2) C6H12O6
3) N2
4) O2
Answer:
Explanation:
We have to keep in mind that a good conductor would be a substance that has the ability to produce ions (charged species). These species are responsible for the electricity conduction on water.
Therefore, we have to check which ones of these compounds will produce ions in water. For and we have diatomic molecules (also gases) this type of molecules don't have the ability to produce ions due to his simplicity, they already are very stable.
In the sugar molecule we have a covalent compound. The ions are produced by ionic compounds. So, this molecule can be discarded too.
For we have an ionic compound that have the ability to produce ions:
So, this is the compound that would be a good conductor due to the and the ions.
Write the IUPAC name for washing soda.
moles Cu produced : 0.002
Concentration of copper sulfate (CuSO₄) : 0.319 g/dm³
MW CuSO₄ :
mol CuSO₄ /dm³ :
CuSO₄⇒Cu²⁺ + SO₄²⁻
mol Cu : mol CuSO₄ = 1 : 1 , so mol Cu²⁺=0.002
(2) gains an electron
(3) loses a proton
(4) loses an electron
When a lithium atom forms a Li+ ion, the lithium atom looses an electron. Therefore, option 4 is correct.
The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of components or substructure, electrons, which are members of the lepton particle family's first generation, are typically regarded to be elementary particles.
Quarks make up protons and neutrons, but not electrons. We believe that quarks and electrons are basic particles that are not composed of lesser subatomic particles.
Three protons and three electrons make up a lithium atom. It may become an ion if one of its electrons is lost. It now has a net positive charge since there are more positive protons than negative electrons. It is a positive ion as a result.
Thus, option 4 is correct.

Answer:
(4) loses an electron
it has 3 protons and electrons, proton no. cannot change, to make lithium an ion, it needs to have an exact number of electrons so that the electronic shell can be 2, 8… something like that. So lithium atom loses an electron in order to for Li+ ion. Making the electrons to have 2 as an electronic shell.
