7 HCl is a polar molecule that experiences dipole-dipole forces. Draw a picture of 2 HC molecules
Identify the partial positive (least electronegative) end and partial negative (most electronegative) end of
the molecules. Explain how dipolo-dipole forces cause molecules to be attracted to one another
8. a). Water is a polar molecule that experiences hydrogen bonding. Draw 2 water molecules and label the
positive and negative ends of the molecule. Draw the hydrogen bond between the 2 water molecules
b). H2S is also polar. Explain why its boiling point is lower than waters.

the answer is either b or c

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
