How many moles are in a sample of 2.39 x 10^23 atoms of sodium (Na)

Answers

Answer:

The answer is 0.4 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{2.39 \times {10}^{23} }{6.02 \times {10}^{23} } \\ = 0.39700996...[/tex]

We have the final answer as

0.4 moles

Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. Over time, other species are found in the disturbed areas, and the number of pioneer species decreases. Why does the number of pioneer species get less?

Answers

Answer:

The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.

Explanation:

Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. However, with time the number of pioneer species decreases.

The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.


How many atoms are in the following formula?
3Al2O3

Answers

Answer:

15 atoms total

Explanation:

2 Al atoms + 3 O atoms = 5 Al2O3 atoms

5 Al2O3 atoms * 3 = 15

another way to do it is:

2 Al atoms * 3 = 6 Al atoms

3 O atoms * 3 = 9 O atoms

6+9 =15 atoms total

The number of atoms in the given 3Al₂O₃ is 15 atoms.

What are atoms?

Atoms are the smallest unit of every matter. It contains charged particles present inside the atoms. They are electrons, protons, and neutrons. Atoms are of four types, description, isotopes, radioactive, and ions.

These atoms are the ions, that are charged, and the charged ions make bonds with each other to form compounds. Aluminum oxide is a compound that is formed by combining aluminum and oxygen atoms.

The compound is 3Al₂O₃

This means there are three moles of aluminum, and three moles of oxygen.

2 Al atoms + 3 O atoms = 5 Al₂O₃ atoms

5 Al₂O₃ atoms x 3 = 15

The elaborative way is:

2 Al atoms x 3 = 6 Al atoms

3 O atoms x 3 = 9 O atoms

6 + 9 =15 atoms total

Thus, the number of atoms is 15 atoms.

How does the valence electron configuration (entire last energy level configuration) relate to the group number on the Periodic Table? Use the shorthand notation in your discussion.

Answers

Answer:

The valence electron configuration determines the group to which an element belongs to.

Explanation:

The valence electron configuration of an atom of an element refers to the number of electrons in that atoms outermost shell.

The valence electron configuration is related to the group number of an element in that the number of electrons in the valence shell of an atom of an element determines the group to which an element belongs to. For example, all elements having one valence electron belong to group IA of the periodic table. Similarly, all elements having seven valence electrons belong to group VIIA of the periodic table.

This is because, since the reactivity of an element is related to its ability to either gain or lose a certain number of electrons in its valence shell, elements having same number of valence electrons have similar chemical properties.

You are moving 5 units to the left because 37 is negative which means it is moving left. The key word is left. In physics, you would get the same answer if you did it this way.

When many earthquakes are studied, there is another common pattern that emerges: a "Shadow Zone". This is an area, for any earthquake, on the Earth where direct S-waves don't arrive at all and P waves are refracted. What do you think causes these P waves to be refracted? *

Answers

Answer:

Sudden decrease in the velocity at the boundary.

Explanation:

The shadow zone is the zone of the earth from angular distances of 104° to 140° from a known earthquake that does not directly receive any P waves. Now, this shadow zone occurs as a result of S waves getting stopped completely by the liquid core and the P waves being refracted by the liquid core.

From earlier seismic discoveries, this boundary which is the shadow zone that does not directly receive any P-waves was found to be due to the fact that the P-waves were refracted inwards as a result of the sudden decrease in velocity at the boundary.

Answers

Answer:

B. A few positive particles bounced back because they were pushed away from the positive center.

Explanation:

The result of the experiment conducted by Rutherford shows that a few positive particles bounced back because they were pushed away from the positive center.

This is the central theme of Rutherford's experiment on a thin gold foil.

In 1911, Rutherford performed the gold foil experiment that gave the modeling of the atomic structure a great boost. He bombarded a thin gold foil with alpha particles. He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. This led him to postulate that an atom has a small positively charged center where nearly all the mass is concentrated.

Not all protists use flagella or cilia to move. Give an example of another way protists move and identify the type of protist that uses that mode of movement.​

Answers

Answer: One of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia. Those same organelles may be used in feeding as well.

They are in the same family, with similar characteristics.

Answers

Answer:

They are in the same family, with similar characteristics.

Explanation:

The elements in a given group of the periodic table are in the same family and with similar characteristics.

Vertical columns on the periodic table are referred to as a group or family. Elements having the same number of electrons in the outermost shell of their atoms are placed one another in vertical columns. Each resulting vertical column is a group or family. Elements in the same group exhibit similar chemical properties because of the same number of electrons in their atoms' valence shells.

What is the mass of an object with a density of 5.7 g/cm^3 and a volume of 48
cm^3? *

Answers

Answer:

273.6 g

Explanation:

mass =(density)(volume)

mass=(5.7g/cm^3 )(48 cm^3)

cancel out your cm^3 and your are left with grams

multiply (5.7g)(48)=273.6 g

The mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.

What is density?

Density is defined as the degree to which a material is packed together.

It is also defined as a mass per unit volume of the substance.

Its SI unit is kilogram per cubic meter or  gram per meter.

Density can be expressed as

Density = mass / volume

Mass =  density x volume

As given, Density = 5.7 g/cm³

                Volume = 48 cm³

So, Mass =  5.7 g/cm³ x  48 cm³

               =  273.6 grams

Thus, the mass of an object with a density of 5.7 g/cm³ and a volume of 48 cm³ is 273.6 grams.
