Answer: Please see explanation column for answer.

Explanation:  For A two-component mixture containing 1-octene and 1, 4-dimethylbenzene with acetone.

Error-----  The retention factor (Rf) is 0.95 and the two spots are coming simultaneously together producing only one spot indicating that that the choice of  solvent we have used is too polar.  The compounds are interacting rapidly  with the very polar  solvent and have very  low interaction with the stationary phase. than the mobile phase.

Solution:-----, We will need to try other low polar solvent that can allow two spots to be formed on the TLC plate eg is the use of  different percentage s of hexane in ethyl acetate  ether 10% or 20%.

If 1.2 moles of ideal gas occupy a volume of 18.2 L at a pressure of 1.8 ATM what is the temperature of gas in degrees Celsius.
Novosadov [1.4K]

Answer: A 59.5 degree celcius

The equation that we will use to solve this problem is :

PV = nRT where:

P is the pressure of gas = 1.8 atm

V is the volume of gas = 18.2 liters

n is the number of moles of gas = 1.2 moles

R is the gas constant =  0.0821

T is the temperature required (calculated in kelvin)

Using these values to substitute in the equation, we find that:

(1.8)(18.2) = (1.2)(0.0821)(T)

T = 332.5 degree kelvin

The last step is to convert the degree kelvin into degree celcius:

T = 332.5 - 273 = 59.5 degree celcius

What does beta radiation release
yan [13]

A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively.
