When a solute, sugar in this case, is added, the boiling point of the solution increases. Additionally, the melting point decreases.
To answer your question,
The boiling point of pure water is lower than sugar-water solution.
The melting point is higher for pure water than for sugar-water solution.

Is the equation wrong. Such a equation cannot be formed. pls enter the write equation i will help you
<span>A single-replacement reaction</span>
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.
