unit or 14 mass units.
Two consecutive members of homologous series of Aldehydes: CH

A carbon compound is made up of two parts: R−F, where R is the hydrocarbon part and F is the functional group part.
So, this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the chemical properties of the compounds.
Answer:
-2.74°C
Explanation:
From the formula;
∆T= Kf m i
Where Kf= freezing constant of water
m= molality of the solution = number of moles of solute/ mass of solvent in kilogram
Since number of moles of solute = 3.68 mol and mass of solvent= 2.5Kg
m= 3.68/2.5 = 1.472
Then the freezing constant Kf= -1.86 as given in the question
Since the solution is not ionic, the Vant Hoft factor (i) = 0
Hence;
∆T= Kf m
∆T= -1.86 × 1.472
∆T= -2.74°C

Answer:
The answer to your question is below
Explanation:
Ions are atoms that are electrically charged. There are two kinds of ions
- Cations are ions with a positive charge.
- Anions are ions with a negative charge.
Sodium forms cations because it loses one electron and I can bound to anions like halogens.
Then, the paragraph will be:
"If the sodium ion has a + charge after ionization, then it will interact with a Chlorine ion which has a - charge".
