Answer:
I believe
Explanation:
I believe that the answer is B, but I could be wrong. I think it's How much work can be done in a given time, because, In physics, power is the amount of energy transferred or converted per unit time.
Combustion equation of n-hexane:
2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O
a)
Assuming we have 100 moles of air,
Oxygen = 20.9 moles
n-hexane required = 20.9/19 x 2
= 2.2 moles
LFL = Half of stoichometric amount = 2.2 / 2 = 1.1
LFL n-hexane = 1.1%
b)
1.1 volume percent required for LFL
1.1% x 1
= 0.0011 m³ of n-hexane required

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.
