1)The emulsifying agent from hand cream, a salt, is prepared from two chemicals.
a. Write the structure of stearic acid.
b. Write the structure of triethanolamine.
c. Write the structure of the salt.
d. In the above salt, label the hydrophobic part of the salt and the hydrophilic part.

Calculate the pressure difference between CH4 and an ideal gas under these conditions. The van der Waals constants for CH 4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
On a Particular summer day, the temperature is 30.0 degrees Celsius and the relative humidity is 80.0% ( which means that the partial pressure of water vapor in the ambient air is 80.0%
The density of liquid oxygen at its boiling point is 1.14 {kg/L} , and its heat of vaporization is 213 {kJ/kg} . How much energy in joules would be absorbed by 2.0 L of liquid oxygen as it vaporized? Express your answer numerically in joules.
A 2.067-g sample of a monoprotic acid was dissolved in water. It took 25.24 mL of a 0.1578 M NaOH solution to neutralize the acid. Calculate the molar mass of the acid.
