<u>Answer:</u> The correct answer is Ca(OH)_2

<u>Explanation:</u>

A base is defined as the substance which looses hydroxide ions (OH^-) when dissolved in water.

An acid is defined as the substance which looses hydrogen ions (H^+) when dissolved in water.

From the given options:

AgO and NaCl are the salts. Both are ionic salts which are formed from the reaction of a metal and an non-metal.

HF is an acid because it released H^+ ions when dissolved in water. The equation for the ionization of HF follows:

HF\rightleftharpoons H^++F^-

Ca(OH)_2 is a base because it released OH^- ions when dissolved in water. The equation for the ionization of Ca(OH)_2 follows:

Ca(OH)_2\rightleftharpoons Ca^{2+}+OH^-

Hence, the correct answer is Ca(OH)_2

posledela

Answer:

Lead

Explanation:

The subatomic particles within an atom can be used to know the atom or element given.

Of particular interest is the number of protons within the atom.

The periodic table is based on the atomic number of atoms. This atomic number is the number of protons within an atomic space.

So; If we know the number of protons within an atom, we can know the element.

The number of protons given is 82, the element is  therefore lead.

<h2>Answer:  C) 1s²2s²2p⁶</h2>

<h3>Explanation:</h3>

A noble gas has 8 electrons between the p and s orbitals of the outer shell. Helium is the exception because it only has two electrons.

<h3>                       ∴  1s²2s²2p⁶ is the noble gas (neon)</h3>
