The brass has much lighter color (yellowish to light reddish), then the copper (reddish brown).
The brass is copper mixed with zinc. The more copper in the mix, the darker the color.
Nickel is magnetic.
Brass is a yellow-colored alloy made from copper and zinc, while nickel is a silver-colored metal with a slight blue tint. Brass tends to have a warmer tone and is less shiny than nickel. You can differentiate between the two by comparing their color, shine, and possibly using a magnet (nickel is magnetic, while brass is not).
Red brass has a deeper red color compared to yellow brass, which has a brighter, more yellowish hue. You can also look at the copper content: red brass contains around 85-95% copper and 5-15% zinc, while yellow brass has a lower copper content, around 60-70%, with higher levels of zinc.
No, you cannot differentiate between brass and bronze solely based on sound. Brass is an alloy of copper and zinc, while bronze is an alloy of copper and tin. The compositions of the two alloys affect their physical properties, such as color and hardness.
Brass is an alloy of copper and zinc, giving it a more yellow appearance with slight red tones. Gold, on the other hand, is a precious metal with a distinct bright yellow color and is much softer compared to brass. One way to differentiate them is through a magnet, as brass is not magnetic but gold is not magnetic.
Copper and its alloys have been around for centuries. Brass is an alloy made from copper and zinc, which is why it can be difficult to distinguish copper from brass. Luckily there are a few ways to tell which metal you have. Instructions Step 1 Compare your item to a known copper item. Set the two items beside each other and compare the color and the sound, looking for any difference. Step 2 Look at the color, which is the main way to tell the difference between brass and copper. Copper is a reddish brown metal that turns green when it corrodes, as evident by the Statue of Liberty. The color of brass varies based on the percentage of copper and zinc. Zinc causes the yellow tint most commonly associated with brass, which is why more zinc used in making the brass causes more yellow tones in the brass. Step 3 Listen to the sound and pitch. If an item is hollow, you can test the metal by thumping it and listening to the sound. If you're trying to tell if an instrument is brass or copper, play it. Copper is a softer metal and creates a mellower, rounder sound. Brass has a brighter or slightly higher pitched sound. Step 4 Have your item chemically analyzed. There are a variety of ways that a chemist can distinguish copper from brass. You need to make sure that you have a professional analyze it to prevent damage to the metal. Step 5 Search for markings on the metal. Brass in the United States is regulated by The Unified Numbering System. Brass items are identified by a code starting with C followed by three to five digits. If you see a code like this, it's most likely brass. (end of answer)

well uh..... ask my science teacher
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
Composition and Properties The best way to differentiate between brass and stainless steel is to know their composition. Brass is an alloy of copper and zinc, while steel is an alloy of iron, carbon, and chromium. Just by their base metal, you can easily tell which has suitable properties for particular applications.
Brass door knobs are made up out of an alloy of metals such as aluminium, copper and iron. The main component would be copper. (by the way you spelt door knob wrong) brass doorknobs before 1940 were brass or bronze an alloy of copper and zinc and tin newer things in a store will be steel with a plating unless you pay about $200 for them Aluminum is soft more expensive than steel and hard to plate. Ive also seen them in plastic with metal plating. the easiest way to tell is with a magnet. it will stick to steel.
Hard to tell- regular ethanol is about 10% and E85 is about 15% so maybe 5% difference between the two in or normal fuel supply as of 2014. Brass and E85 ethanol are very reactive with each other
