In a few sentences, describe the molecular polarity and the intermolecular forces present in ammonium lauryl sulfate.

1 answer:

8 0

The common name of ammonium dodecyl sulfate is ammonium lauryl sulfate (ALS) with molecular formula (CH3(CH2)10CH2OSO3NH4). ... Hence, one intermolecular force that is present in this molecule is electrostatic forces of attraction between the non-polar chain and polar end group.

Hoochie [10]

Answer:

d. 60.8 L

Explanation:

Step 1: Given data

Heat absorbed (Q): 53.1 J

External pressure (P): 0.677 atm

Final volume (V2): 63.2 L

Change in the internal energy (ΔU): -108.3 J

Step 2: Calculate the work (W) done by the system

We will use the following expression.

ΔU = Q + W

W = ΔU - Q

W = -108.3 J - 53.1 J = -161.4 J

Step 3: Convert W to atm.L

We will use the conversion factor 1 atm.L = 101.325 J.

-161.4 J × 1 atm.L/101.325 J = -1.593 atm.L

Step 4: Calculate the initial volume

First, we will use the following expression.

W = - P × ΔV

ΔV = - W / P

ΔV = - 1.593 atm.L / 0.677 atm = 2.35 L

The initial volume is:

V2 = V1 + ΔV

V1 = V2 - ΔV

V1 = 63.2 L - 2.35 L = 60.8 L
