Answer:
<u>because of the process of refraction of light.</u>
Explanation:
Note, the term refraction refers to the process which results in the <em>bending of light </em>as it passes through a medium. This bending of light can make objects become magnified (or larger), or even smaller.
In this scenario, as the light passes slowly through water it affects how we perceive the objects (the words on the paper) behind the jar (more likely a glass jar). In other words, the light combined with the water refracts (changes direction of) the lights our eyes can see, making the letters seem to change size.

Answer:
7.50×10¯² lbs = 7.50×10¯² lbs × 453.952 g / 1 lbs
7.50×10¯² lbs = 34.0464 g.
Explanation:
From the question given, the following data were obtained:
1 lbs = 453.952 g
7.50×10¯² lbs =.?
Thus, we can obtain convert 7.50×10¯² lbs to grams as follow:
1 lbs = 453.952 g
Therefore,
7.50×10¯² lbs = 7.50×10¯² lbs × 453.952 g / 1 lbs
7.50×10¯² lbs = 34.0464 g
Therefore, 7.50×10¯² lbs is equivalent to 34.0464 g.
Mass of AlCl₃ : 93.39 g
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M
the volume of the solution = 330 cm³=0.33 dm³
the concentration of the solution = 283 g/dm³
