Answer:
1) pure water
2) 0.75 m CaCl2
3) 1.0 m NaCl
4) 0.5 m KBr
5) 1.5 m glucose (C6H12O6)
Explanation:
Boiling point elevation is a colligative property. Coligative properties are properties that depend on the amount of solute present in the system. The boiling point of solvents increase due to the presence of solutes.
The boiling point elevation depends on the number of particles the solute forms in solution and the molality of the solute. The more the number of particles formed by the solute and the greater the molality of the solute, the greater the magnitude of boiling point elevation.
The order of decreasing hoping point elevation is;
1) 0.75 m CaCl2
2) 1.0 m NaCl
3) 0.5 m KBr
4) 1.5 m glucose (C6H12O6)
Answer: sorry I cant help you I need the same answer
Explanation:
The recrystallization solvent ought to have a genuinely low breaking point since it makes it simpler for the solvent to vanish out when the arrangement air drys.The breaking point ought to be bring down the softening purpose of the compound.If the breaking point is bigger than the dissolving purpose of the intensify, the crystals will liquefy and turn out as an oil rather than crystals. This would be difficult to examine.
B) Cu(OH) 2 Is the resulting answer when H20 is decomposed.
The answer is Eukaryotic cells.
