The answer is D. This is because liquids take up the shape of the container they are in, so it is never definite. Where as solids stay the same shape.
Answer:
the acid strength is the order of > >
Explanation:
Given that :
a .
b.
c.
Acid strength is the ability of an acid to dissociate into a proton and an anion. Take for instance.
HA ↔ H⁺ + A⁻
The acid strength of the following compounds above are:
= 1.00 × 10⁻¹⁰
= 6.6 × 10⁻⁴
= 6.3 × 10⁻⁵
As the acid dissociation constant increases the relative acid strength also increases.
From above, the acid strength is the order of > >
, and F⁻ are Bronsted- Lowry acid
Bronsted- Lowry acid are molecule or ion that have the ability to donate a proton.
Answer: The concentartion of solution will be 0.224 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute =
= volume of solution in ml = 275 ml
Now put all the given values in the formula of molarity, we get
Therefore, the concentration of solution will be 0.224 M
