Why can gold and copper have the same extensive properties?
Extensive properties have to do with the amount or size of a substance. Gold and copper samples can be made to have the same mass or the same volume, or the same number of moles, or atoms.
How are the element copper and the element silver different?
The elements Copper (Cu) and Silver (Ag) may be in the same group, but they are completely different elements. This means they have a different amount of electrons. Copper has 29 electrons, wheras Silver has 47.
Cu forms two oxides For the same amount of Cu twice as much oxygen was used to form the 1st oxide than to form the 2nd one What is the ratio of the valencies of copper in the first and second oxides?
Copper (II) oxide - CuO; copper valence - 2 Copper (I) oxide - Cu2O; copper valence - 1 Ratio: 2
If you have 5ml of water and you freeze it how many ml of ice do you have?
You will have roughly the same amount of ice as the amount of water you started out with, so probably about 5 mL of ice.
Are copper and iron the same metal?
No, Copper is Cu, Iron is Fe

How many electrons do copper have?
In a chemical element, there are the same amount of protons as there are electrons. In the chemical element copper, there are currently 29 electrons.
How can copper be isoelectronic with hydrogen?
because on the periodic table they both have the same amount of electrons. 1
What is the product for the reaction between lead acetate and copper sulfate?
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.

What is the same about a copper penny and a copper kettle?
Same density
How much energy is saved when Copper is recycled instead of mined?
Recycling copper saves fifteen percent of the energy used in producing the same amount from copper ore. Recycled copper has exactly the same qualities as copper from ore, so it can be recycled over and over without any loss. Copper is non renewable, so it is important to conserve it. Energy saved means fewer greenhouse gas emissions from the fossil fuel saved.
Does all the substances conducteed electritcy show the same amount of conductivity?
no all the conductors do not have the same electrical conductivity as copper is a good conductor and silver is the best but it is costly.
What colour would green and green make?
Twice the amount of the same shade of green that you started with.
Does copper and brass have the same density?
No, copper and brass doesnot have same density.
How do you recover qab charges from icici bank?
There is actually no way you can recover your QAB charges.....I have suffered from the same problem, I have tried absolutely everything and never got my money back. I finally closed my account at ICICI and opened an account in IDBI Bank.....they don't have these kind of charges and they give the same amount of interest.
