Answer:
(a) A strong acid has a greater tendency to lose its protons.
(b) A strong acid has a higher Ka than a weak acid.
(c) A strong acid has a lower pKa than a weak acid.
Explanation:
A strong acid has the ability to completely transfer their protons to the water, making a complete dissociation. Instead, a weak acid only dissociates partially, how much it dissociates depends on the acid dissociation constant (Ka).
The weak acids always are in equilibrium, and the equilibrium depends on the acid dissociation constant.
⇄
Thus, a stronger acid with a bigger Ka produces more dissociation and a higher concentration of protons.
The equation that defines pKa is:
Therefore, a higher pKa means a lower Ka and also a weaker acid.
Hello!
To determine the Kb of gallic acid is actually very simple.
The dissociation reaction of Gallic Acid (HGal) is the following:
HGal+H₂O ⇄ H₃O⁺ + Gal⁻
The equation for converting from Ka to Kb is the following:
So, the Kb is 2,19*10⁻¹²
Have a nice day!

The correct reaction equation is:
Answer:
b) 1 mole of water is produced for every mole of carbon dioxide produced.
Explanation: <u>CONVERT EVERYTHING TO MOLES OR VOLUME, THEN COMPARE IT WITH THE COMPOUND'S STOICHIOMETRY IN CHEMICAL EQUATION.</u>
a) <u>22.4 L of gas</u> is produced only when <u>
L of
</u> is reacted with 22.4 L of
. So it is wrong.
b) Since in the chemical equation the stoichiometric coefficient of and
are same so the number of moles or volume of each of them will be same whatever the amount of reactants taken. <u>Therefore it is correct option.</u>
c) molecules is equal 1 mole of
if produced then 3 moles of
is required, which is not given in the option. So it is wrong.
d) 54 g of water or 3 moles of (<em>Molecular Weight of water is 18 g</em>) is produced when 3 moles of
is used but in this option only one mole of
is given. So it is wrong.
