Answer:

The number of moles of  xenon are 1.69 mol.

Explanation:

Given data:

Number of moles of xenon = ?

Volume of gas = 37.8 L

Temperature = 273 K

Pressure = 1 atm

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will put the values in formula.

1 atm × 37.8 L = n ×  0.0821 atm.L/ mol.K   ×273 K

37.8 atm.L =  n × 22.413 atm.L/ mol.

n = 37.8 atm.L /  22.413 atm.L/ mol.

n = 1.69 mol

The number of moles of  xenon are 1.69.

How does erucamide make substances scratch resistant?
dybincka [34]

Answer:

Explained

Explanation:

Erucamide is plastic additive used as anti slip agent and used as scratch resistant. It is used as scratch resistance because

- It reduces coefficient of friction between the polymer layer.

- Slip additives in Erucamide form coalesce along the surface.

-These additives move from the bulk to the part surface to form closed pack layers.
