Answer:
If the substance is a liquid or solid, production of an odor would indicate a chemical change.
Explanation:
<span>If the aqueous solution is 34% Licl then it is 100 - 34% water = 66%
From the calculation we've found out that it is 66% water. Then we need to find the weight from a 250 g solution.
66/100 * 250 = 165g
Hence it is 165g</span>
A.)
dG = -(0.008314)(348K) (1.5 * 10-5)
dG = -(0.008314)(348K (-11.107)
dG = 32 kJ/mol (rounded from 32.14)
--------
B.)
AgCl(s) >>>> Ag+ and Cl-
<span>Ksp = {Ag+}{Cl-}
</span><span>1.5 * 10-5 = {Ag+}{Cl-}
</span>1.5 * 10-5 = {X}{X}
<span>X2 = 1.5 x 10-5
</span>X={Ag+}{Cl-}
Sol / AgCl = 3.873E-3 litres/moles
<span>(3.873E-3 moles AgCl/Litre) (143.32 g AgCl / mol)= 0.56g AgCl</span>
The choices for this question are N2, O2 and H2O. I believe the closest correct answer would be N2. H2O would have the strongest one as it is capable of hydrogen bonding which is one strong intermolecular force. To compare oxygen and nitrogen, we look at properties of both substances. Oxygen would have a higher boiling point than nitrogen which means oxygen would require more energy to allow phase transition so it should have a stronger force than nitrogen. Thus, nitrogen would have the weakest intermolecular force.
