Hello, AbhiKap here I am studying the element Silicon (Si) from the periodic table. It is a Metalloid and I know that it is used in electronics. Can anyone tell me some computer companies that use Silicon in their products. Any companies are fine such as Apple Inc, Samsung, Microsoft, etc... Thanks, Help is appreciated.

Ok so, I have a quesiton. Do you think it will be a good idea to drop everything say in a small pond and then the less dense will float whereas the more dense will sink? Thanks, Help is appreciated.

Well, I tried my best and spent about 30 minutes thinking about it but I only got the idea that the magnets could be used to attract more dense material (If that makes sense) Other than that, I have no idea and I really need help. Thanks, Help is appreciated.

Hello I am in eight grade Science and I really need help on a homework. The homework is the following: Material: (Density (g/cm3)) Aluminum soda cans: (2.7g/cm3) Steel cans: (5.7 g/cm3) Milk jugs: (0.95 g/cm3) Soda bottles: (1.4 g/cm3) You can use the following things to help: • A long conveyor belt • A large tank that can be filled with water • Another large tank labeled “Concentrated sugar water, density = 1.5 g/cm3” • Several powerful magnets hanging above the conveyor belt • Several nets for skimming the tanks and scooping material from the bottoms. Your job: Find a way to separate the four recycled materials. If anyone can help me on this it would be greatly appreciated. You have to find a way to separate this materials using only the things above. Thanks, Help is appreciated.
