when amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of
when pol filled another test tube to the top, the liquid formed a low dome, which is evidence of
when amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the
all of these observations indicated the presence of bonds.
pol determined that the ph of the sample is 7, which shows the sample is
based on all of the evidence amanda and pol gathered, the unknown liquid is

Explanation:

1. The upward - curving edges of the liquid in a test tube is an example of capillary action. Capillary action occurs due to the combination of adhesive forces (attraction between liquid and solid) and cohesive forces (attraction between liquid molecules).
2. The formation of a low dome when the test - tube is filled to the top is evidence of surface tension. Surface tension is the result of cohesive forces between liquid molecules at the surface.
3. The ability of the liquid to dissolve table salt indicates its polarity. Polar substances can dissolve ionic compounds like table salt.
4. The presence of hydrogen bonds is indicated by these properties as hydrogen bonds contribute to surface tension, capillary action and the ability to dissolve polar substances.
5. A pH of 7 indicates that the sample is neutral.
6. Based on all the evidence, the unknown liquid is water as water exhibits all these properties such as capillary action, surface tension, polarity, hydrogen - bonding and has a neutral pH.

Answer:

1. Capillary action
2. Surface tension
3. Polarity
4. Hydrogen
5. Neutral
6. Water
