metals or element
I'm guessing that you've got the same science homework as me. It's Iron (or in jumble). Also, I checked on the reactivity series to find out which ones were in the middle, which are Zinc and Iron.
It's Not Cobalt. It's Copper actually in aplus, copper is not an option. cobalt is so i think since i got that question right. it is COBALT! M.C.
He put a piece of wet cardboard on a piece of copper and then put a piece of zinc on top of that, repeated it twelve times and put a copper wire on one end and a zinc wire on the other then made the two wires touch and got an electric spark. ETN
Well you've got Zinc, Chrome and 4 Oxygen atoms in there so i would say.... Zinc Chromate
If it's one you got in change or a bank roll and is copper-colored on the edge, there is absolutely no silver in it.
Since 1982 US cents have been made of copper-plated zinc. The Mint buys large rolls of zinc stock from metal suppliers. The stock is approximately the thickness of a finished cent, with slight differences to allow for changes during the striking process. The process starts a bit like baking cookies: the stock is unrolled (think of a giant roll of dough) and fed into a press that punches out circular blanks, similar to the way a cutter would press out blanks for making cookies. The blanks go through a process to clean them of debris and oils. Next they're fed into a machine that squeezes the edges slightly to produce the raised rim seen on all US coins. After that, the blanks are fed into hoppers that feed high-speed presses that strike the front and back images on each one. Finally the zinc coins are put into a chemical bath that deposits a layer of copper on the outside, both so that the coins look like their bronze predecessors and so that the underlying zinc won't corrode.
Canada discontinued making cents (pennies) in 2013 due to their low value and unprofitable manufacturing costs. The composition has changed many times over the years. The primary compositions were as follows: 2000-2012: 94% steel, 1.5% nickel, 4.5% copper plating 1997-1999: 98.4% zinc, 1.6% copper plating 1978-1996: 98% copper, 1.75% tin, 0.25% zinc 1942-1977: 98% copper, 0.5% tin, 1.5% zinc 1876-1941: 95.5% copper, 3% tin, 1.5% zinc 1858-1859: 95% copper, 4% tin, 1% zinc
To conserve copper for the war effort, cents were minted on zinc-coated steel planchets in 1943, but a few of the pre-war planchets were somehow overlooked and at least 12 copper cents were made and got into circulation.
Bidari is an art of engraving on silver or copper metal. it got its name from a place called bidar in Karnataka
The gold appearance that you see is actually a physical characteristic of the alloy - brass. The silvery appearance is due to the zinc plate derived from the zinc powder in the NaOH solution. Heating the zinc plated penny causes to zinc plate to physically mix with the copper layer of the original penny to form the alloy, brass. The coin appears gold. Blondie 124578963
You didn't give the denomination, but I'm assuming you mean a 1952 Belgium 1 Franc coin. If you've got one of these, it is copper-nickel and contains no silver.
Rocks, magma, what else? WHAT ELSE YOU ARE DUMB read on. you can find diamonds, copper, gold , zinc and lead that is formed within the volcano why do you think that they have got mines in the USA into the volcano
