Buy a can of spray lacquer and paint it.
Gold does not react with air or water, so it does not tarnish or corrode easily. Copper reacts slowly with air and water to form a patina. Silver reacts with sulfur compounds in the air to form tarnish. Iron reacts quickly with oxygen to form iron oxide (rust).
Kerosene will not dissolve copper. Copper is a non-reactive metal, so it is not easily dissolved by most common solvents.
No, copper does not absorb static electricity. It is a good conductor of electricity, so any static charge on copper will quickly dissipate along its surface.
Copper sulfate is a salt compound made of copper, sulfur, and oxygen. Copper is a metal, whereas sulfur is a non-metal. So, copper sulfate contains both metal and non-metal elements.
Lead is less reactive than copper, so the sulphate ion would stay bound to the copper, so the answer is the same compounds as you started with.
Yes, zinc alloys e.g brass will tarnish given the "right" conditions.Zinc alloys contain copper, and copper is one of the most tarnish-prone metals there is, so any alloy containing copper will tarnish eventually, depending on the percentage of copper alloyed.
Yes, the tarnish is copper oxide. But actually the tarnish is not from when the pennies are made (brand new pennies are shiny); the tarnish is from the copper of the penny reacting with the oxygen in the air over time.The article I have given a link for is quite funny, but it also very informative as regards to pennies, so you might want to check it out.plz decuse the reason why tarnish gets on pennies
So it wont go of
copper and silver dont rust. but copper tarnishes and so does silver. but copper will tarnish faster than silver. also, learn to spell please.
Pennies and the Statue of Liberty are both made of copper but the Statue of Liberty is now green just like pennies become, although they are shiny when they're new. So copper is the metal that has green tarnish.
Copper is the most widely used conductor. Silver is also good except that the tarnish (oxidation) acts as an insulator. Gold does not tarnish but is too expensive; so, it is used in plating to prevent tarnishing to maintain excellent conductivity. Aluminum is nearly as conductive as copper.
Yes but it is not alot so it wont hurt you.
Copper was needed for the war in 1943 so they used steel instead and plated it in zinc so it wouldn't wear and tarnish so quickly, giving it the silvery colour.
Metals that are resistant to tarnish are those that are very unreactive. Things like Gold, Titanium and Platinum are very unreactive under most circumstances- that is why they are good for use as things like jewellry.
Gold does not react with air or water, so it does not tarnish or corrode easily. Copper reacts slowly with air and water to form a patina. Silver reacts with sulfur compounds in the air to form tarnish. Iron reacts quickly with oxygen to form iron oxide (rust).
Tarnish is the oxidation of silver, so yes.
Gold does not tarnish at all, unlike silver that tarnishes from H2S
