Soap is polar because it is not symmetrical in molecularly, this is because it must react with whats on your hand to fully clean it , dish soap is nonpolar/polar in order to combat grease which is also nonpolar, so nonpolar cleans nonpolar and polar cleans polar
It was a compound, hence it needed to be separated into its individual components by chemical means.

Answer:</h3>
4551.37 Pascals
<h3>
Explanation:</h3>
The pressure refers to the force exerted by a substance per unit area.
The pressure is liquid is calculated by;
P = height × density × gravitational acceleration
In this case;
Height = 636.2 mm
Density = 0.7300 g/cm³
g = 9.8 N/kg
We need to convert mm to m and g/cm³ to kg/m³
Therefore;
Height = 636.2 mm ÷1000
= 0.6362 m
Density = 0.73 g/cm³ × 1000 kg/m³
= 730 kg/m³
Then, we can calculate the pressure;
Pressure = 0.6362 m × 730 kg/m³ × 9.8 N/kg
= 4551.3748 pascals
= 4551.37 Pascals
Therefore, the pressure of the column of decane is 4551.37 Pascals

Explanation:
oh will combine with h to form water
The equation to be used to
calculate the heat absorbed when solid melts is the enthalpy of melting. It is
represented as H
= mCpT where H is the heat
released after phase change, m is the mass of the substance, Cp is the specific
heat capacity of the substance and T
is the change in temperature.
H
= mCpT
H
= (18g/1000g/kg)(4.184kJ/kg-K)(293-(-263))
H
= 41.87kJ
