Copper is a useful metal because it conducts heat and electricity well, it is also soft and can be bent and molded easily, it also oxidizes/ corrodes very slowly (unlike iron).
There are many uses for copper including:
Electrical wire (electric motors/ generators/ turbines)
Electrical contact switches (power plants/ circuit breakers)
Printed circuit boards contain copper strips connecting components (phones/ PC's, radios, TV's)
Copper plumbing pipe (still in use in some countries)
Money, some countries still use "copper pennies" or variations of these
In more recent times copper and nickle have been replaced in certain currencies (with brass), as the metal content value is sometimes higher than the face value of the coin.
In the past copper was used for roof sheeting, cooking pots, kettles, taps, rails, lightning rods, boat keels.
The shell covering the Statue of Liberty is made from copper, hence its green/ blue color as it oxidizes
Sulfuric acid is commonly used to make copper sulfate by reacting it with copper oxide or copper carbonate. The reaction forms copper sulfate and water, with sulfuric acid providing the necessary protons for the reaction.
To make copper turn green, you can expose it to air and moisture over time. This process, called oxidation, forms a greenish layer of copper carbonate on the surface of the copper.
Brass is mainly an alloy of copper and zinc. Some alloys do have small amounts of arsenic added also.
Sulfuric acid reacts with copper to produce copper sulfate. Copper sulfate is formed when copper reacts with sulfuric acid in the presence of oxygen.
Copper and sulfur combine to form copper (I) sulfide, which is a black solid compound. This reaction occurs when copper is heated with excess sulfur.
copper is an element, you cant make copper
copper and tin make bronze
Sulphuric acid is mixed with copper oxide to make copper sulphate through a chemical reaction.
Yellow, red and slight bit of blue make copper.
Sulfuric acid is commonly used to make copper sulfate by reacting it with copper oxide or copper carbonate. The reaction forms copper sulfate and water, with sulfuric acid providing the necessary protons for the reaction.
you can make copper stuff
Sodium hydroxide is commonly used to make copper sulfate from copper oxide, which is insoluble in water. The reaction between copper oxide and sodium hydroxide forms copper sulfate and water.
To make copper turn green, you can expose it to air and moisture over time. This process, called oxidation, forms a greenish layer of copper carbonate on the surface of the copper.
chemicals
Zinc and copper make brass, and tin and copper make bronze.
Copper is an element in and of itself - you can't "mix" any other substances to get it. Copper is mixed with zinc to make brass, or with tin to make bronze.
Brass is mainly an alloy of copper and zinc. Some alloys do have small amounts of arsenic added also.
