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.

Answer:
the answer is 90g
Explanation:
2g of H2 produce 18g of H2O/10.0g of H2 to produce x the answer is 90g
Essentially all the available nitrogen for life in the form of nitrates and ammonia would eventually disappear. Nitrogen is needed to make proteins and other chemicals so it is required for all life to exist. It gets recycled so it would take many decades in most places before the available nitrogen ran out. Many crops like beans depend on it. Humans can manufacture it but it would be hard on the ecosystems of the world and eventually probably lead to the extinction of all the ecosystems of the world.
Hope this helps!
