A). The weaker the IMF the lower the evaporation rates of each liquid. So Pentane had the weakest IMF and Butanol has the strongest.
b).They all evaporate at different rates because of their differences in their bonds. Not all liquids are the same and they will all most likely evaporate at different times
powder is more dense more equality in it salt very salty
The solution process is exothermic because when solution become colder heat energy is released which make the process exothermic. The exothermic process is the process in which heat is released.The solution forms inorder to separate NH4+ ions and Cl- ions
This problem can be solved directly using stoichiometry.
We can actually see that for every mol of P4O10, there are 4 moles of P.
Therefore the total moles of P is:
moles P = 88.5 moles P4O10 * (4 moles P / 1 mole P4O10)
<span>moles P = 354 moles P</span>
