As you can see, the unit of heat of vaporization is in kJ/mol, while the unit for entropy of vaporization is in J/mol·K. Since it is vaporization, this occurs at the boiling point. Thus, the formula would be:
Boiling Point = ΔHvap/ΔSvap
Make sure the units are consistent.
Boiling point = 55.5 kJ/mol * 1000 J/kJ / 148 J/mol·K = <em>375 K or 102°C</em>
Particles in solids are tightly packed together.
Instead of moving past each other like liquids and gases, solids tend to vibrate instead
1. an alpha particle
gamma rays are formally massless, positrons and electrons (beta particles) have negligible mass, but alpha particles have about 4 amu of mass
Answer is 1.41 x 10 with the exponent of 24, atoms
Explanation : Look at the picture i attached.
Answer:
31 moles
Explanation:
The balanced combustion reaction of the wax, 
is shown below as:
As seen from the reaction,
1 mole of wax, on combustion produces 31 moles of carbon dioxide, 
<u>Hence, moles of when 1 mole of wax, is burnt = 31 moles</u>
