Water requires 40.65 kJ of heat per mole to vaporize it completely

Multiply this by the number of moles you have

40.65 kJ x 3.3 moles = 134.145 kJ

Is it possible to change the strength of an acid? Explain how you would do this.
Verdich [7]

Answer:

Reducing or increasing the amount of H+ ions / hydronium (H3O+) ions

Explanation:

To reduce the pH (reducing the strength of the acid) can be done by adding a base (including a conjugate base such as bicarbonate ion) which will absorb the H+ ions either through adsorption or reaction.

Adding more H+ decreases the pH of the acid making it stronger. This can be done by adding HCL that will dissociate and increase the H+ ions.

Which statement regarding liquids is true? 1.can be converted to solids by adding energy in the form of heat 2.occupy a definite
GuDViN [60]

Answer:

4.occupy a definite volume while taking the shape of their container.

Explanation:

Since the particles in a liquid are quite close together (not as close as a solid) they have a definete volume,  and the particles are still able to move around as they wish they have no definite shape and take upon the shape of the container they are placed in.

What type of intermolecular forces are expected between 4-methylcyclohexanone molecules?
Keith_Richards [23]

The answer is dipole-dipole and dipole-induced dipole forces.

The dipole-induced dipole is a kind of interaction induced by a polar molecule by disturbing the arrangement of electrons.

  • In methyl cyclohexanone molecules, there is a permanent dipole moment due to dipole moment vectors not canceling.
  • There is induction of dipole by disturbing the electronic arrangement.
  • A permanent dipole moment is created in this interaction.
  • Dipole-dipole interactions are defined as the forces that is formed from the close linkage of permanent or induced dipoles.
  • These forces are called Van der Waal forces.
  • Proteins contain a large number of these interactions, which vary considerably in strength.
