Answer:

Vapor pressure for solution is: 20.48 Torr

Explanation:

Formula to be applied: ΔP = P° . Xm

ΔP = P° - P'

P° → Vapor pressure of pure solvent

P' → Vapor pressure of solution

Xm = Mole fraction.

Let's replace data → 26.5 Torr - P' = 26.5 Torr . 0.227

P' = - (26.5 Torr . 0.227 - 26.5 Torr) →

Which compound can be used to preserve biological specimens? A central C is double bonded to an O, and single bonded to 2 H. A c
Darina [25.2K]

Answer:

A central C is double bonded to an O, and single bonded to 2 H

Explanation:

Methanal, also known as formaldehyde, is a chemical compound used to preserve dead biological specimens for further study. It is called formalin when in a solution and it helps keep specimens in a fresh state by hardening the tissues of the specimen involved.

Formaldehyde is a gaseous compound that has an aldehyde functional group i.e. -CHO and has a chemical formula, H-CHO or CH2O as described in the question that a central C is double bonded to an O, and single bonded to 2 H (see attached image for structural formula).
