Dentify the molecule with the highest boiling point. chcl3 of2 nh3 c6h6

Option (c) is the correct answer.

Explanation:

A molecule which has hydrogen bonding will have the highest boiling point. So, out of the given options only will have hydrogen bonding.

Whereas in there will be dipole-dipole interactions and no hydrogen bonding within the molecule.

In and , there will be dipole-dipole interaction in both the molecules.

Thus, we can conclude that will have the highest boiling point.

the solar system used to have much dust particles option no d

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 :
