What will happen to the copper sulfate crystal in the test tube filled with distilled water for two hours?

Copper atoms will dissolve into the water, giving off electrons at the anode. At the cathode, the copper ions will be deposited on the electrode and acquire electrons.

What is a rock ball with a crystal filled cavity?
its called a Geode.
Is copper a member of transition elements?
There are two ions formed by copper. In copper(I) ion, the 3d orbital is fully filled, and show no transitional behaviour. Whereas copper(II) ion shows transitional characteristics as it has unfilled 3d orbitals. Therefore, copper is a transitional element.
Even though zinc is after copper in the periodic table leading to an increase in the nulear charge by 1 which should therefore decrease the radius why is it larger than copper?
Zinc has a filled 3d sublevel and 4s sublevel. There is more shielding from the effective nuclear charge within the filled 3d sublevel and also from the filled 4s sublevel. Copper does not have a filled 4s sublevel; recall that one of the 4s electrons "jumps up" to the 3d sublevel thereby stabilizing it by making it filled with 10 electrons. Because of this, the 4s is only half filled and there is not as much shielding within the 4s sublevel allowing the effective nuclear charge to pull the 4th energy level in more toward the nucleus. This will make the overall size of the atom smaller.
How many half-filled orbitals are there in a chlorine atom?
The number of atoms in 1/2 gram of the chemical element copper is 4.7384X10^21. Copper has the atomic number 29 and its symbol is Cu.
Nickel and copper lie next to each other on the periodic table how do their structures differ?
Nickel is 3d8 4s2, while copper is 3d10 4s1. If I remember this copper exception to filling its d shell in order correctly the reason is balance in pairs of electrons as the d shell is filled across the row. Chromium is also an exception in this row. ( do not quote me on this, but ask a chemist )
Will an electrical circuit with a battery be completed by two copper electrodes in an empty beaker when the beaker is filled with distilled water?
No, distiled water will not conduct electricity.
Is Daniell cell a fuel cell?
The Daniell cell (Daniel cell) was invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. As such it is more akin to a battery than a fuel cell.

Why does stator water have to be distilled?
It's inpure otherwise Water that is not distilled is filled with diseases or other naughty bad things that we all know is a big no no to drink... Isn't that right bobo? *looks at the bear* Bobo: aaaarrgh
Which description of electron configuration applies to atoms of potassium chromium and copper?
only five filled sublevels
What kind of water comes in a car battery?
Car batteries are filled with sulfuric acid, not water. The battery fluids get "topped up" with distilled water if they get low.
Is copper a member of transition elements?

Why is shield referred as a mineral storehouse?
because it is filled with minerals like copper, lead, gold, zinc and nickel.
Is drinking crystal light is as good as drinking water?
it is not because half the entire thing is just filled with sugar and it stains your carpet.

What is the purpose of the water reservoir in an iron?
The purpose of the water reservoir in an iron is to reduce the mineral buildup on the iron as well as on the clothes. It is used by simply being filled with distilled water.
What is the correct electron configuration for Cu?
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
