I think it’s A not sure though
The compounds that are present in both waxes and sphingomylin are FATTY ACID AND LONG CHAIN ALCOHOL.
Waxes are diverse type of organic substances which are hydrophobic in nature and they are found in both plant and animals. Sphingomyelin is a type of sphingolipid, which are found in animal cell membranes. It is especially abundant in the membranous myelin sheath which surround some nerve cells.<span />
In the compound Mgo magnesium has an oxidation number of 2 apex
Answer:
The freezing point of the solution is 78.71 °C
Explanation:
Step 1: Data given
Freezing point for the pure solvent is 79.4 °C.
Molality = 0.1 molal
Freezing point depression = 6.9 °C/m
Step 2: Calculate freezing point of the solution
ΔT = i*Kb*m
⇒ with i = the van't Hoff factor: naphthalene = a non-electrolyte, which means that the van't Hoff factor for this solution will be 1
⇒ with Kb = the freezing point depression constant = 6.9 °C/m
⇒ m = the molality = 0.1 molal
ΔT = 1 * 6.9 * 0.1
ΔT = 0.69
Freezing point of the solution = 79.4 °C - 0.69 = 78.71 °C
The freezing point of the solution is 78.71 °C
