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
Hope I helped you out!
Answer:
(a) when both the liquid are mixed, they become completely miscible as the intermolecular forces between them are equal to the intra molecular forces
(b) since the magnitude of intermolecular force = intra molecular forces, Delta H solution=0
(c) Delta H solute = positive
Delta H solvent = positive
Delta H mix = negative
Explanation:
The statement that best describes the variables in a controlled experiment is independent variable while all other conditions are unchanged.
<h3>What is an experiment?</h3>
An experiment is a scientific research, findings or investigation about a subject matter with the aim of validating a claim and establishing theories.
A controlled experiment refers to an experiment in which the variables involved and the control factor are kept in the same group except for one variable which can be changed.
Therefore, The statement that best describes the variables in a controlled experiment is independent variable while all other conditions are unchanged.

The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.
When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.
