Answer:

17

Explanation:

The number of elementary particles in the atom X = 52

The mass number of atom X = 35

The information required = The atomic number

The number elementary particles of the atom = The number of protons + The number of neutrons + The number of electrons

The mass number of an atom = The number of protons + The number of neutrons

∴ The number of electrons = The number elementary particles of the atom - The number elementary particles of the atom

The number of electrons = 52 - 35 = 17

In a neutral atom, the number of protons = The number of electrons = 17

The atomic number of atom, X = The number of protons in X = 17

Relate the strength of a weak acid to the strength of a conjugate base.
Elenna [48]

Answer:

There is a relationship between the strength of an acid (or base) and the strength of its conjugate base (or conjugate acid): The stronger the acid, the weaker its conjugate base.  The weaker the acid, the stronger its conjugate base.  The stronger the base, the weaker its conjugate acid.

explanation

The strength of an acid and a base is determined by how completely they dissociate in water. Strong acids (like stomach acid) break down or dissociate in water. Weak acids maintains their protons in water.
