484g Al. Mol.mass = 27 g/mole 0.1484 ÷ 27 = 0.0055 moles. (5.5 x10-?)
Yes, aluminum coils can be used for solar panel applications. Aluminum is a lightweight and durable material that is commonly used in the construction of solar panels. It is an excellent conductor of electricity, making it ideal for capturing and conducting solar energy. Aluminum coils can be used as a backing material for solar panels, providing structural support and helping to dissipate heat. Additionally, aluminum has good corrosion resistance, which is important for solar panels that are exposed to various weather conditions. Overall, aluminum coils are a popular choice for solar panel applications due to their strength, conductivity, and resistance to corrosion.
Can aluminum coil 3003H24 replace 3A21H14?
It is ok in some way as both of them are alumal. The hardness of 3003H24 is similar to that of 3A21H14 after hardening without annealing. Both have good corrosion resistance, plasticity and bad machinability. They cannot be used as load bearing parts even though small load is ok. They cannot be anodized.
Yes, aluminum coils can be used for electrical enclosures. Aluminum is a commonly used material for enclosures due to its excellent conductivity, lightweight nature, and resistance to corrosion. It provides good protection against electromagnetic interference and can effectively dissipate heat. Additionally, aluminum coils can be easily formed and fabricated into various shapes and sizes, making them suitable for electrical enclosures in different applications.
I live in blue ridge ga and have about 2,000 aluminum cans and would like to know how much I can get for them.
The price for scrap aluminum cans varies litteraly every day. Within the last year, it has been between about 28 cents and 50 cents a pound. The last price I saw for clean, flattened cans delivered to the dealer was about 42 cents. As I said, it could be a bit higher or lower than that now. There are about 30-32 cans per pound of aluminum, so your 2,000 cans probably weigh around 64 pounds and could be worth about $27, assuming there has been no big change in the price recently. But that's a delivered price. If you have to drive 10 miles each way and your truck gets 20 mpg, you will be paying for a gallon of gas. If it is 30 miles each way (60 miles total), you are looking at 3 gallons of gas, which is probably about $8, leaving you a profit of around $19, or maybe a little less. That's with some optimistic assumptions, and it doesn't include the cost of big plastic bags to carry the cans. Not very encouraging, is it? Recycling makes sense for a big city or a recycling center, where they can get thousands of cans a day. But it is hard for an individual to make any money at it. i know this is not what you wanted to hear, but I hope it is helpful anyway.
Aluminum coils are widely used in the construction industry due to their lightweight, durability, and corrosion resistance. To improve their performance and appearance, various surface treatments are applied. In the construction industry, there are several common surface treatments for aluminum coils: 1. Anodizing is a widely used method that involves creating an oxide layer on the aluminum surface. This process enhances corrosion resistance, improves weather resistance, and provides coloring options. 2. Powder coating is a popular technique where a dry powder is applied electrostatically and then cured under heat. This results in a durable, smooth, and attractive finish that is resistant to chipping, fading, and scratching. 3. PVDF coating is a high-performance option that offers excellent weather resistance and color retention. It is commonly used in architectural applications where long-term durability and aesthetic appeal are desired. 4. Paint coating, using liquid paint, provides a wide range of color options and finishes. These coatings offer good corrosion resistance and can be tailored to specific design requirements. 5. Brushed finish is achieved by brushing the aluminum surface, creating a textured appearance. This process can be done mechanically or chemically, enhancing the aesthetic appeal of the coils. 6. Laminating involves applying a layer of protective film or laminate to the aluminum coil. This safeguards the coil from scratches, stains, and other damage during handling, transportation, and installation. These surface treatments not only enhance the durability and performance of aluminum coils but also offer customization options. Architects and designers can achieve their desired aesthetics while ensuring long-lasting performance in construction applications.
So on friday we mixed crystaline copper chloride stuffs with water to make a clear blue solution. We then put some aluminum into the solution. The solution began to heat up and there was a redish brown precipitate at the end. What caused the heat? What was boiling? How does the mass of the original aluminum and original copper chloride crystaline stuff compare with the mass of the red/brown power stuff (we strained the liquid out), and the mass of the dried up blue stuff?
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.
Aluminum coils are indeed appropriate for the production of beverage cans. Aluminum is the favored material for this purpose because of its numerous beneficial characteristics. To begin with, aluminum is lightweight, enabling easy transportation and handling. This is especially crucial in the beverage industry, where a substantial number of cans are manufactured and distributed. Furthermore, aluminum possesses high malleability, allowing it to be shaped into the desired form without compromising its structural integrity. This quality makes it perfect for the manufacturing of cans, as it can be effortlessly molded into the cylindrical shape required and withstand the pressure exerted by carbonated beverages. Moreover, aluminum is non-toxic, ensuring that it does not contaminate the beverages stored within the cans. It also acts as a protective barrier against light, oxygen, and moisture, effectively preserving the flavor and quality of the beverages. Additionally, aluminum is recyclable, thus making it an environmentally friendly option for can production. The recycling process for aluminum consumes significantly less energy than the production of new aluminum, rendering it a sustainable material choice. In summary, the appropriateness of aluminum coils for beverage can manufacturing is evident due to their lightweight nature, malleability, non-toxicity, preservation properties, and recyclability.
