41 Using your knowledge of
chemistry and the information in Reference Table H, which statement
concerning propanone and water at 50°C is true?
|
2 | more vapor weaker intermolecular forces |
42 A solution that is at equilibrium must be
|
3 |
a solution is saturated when it is at equilibrium
dissolving and crystallizing are occurring at the same time |
 |
2 | increasing surface area,
concentration, temperature or catalyst increase reaction rate
this is not LeChaterlier because it is not at equilibrium |
 |
1 | Entropy
gases>liquids>solids |
45 Which pH indicates a basic solution?
|
4 |
Bases above 7
acids below 7 |
|
4 | 5 carbons the triple bond is on 2 |
|
4 | use Reference tables |
 |
2 | oxidation charge goes up
electrons on the more positive side |
 |
2 | 2.69d is the half live so it will be reduced by 1/2 |
50 As the elements of Group 1 on the Periodic Table are considered in
order of increasing atomic radius, the ionization energy of each
successive element generally
|
1 | going down group 1 it is easier to remove electrons as they are further from the nucleus |
