Question

1-What are the values of avocados numbers?
2-What are cations?
3-How does a positive charge appears on the atom?
4-What are molecular ions?
5-Sulpheric acid is stronger then hydronic acid. Which branch of chemistry is this?

Answer 1

Answer:

Cations:

An ion is an atom or molecule that has a net electrical charge. Since the charge of the electron is equal and opposite to that of the proton, the net charge of an ion is non-zero due to its total number of electrons being unequal to its total number of protons.

Molecular ions:

A molecular ion is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero. Unlike a molecule, which has a net charge of zero, this chemical species is an ion.

POSITIVE CHARGE:

That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.

5th answer:

Sulfuric acid (alternative spelling sulphuric acid), also known as oil of vitriol, is a mineral acid ... Upon contact, sulfuric acid can cause severe chemical burns and even ... 4 Ka1 = 2.4×106 (strong acid): HSO − 4 ...
