An acid dissociation constant, Ka<span>, (also known as acidity </span>constant<span>, or </span>acid<span>-ionization </span>constant<span>) is a quantitative measure of the strength of an </span>acid<span> in solution. It is the equilibrium </span>constant<span> for a chemical reaction known as </span>dissociation<span> in the context of </span>acid<span>–base reactions.
Hope this helped!

Answer:
A
Explanation:
because number of particle = moles × 6.02 × 10^23
which gives the answer as an A
element is made up of only one type of atoms.
it is pure form of matter
example hydrogen, oxygen, carbon etc
Answer:
8 Nitrogen atoms
Explanation:
Step 1: Define
Chemical Formula - C₈H₁₀(N₄O₂)₂
Step 2: Multiply
(N₄)₂ = N₈
Answer:
Using the Formula Fc = (Valence Electrons) - (Unbound Electrons) - (N bonds in the atom)
Explanation:
Concept: Formal Charge
Let's remember the concept of formal charge as the electric charge of an atom in a given molecule, it is calculated as it follows:
Fc = (Valence Electrons) - (Unbound Electrons) - (N bonds in the atom)
So to answer the question and by knowing the molecule, we can tell
a) Fc + Unbound Electrons + N Bonds of the atom = Valence Electrons, if the valence electrons are fewer than the actual electrons of the atom, it means it is missing electrons.
b) let' s remember the concept of expanded octet as an atom and the Lewis Structure having more than 8 electrons.
So if you sum the Valence Electrons and the N bonds in the atom multiplied by two (There are two electrons in 1 bond) and this number is greater than 8, you could say it has an expanded octet
