0.7 mol of H⁺ ions are present in 2.8 l of 0.25 m hydrobromic acid solution.
Hydrobromic acid is a strong acid, we can assume that all acid molecules dissociate completely to yield H+ ions and dissociated anion.
<h3>The equation for the dissociation of HBr :</h3>
Hbr <em>(s) → </em>H⁺ <em>(aq) </em>+ Br⁻<em> (aq)</em>
<em></em>
moles H⁺ = (
) ( 
) (
) ( 
)
= 0.7 mol
Therefore, 0.7 mol of H⁺ ions is present.

It would be that the cornea is not curved enough, thus not allowing the pupil to expand to perceive further distances clearly. :)
Answer:
mass and volume are independent. Two objects with the same volume can have different masses hence they can have different densities
Explanation:
The mass of atoms their size and how they are arranged determine the density
Answer:
<u>-16200J</u>
Explanation:
(257J/g)(62.9g)
eliminate the variables
u get 16165.3
go to 3 significant digits
u get 16200
and since it is freezing we are taking out energy so it would be
-16200J
The answer is C because you must do all the other things first to get to the that’s part hope that helps
