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)
H20 can be a molecule or a compound because it is made up of Hydrogen(H)
and oxygen (O)

Binary compounds<span> are easy to </span>name<span>. The cation is always </span>named<span> first and gets its </span>name<span> from the </span>name <span>of the element. For example, K+ is </span>called<span> a potassium </span>ion<span>. An anion also takes its </span>name<span> from its element, but it adds the suffix -ide to it.</span>
