Sulfuric acid is considered as a Bronsted acid because it is a proton donor. When in solution, the molecules of the compound dissociates into ions, the hydrogen ion and the the sulfate ion. It donates the hydrogen ion so it is an acid, a bronsted acid.
Answer:
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
<u>EXPLANATION</u> :
<em>So it is unusual for water to be a liquid at room temperature! Water is liquid at room temperature so it's able to move around quicker than it is as solid, enabling the molecules to form fewer hydrogen bonds resulting in the molecules being packed more closely together.</em>

Answer:
1672 J
Explanation:
We are supposed to find out the energy released by water when cooled from 50° C to 30°C .
We have the relation that ,
H=msΔT
Information is given that s=4.18 J/ g*°C ,
m=20.0 g,
and ΔT is -20° C.
Hence by substituting we get,
H=-20*20*4.18
(minus symbol represents that energy is being released)
1672 J is release when water is cooled from 50° C to 30°C .
