What is a separated solution?
A separated solution refers to a situation where two or more substances that were once mixed together are divided or isolated from each other through physical or chemical means. This separation allows each substance to be individually analyzed or used.
Can an alloy ever be separated back to its original components?
Yes, though it's usually not trivial to do so.
What metals are extracted using phytomining?
Metals such as nickel, copper, and cobalt are commonly extracted using phytomining. This process involves growing hyperaccumulating plants that can absorb high levels of metals from the soil through their roots. Once the plants are harvested, the metal-rich biomass is collected and processed to extract the valuable metals.
Is nickel a non renewable resource and why?
Nickel is considered a non-renewable resource because it is a naturally occurring mineral that is finite in quantity on Earth. Once mined and extracted, nickel cannot be replenished within a human lifetime due to the slow geological processes involved in its formation. Therefore, it is important to use nickel efficiently and explore alternative sources to minimize depletion and environmental impact.
Name 3 magnetic metals?
All ferrous metals like iron, steel and to some extent stainless steel. Nickel and cobalt are magnetic too. Apart from these there are rare magnetic earths or rocks like 'neodymium'. Magnetite, which was first used by man as a magnetic material (for compass-like purposes) is an oxide of iron. In New Zealand all our "copper" coins are magnetic. This would apply to the coins of any country where they contain high levels of nickel. I once lived on a property in Queensland where lumps of 'gravel' would often cling to my spade ... the soil was heavily laden with magnetite!
Metal used in a nickel coin?
erm....nickel Not quite ... US nickels are actually made from an alloy of only 25% nickel, the rest is copper. Canadian nickels were once pure nickel, but in recent years they've been made of steel because the price of nickel rose to the point where the amount needed would cost more than five cents. Copper. The mix is 75% copper and 25% nickel.
How can salt and water be separated once it is mixed together?
Heat the mixture, which will make the water evaporate, leaving behind the salt.
What year did the US nickel stop being made of silver?
Many people believe that US nickels were once made from silver, like dimes and quarters were, however since its introduction in 1866 nearly all US nickels have been made of a copper-nickel alloy; hence the name "nickel". The nickel did briefly contain a small amount of silver during World War II because nickel was considered a "strategic metal". During this time it was composed of an alloy of copper, silver, and manganese.
Which is more reactive zinc or nickel?
Iron is more reactive than copper because it is higher up on the activity series. There is more reasons to back this up such as outer electrons more tightly bound than others. Those who have less tightly bound electrons are more reactive. Hope this helps you.
Can you separate potassium hydroxide?
No, potassium hydroxide cannot be easily separated back into its original components once it has been mixed together. It is a fully reacted compound.
What is a separated solution?
A separated solution refers to a situation where two or more substances that were once mixed together are divided or isolated from each other through physical or chemical means. This separation allows each substance to be individually analyzed or used.
How can you separate nickel from sand?
soak it in water.... then use a paper filter once the particles are all separated and you got paper either staying at the top or it's at the bottom (depending on the type of filter used
How much silver is in a Canadian 1978 5 cent coin?
None. Canada has never made a silver nickel. In fact, until recently their nickels were really made of pure nickel, unlike those in the U.S. that are mostly copper. Canada DID, however, once make a much smaller 5-cent coin in silver, but it was last minted in 1921 and was never called a nickel because it didn't have any nickel in it.
How is commingled recycled material separated?
Fully commingled, or single-sort, recycling is the system in which papers fibers, metals, and plastics are mixed in a collection trunk rather than being separated into separate commodities. This method is designed so that commingled materials can be handled all at once. Later, the materials will be separated at a materials recovery facility.
