In descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.
It's not repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time.
Hope this helps xox :)
Answer: electrons
Explanation: Electrons have a charge of -1 each. If two left, the remaining atom would have a positive +2 change.
A 1-liter bag of IV solution would contain how many cubic centimeters of fluid?
1000 cc
<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>
