Why is copper alloys more useful than pure copper?
adding alloying elements fills interstitial space in the molecule(between adjacent copper atoms). this increases the strength of the material along with changing other properties.
What does adding heat to matter cause the atoms to do?
Heating up matter makes the space between atoms expand, and the atoms then gain energy and move faster. Solids will change to liquids, and liquids to gas.
Who many atom are in CuSO2?
Copper(II) oxide or cupric oxide or black copper oxide has 2 atoms per molecule: 1 copper atom and 1 oxygen atom. Copper(I) oxide or cuprous oxide or red copper oxide has 3 atoms per molecule: 2 copper atoms and 1 oxygen atom. These are the only stable oxides of copper.
Is copper an element which is made up of atoms?
Yes, everything is made up of atoms, but the atoms in copper are all the same kind, just copper atoms, so it is an element.
What atoms of which elements would you find in copper sulfate?
Copper Sulfate is CuSO4. Therefore, it has 1 atom of Copper, 1 atom of Sulfur, and 4 atoms of Oxygen.
Where is the excess copper from after adding zinc to copper sulfate?
The "excess" metallic copper produced by adding zinc metal to a copper sulfate solution comes from exchanging zinc atoms from the metal for copper atoms from the copper sulfate solution. During the reaction, the zinc atoms are ionized to cations and the copper cations from the solution are reduced to neutral atoms.
Atoms of copper and iron?
compare the structure of the atoms of two different elements like cooper and iron
Is copper conduct electricity a chemical change or a physical change?
It's neither since the copper isn't changing at all. Electrons are just flowing through the copper atoms.
What happens to the atoms in the metal when a piece of copper is pulled into a wire?
The atoms slide over each other and thefore are placed in a new structure.
Why is copper alloys more useful than pure copper?
adding alloying elements fills interstitial space in the molecule(between adjacent copper atoms). this increases the strength of the material along with changing other properties.
Is drawing cooper into wire a chemical change?
No. You start with copper, and when you are finished it is still copper, so there is no chemical change. It's a physical change. You changed the shape and moved some atoms around.
How many atoms are there in a copper and what are they?
Copper is an element. You can have a single atom or many atoms and it's still copper.
Is stretching copper into wire physical or chemical change?
If you meant to ask, "Is stretching copper into wire a physical or chemical change", it's a physical change.
Why a bar of the brass is harder than a bar of copper?
Because brass is an alloy of copper & zinc - the zinc atoms change the geometry of the copper crystals - making it less flexible.
How many atoms of copper are there in 497.3 grams of copper?
The answer is 47,128 x 1023 atoms.
How many atoms are there in a molecule of copper?
Copper is normally encountered as metal which is a giant lattice of atoms.
What did radioactivity reveal about the structure of atoms?
It showed that atoms were divisible, there were subatomic particles within the atom. Atoms could change form and emit an enormous amount of energy.
