Their fossilized shells formed these limestone rocks, which, like Gubbio's mountains, were once at the bottom of the ocean. Now exposed, they represent over a million years of a geological time period known as the Cretaceous.

Walter Alvarez found that forming a distinct boundary between the limestone of the two periods was a thin layer of red clay. Immediately below this clay boundary, the Cretaceous limestone was heavily populated with a wide mix of the fossils of tiny marine creatures called foraminifera, or “foram” for short.

On the Atlantic Coast, outside the town of Zumaia, Dutch geologist Jan Smit was studying the forams from a different ancient sea. Their fossilized shells formed these limestone rocks, which, like Gubbio's mountains, were once at the bottom of the ocean.

Gestalt psychology focuses on _____.
jok3333 [9.3K]

Answer:

the brain's ability to memorize information

Explanation:

Gestalt psychology provides a holistic perception to how the brain tends to deal with information it picks. The belief is that the whole is greater than the individual parts. Gestalt is a German word which means whole.

Psychologists that subscribes to this school of thought believes that the brain generally relates with events by creating a complete perceived view of such. For example, christmas lights are pictured as moving because its easier for the brain to relate with such rythm in that way. This helps the brain memorize a piece better than looking at individual relationship between the parts.

What volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid?
kirza4 [7]

The volume of 15.7 M H2SO4 is required to prepare 12.0 L of 0.156 M sulfuric acid is 0.12 L

<h3>Data obtained from the question</h3>

From the question given above, the following data were obtained:

  • Molarity of stock solution (M₁) = 15.7 M
  • Volume of diluted solution (V₂) = 12 L
  • Molarity of diluted solution (M₂) = 0.156 M
  • Volume of stock solution needed (V₁) = ?

<h3>How to determine the volume of the stock solution needed</h3>

The volume of the stock solution needed can be obtained by using the dilution formula as shown below:

M₁V₁ = M₂V₂

15.7 × V₁ = 0.156 × 12

15.7 × V₁ = 1.872

Divide both side by 15.7

V₁ = 1.872 / 15.7

V₁ = 0.12 L

Thus, the volume of the stock solution needed to prepare the solution is 0.12 L
