The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L

Answer:
the element must be in the fifth, sixth, or seventh energy shells.
Explanation:
Because the first ionization energy is less than calcium's, the element must be larger and in the next energy shell. Calcium is in the fourth energy shell, so the element must be in the fifth, sixth, or seventh energy shells.
In <em>Mary Cassatt: artist and trailblazer, Vanessa</em> Wright conveys her viewpoint that Cassatt skillfully captures family and home life in her art by <em>describing a little girl in a blue arm chair in detail. </em>
<h3>Painting</h3>
Painting is the practice of applying paint, pigment or color to a medium to a solid surface.
<h3>Impressionists</h3>
The impressionists sought to express their perspective of nature rather than create an exact representation. An impressionist is an entertainer who does impressions.
The little girl in the blue armchair stands as a testament to the newly formed relationship between Mary Cassatt and other impressionists and her own free style of painting.
Mary Cassatt being an impressionists chose to express herself through the impressions of the painting of the little girl in a blue arm chair in details.
