Answers

Answer:

/D/ either absorbs or releases energy

Explanation:

During a phase change energy is either absorbed or released.

A phase change is a reversible process which occurs when a substance changes is its state from one form to another.

Phase changes are used to delineate physical changes.

A phase diagram provides a graphic representation of the change. The diagram can be 2 dimensional or 3 dimensional.

Pedro is baking a cake for his experiment on chemical changes. He knows a chemical change will occur when he puts the cake mixture in the oven. He would like to know what will happen when the cake is removed from the oven. What prediction would you make for Pedro's experiment? A. The chemical changes occurred because the chemicals changed. B. The chemical changes occurred because there was a change in light energy. C. The fruit and the hamburgers were affected by an increase in heat energy. D.The fruit and the hamburgers were affected by a decrease in heat energy.

Answers

Answer:

A. The chemical changes occurred because the chemicals changed.

Explanation:

When baking a cake several chemical reactions occur that change the chemical composition of the ingredients used in baking. An ingredient like baking powder releases carbon dioxide when it undergoes a temperature change in the oven. A chemical change is supposed to change the form of a substance.

An endothermic reaction also occurs when the ingredients absorb heat energy to produce several changes. The firmness of the cake occurs because of the heat absorbed by the proteinous content of the egg.

the number of moles in 4.5 x 10^24 atoms of oxegen is​

Answers

Answer:

The answer is 7.48 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{4.5 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 7.47508...[/tex]

We have the final answer as

7.48 moles

What suprising result is explained using this model

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.


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.

challenges we will face terraforming Mars

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.

Answers

Answer:

sulfur

Explanation:

From the given lists of elements, the one with the most electronegativity is Sulfur.

  Electronegativity is of an element is a property that combines the ability of its atom to lose and gain electrons.

It is a measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.

 

Using the Pauling's electronegative table of elements;

   Here are electronegativity values of the given elements;

selenium                 2.4

arsenic                    2.0

phosphorus            2.1

sulfur                      2.5

We see that the value of sulfur is the highest.

32 N of Force. 37 N force. How strong is the net force and in which direction?

Answers

5 units to the left.

Explanation:
They are working against each other. That means you subtract.

32 - 37 = -5

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.

37 - 32 = 5

The 5 moves in the same direction as the 37

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.

PLZ Here is the story and the questions are below it15 points each!!! plsIn South Dakota, Pine Ridge Indian Reservation is as big as Delaware and Rhode Island combined. It has some of the highest poverty rates in the United States. For three years, it has also hosted shows with music written for an orchestra by high school students."It's really a great thing to see these kids, and the pride that the reservation has in having these kids be stars," said David Gier. He is the music leader of the South Dakota Symphony Orchestra.The yearly music academy is one part of the Lakota Music Project. It's a program developed with the orchestra and musicians of the Lakota Native American tribe. The goal is to create cultural cooperation, teaching people about the Lakota and the orchestra."Through music, we are able to show a side of us that nobody gets to see," said Emmanuel Black Bear, a singer. He has been part of the Lakota Music Project since 2009. The native people have "a rich culture," he said. "I wanted to be a part of something where we could show the positive side of our people through music."Black Bear is bringing the Lakota Music Project to Washington, D.C. Native flute player Bryan Akipa and nine members of the South Dakota Symphony are also going. In October, Black Bear will perform at the Smithsonian's National Museum of the American Indian and at Washington National Cathedral. It is for a festival hosted by the PostClassical Ensemble. The goal is to show Native American influences on American music.Matching Two Different Types Of Music TogetherThe Lakota Music Project "deserves to be more widely known," said Joseph Horowitz. He is the PostClassical Ensemble's leader.The project began in 2005. It was soon after Gier started with the orchestra. He wanted to develop community programs, and he learned about tensions in his new community between Native and non-Native Americans.Gier approached local leaders and experts. One was Ronnie Theisz, a writer of books on Lakota culture. The two men talked about creating a project. An idea came one snowy evening at Pine Ridge. Some of the orchestra's musicians met with the Porcupine Singers, a drumming circle on the reservation. They played music for each other.Gier said the keeper of the drum talked about singing old songs and passing on tradition to younger people. It was the main thing both groups shared.There are plenty of differences, too. The timing of the two types of music is different, said Black Bear. "In the beginning, it was kind of difficult to match them together."Hearing The Music Instead Of Trying To Change ItThe first Lakota Music Project tour, in 2009, set themes for the concerts. Theisz became a leader on the project. He suggested grouping the concert around love and death, joy and sadness, with music from each culture. The second half had new works on Lakota themes. The Lakota Music Project is coming to Washington because of Horowitz's support of the Indianist movement. It was in the early 1900s. American composers wrote music based on Native American themes. Horowitz calls it "a major American cultural event that's been totally forgotten."From the Lakota point of view, however, the "Indianist" movement inappropriately uses Native American customs. It's based on a misunderstanding of Native traditions, they believe."Even when they loved to take source music from different Indian tribes," Theisz said of the Indianist composers, "they didn't appreciate it." They wanted to try to improve it, he said."We're trying to counter that," he said. "Hearing the real music is part of the project."The Lakota Music Project's focus remains on building bridges through music."It's just human connection," Gier said, "and feeling like we can make a difference."Question 1Refer to the Newsela article "The Lakota Tribe Wants to Educate People Through Music Project."Part AWhat is an implied idea in the article??A. The Lakota Music Project seeks to improve upon the music of different Indian tribes.B. The goal of the Lakota Music Project is to emphasize the differences between Native American music and European music.C. The Lakota Music Project is a product of the Indianist movement.D. An outcome of the Lakota Music Project is that people of different cultures learn how much they have in common.Question 2Part BWhich two sentences from the text that best support the answer in Part A?A. The Lakota Music Project's focus remains on building bridges through music."B. [The Indianist movement] flourished in the early 20th century as American composers based works on Native American themes.C.
