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 adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.
All of these observations indicated the presence of covalent bonds.
Pol determined that the pH of the sample is 7, which shows the sample is neutral.
Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.
Divergent boundary.
This is the boundary between two tectonic plates move away from each other in opposite directions.
Explanation:
One major example of a divergent boundary is the mid-Atlantic ridge that cuts, longitudinally, across the middle of the Atlantic ocean.
When two tectonic plates move away from each other in opposite directions, the void they leave in between is filled by rising magma from the mantle and cooling to create new crust. A mountainous ridge along a boundary is evidence of a divergent boundary. The Atlantic ocean will therefore continue to widen as the North American and Eurasian Plates move away from each other. As new crust is formed at divergent boundary, old crust is being consumed at convergent boundary on another end of earth. This way tectonic plates of earth renew themselves.

Answer:
1.292 M
Explanation:
<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>
Using the formula:
CaVa/CbVb = na/nb
where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.
In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2
Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2
Ca = 1.292 M
Hence, the concentration of H2SO4 is 1.292 M
