CBr4 is a symmetric tetrahedral molecule so it will be non-polar.
When gases get cooler the molecules slow down or lose energy and condense so the volume in the tire or soccer ball would decrease and may feel flatter
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
Answer:
The correct answer to the following question will be "90.6 kJ/mol".
Explanation:
The total reactant solution will be:

The produced energy will be:



The reaction will be:
⇒ 
Going to look at just the amounts of reactions with the same concentrations, we notice that they're really comparable.
Therefore, the moles generated by NaCl will indeed be:
= 
= 
= 
Now,
= 
= 
=
