Deer populations of the puget sound toefl answers
makvit [3.9K]

The true statement about white-tailed deer is that they no longer live in an area they were once found; option D.

<h3>What is true of the White-tailed deer of the Puget sound?</h3>

The passage describes two types of Deer found in the area called Puget Sound.

The passage indicates that the white-tailed deer together with the black-tailed deer were the once the two prevalent deer of the Puget Sound.

However, only the black-tailed deer are more common now as the white-tailed deer has been restricted to the low marshy areas and Islands of the Columbia river.

Although the reason for this decline was not given, but it can be inferred that environmental changes led to the decline of the white-tailed deer in the area of Puget sound.

When species of organisms are not able to fully adapt to changes in their environment, the population of that species of organism will reduce until they eventually are no more found in that environment.

In conclusion, white-tailed deer are no longer common in the Puget Sound.

How many moles of silver atoms are there in 1. 8 x 1020 atoms of silver?.
Lilit [14]

Answer:

Taking into account the definition of avogadro's number, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.

First, you have to know that it is called Avogadro's Number or Avogadro's Constant. By Avogadro's number it is understood the number of elementary entities (that is, of atoms, electrons, ions, molecules) that exist in a mole of any substance. Its value is 6.023×10²³ particles per mole.

Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.

Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ atoms are contained in 1 mole of silver, then 1.8×10²⁰ atoms are contained in how many moles of silver?

amount of moles of silver= (1.8×10²⁰ atoms × 1 mole)÷ 6.023×10²³ atoms

amount of moles of silver= 2.98×10⁻⁴ moles

Finally, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
