A solution contains 450.0 g of sucrose, C12H22011, dissolved in 250.0 g of water.
0.51°C/m. The boiling point of the solution is
C.

Thus the boiling point of a solution is

Explanation:

Elevation in boiling point is given by:

= elevation in boiling point

= boiling point constant =

m = molality = ?

i = vant hoff factor = 1 (for non  electrolyte)

Weight of solvent (water)= 250.0 g = 0.250 kg  

Molar mass of solute (sucrose) = 342 g/mol

Mass of solute (sucrose) = 450.0 g

Thus the boiling point of a solution is

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
