What else can I help you with?
How can you test if a magnetic or non-magnetic materials are better at allowing the magnetic force to pass through?
You can use a device that detects magnetism. A compass needle may suffice.
What observable physical property could you use to tell the difference between copper and iron?
One observable physical property to distinguish between copper and iron is their color. Copper appears reddish-brown, whereas iron has a silver-gray color. Another property is their density, as copper is less dense than iron. Additionally, the way they rust or corrode also differs, with copper developing a greenish patina while iron forms red-brown rust.
What chemical can makes copper float in water?
Copper itself does not float in water due to its density being greater than that of water. However, if you are referring to a chemical reaction that might cause copper to appear to float, certain chemicals can create a buoyant effect by generating gas bubbles. For example, adding an acid like hydrochloric acid to copper can produce hydrogen gas, which could create enough bubbles to momentarily lift small pieces of copper. However, this is a temporary effect and not a true flotation of the copper itself.
Who discovered magnetic separation?
Magnetic separation was discovered by William Fullarton in the 1790s. He observed that a magnet could be used to separate magnetic materials from non-magnetic materials, leading to the development of the magnetic separation technique.
Would copper and zinc nitrate react?
They could, since magnesium is more reactive than copper, and could displace it to form magnesium nitrate.
Could separate iron filings from copper sulphate and copper oxide with a magnet?
Yes, a magnet would remove the iron filings without attracting the copper salts, copper salts are not magnetic.
Can magnets attract a copper wire?
No, copper is not magnetic. That said, if the copper wire has an electric current flowing through it then it will generate its own magnetic field around the wire. It seems feasible that this could be enough to move the wire if you have another magnet near it.
What are the three use of copper?
Copper coins (though are more an alloy than pure copper nowadays), copper pipes in plumbing, copper plus tin and other metals to produce bronze. There is also the copper used to produce electrical wiring. There is even aluminium wires clad (coated) in a thin layer of copper for electrical use. The list could go on...!
Does carbonate produce copper oxide when heated?
Carbonate by itself is an ion that does not contain copper and therefore could not produce copper if heated. However, because carbonate is a negatively charged ion, no substantial number of carbonate ions can exist stably except in association with an equal number of positively charged cations to neutralize the electrical charge of the carbonate ions. If these cations are cations of copper, then copper oxide can be produced by heating the copper carbonate salt.
Is a silver dollar magnetize?
No, silver dollars are not inherently magnetic because they are primarily made of silver, which is not magnetic. However, if a silver dollar is mixed with other metals that are magnetic, then it could become magnetized.
Why are new pennies magnetic but old one not?
What country are you talking about? New U.S. cents are not magnetic; they're made of copper-plated zinc. The only magnetic U.S. cents were the steel ones minted during 1943 so copper could be used in ammunition. New Canadian cents and British pennies are magnetic because they're made of copper-plated steel. The price of copper went up so much that it cost more than a penny to mint the coins, so the governments were losing money on each one. They switched to steel as a cheaper alternative.
How would you separate copper strands and iron filings?
One way to separate copper strands and iron filings is by using a magnet. Copper is not magnetic but iron is, so you can use the magnet to attract and separate the iron filings from the copper strands. Alternatively, you could also use the difference in density between copper and iron to physically separate them using techniques like flotation or panning.
How could you produce a magnetic field using a wire?
Any time an electric current passes through a wire, this will produce a magnetic field. If you want to make the field stronger, loop the wire into coils. The more coils you make, the stronger the field will be.
Would electromagnetic waves exist if changing magnetic fields could produce electric fields but chaning electric fields could not in turn produce magnetic fields?
No, electromagnetic waves require the mutual generation of electric and magnetic fields. This reciprocal relationship allows the waves to propagate through space as self-sustaining oscillations. If only one field could generate the other but not vice versa, electromagnetic waves would not exist.
What is copper odor?
Copper itself is odorless, but when it comes in contact with skin or other materials, it can produce a metallic smell. This smell is often described as musty or like a penny. If you detect a strong, persistent odor of copper, it could indicate a potential issue with copper corrosion or contamination in the environment.
What would you get if you mixed copper with hydrochloric acid?
Mixing copper with hydrochloric acid would produce copper chloride and hydrogen gas. This reaction would dissolve the copper, forming a blue-green solution of copper chloride. The release of hydrogen gas could be observed as bubbles.
How much is a Not Magnetic 1942 P Copper Wheat Penny?
All 1942 pennies are copper (it is the 1943 that is steel). It is a common date worth about 3 cents in average circulated condition and up to a few bucks if uncirculated.
