Answer:
B.) Possibly making an infrence.
Explanation:
Judging on what sshe saw, she can try to infer or come up with an answer. [based on what she observed.]
The words are:
True, false, weak electrolyte, strong electrolyte, non-electrolyte, does not, does, H+ is, OH- is, no ions are, acidic, basic, neutral.
HCN is a weak electrolyte that partially ionizes in water and forms an acidic solution as H+ ions are formed, while acetone is a non-electrolyte that does not form ions in water and the resulting solution is neutral.
It is true that when hydrogen cyanide, HCN, dissolves in water, the solution is weakly conducting and acidic in nature. This is because hydrogen cyanide, HCN, is a weak electrolyte that only partially ionizes in water, and hence does support the movement of charge, albeit to a lesser extent than a strong electrolyte. In addition, since H+ ions are specifically formed from the ionization of HCN in water, the solution is acidic.
It is false that when acetone, CH3COCH3, is dissolved in water a conducting solution results. This is because acetone, CH3COCH3, is a non-electrolyte. It does not ionize in water, and therefore does not support the movement of charge. As such, no ions are formed when acetone is dissolved in water and the solution remains neutral.

B) the end point
Answer:
The direction is missing here.
Explanation:
It is given that,
Veronica's velocity, v = 4.3 m/s
Distance, d = 20 m
Time taken, t = 4.7 s
The velocity of an object is defined as the net displacement divided by total time taken.
We need to find the missing information. We know that velocity is a vector quantity i.e. it has both magnitude and direction. Here, only magnitude of velocity is given but the direction is missing. So, the correct option is (a) " the direction".
please help!!!
