What are some interesting facts about copper?
Copper is a better conductor of heat and electricity than any other metal except silver
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.
Why is copper used for the electrodes?
Because sulphate ions move towards anode (copper) the copper of anode donates 2 electrons to external circuit and becomes +2 ions and moves to the solution so copper anode continuously dissolves in solution.
How much copper is in each US coin?
Except for cents and dollars, modern coins are 75% copper.
Which apparatus is a good conductor of electricity?
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.
What percentage of copper is in pennies prior to 1980?
The coins are 95% copper from 1864 (except 1943) to 1982, from 1857 to 1864 88% copper, 1793 to 1857 100% copper.
Why copper is used for making electrical wire while silver is not?
Copper is used for making electrical wire more commonly than silver because copper is a better conductor of electricity and is more abundant and cost-effective. Silver is a better conductor than copper but is much more expensive, making it less practical for everyday applications like wiring.
Why is colour of copper sulphate blue?
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
What are the steps involved in generating electricity at a power plant?
In all power-generating schemes except solar, some other form of energy is used to produce electrical energy by turning a mechanical generator.
How much copper is in esch U.S coin?
Please rephrase question. Except for cents and dollars, modern coins are 75% copper.
How do you get copper in Australia?
Copper in Australia is primarily obtained through mining operations. Some of the major copper mines in Australia include Olympic Dam in South Australia, Northparkes in New South Wales, and Mount Isa in Queensland. These mines extract copper ore, which is processed and refined to produce pure copper metal.
French beliefs of disease from potatoes?
I never heard that you could have some disease from eating potatoes - except for weight problems when they are cooked with too much fat (fries, etc..)
