a student is using colored beads to make a model of aluminum sulfate, Al2(SO4)3.
Aluminum atoms are represented by green beads, sulfur atoms by blue beads, and
oxygen atoms by yellow beads. What combination of beads should the student use for
the model?

Answers

The combination of beads should the student use for  the model :2 green, 3 blue and 12 yellow

the modelFurther explanation

In the chemical formula of a compound there are numbers:

1. The number indicates the number of atoms written after the element symbol

2. The number after the parentheses represents the number multiplied by the number of atoms in parentheses.

3. The number before the chemical formula shows the number of molecules behind it, which is usually used in equations

To calculate the beads needed to make a model, we must count the number of atoms of the Al₂(SO₄)₃ molecule

In the Al₂ (SO₄) ₃ molecule there are 3 atoms : Al, S, and O

1. Number of Al atoms: 2 2. The number of atoms S = 3 x 1 = 3 3. The number of atoms O = 4 x 3 = 12

So the combination of beads

2 green(for Al), 3 blue(for S) and 12 yellow(for O)

Answer:

2 blue, 3 yellow, and 12 green

Where are hormones produced in animals, and how are they transported throughout the body?
A. Animal hormones are produced in endocrine glands and travel through the blood.
B. Animal hormones are produced in lymph nodes and travel through the lymphatic system.
C. Animal hormones are produced inside the bones and travel through the nervous system.
D. Animal hormones are produced in sweat glands and travel through the skin.

Answers

Answer:

Vertebrate Endocrine Glands and Hormones

Unlike plant hormones, animal hormones are often (though not always) produced in specialized hormone-synthesizing glands (shown below). The hormones are then secreted from the glands into the blood stream, where they are transported throughout the body.

Answers

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{85}{110} \\ = 0.772727272...[/tex]

We have the final answer as

Answer:

Explanation:

Latent heat of fusion of zinc = 7.322 kJ / mol

molecular weight of zinc = 65 g

450 gram = 450 / 65 = 6.92 mole

Heat required to melt 450 g of zinc = 6.92 x 7.322 kJ

= 50.67 kJ .

How many atoms of aluminum (Al) are contained in 3.73 moles of alumni

Answers

Number of atoms : 2.245 x 10²⁴

Further explanation  

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

n= 3.73 moles

Number of atoms :

Car chases. A man and woman, drenched in sweat, limping from a building as it crumbles to the ground, muster the last of their strength to rescue humanity from its inevitable extinction at the cold, metal hands of humanoid creatures with artificial intelligence gone awry. For decades, books and movies have dictated how we think of robots. Simply the word "robot" can bring to mind images of evil, mechanical creatures bent on taking over the world and wiping out every glimmer of humanity. And yet, the truth of machines is dramatically different. Today's robots hold little in common with their villainous cousins from action-packed science fiction. Most robots have no interest in harming the human population at all; they exist to aid people in making life safer, healthier, and more productive.For example, jobs such as welding and painting are important to civilization as we know it, but experience has taught us that these activities can be hazardous to human health. In addition, fumes in automobile and airplane factories can harm organic bodies that become exposed to their toxins in the assembly process. Even when the best precautions are taken, workers may still suffer from lack of adequate ventilation. What is the answer to these difficult dilemmas? Robots. Because machines don't rely on clean air or comfortable temperatures, because they can function even in the midst of deadly gasses, they can take over with ease where humans would suffer greatly. Working together, humans and robots can get the job done.A robot's job isn't limited to the terrestrial level, either. Even in space, machines such as the R2 humanoid robot at the International Space Station complete dangerous tasks for astronauts, protecting them from potentially deadly situations. And then, when there are mundane but essential tasks to conduct on the space station, R2 takes care of those, as well, freeing up the astronauts' time for more important responsibilities. Thus, in space and on Earth, robots manage to create healthier, happier humans.In fact, there are robots on Earth that exist specifically to boost human health. Just as contact lenses enhance human sight, robotics can increase human mobility. People with disabilities and various forms of paralysis now have hope that they can achieve better range of motion, when before this wasn't possible. With the help of robots, scientists are working to create an exoskeleton that will attach itself to the outside of the human body, establishing a connection to the human brain. Neuroscientist Miguel Nicolelis has a dream. "We are working with the Brazilian government, who is helping fund the project. At the 2014 soccer World Cup celebrations we hope to have a Brazilian teenager with quadriplegia walk out and make the opening kick."Explosions and car crashes may sell tickets for the summer blockbuster, but robots have so much more to offer, and much of it is positive service to humans. At the heart of the field of robotics is not the creation of people-destroying machines with evil artificial intelligence, but something much more useful. Robots aren't our enemies; instead, they are the valuable result of scientific endeavors to create safer lives for people everywhere.Write a summary of the article:Write a main idea sentence for each paragraph of the article.Put your main idea sentences together to create the first draft of your summary paragraph and include a topic sentence.Revise your draft to make it more concise, effective, and objective.Proofread your paragraph for complete sentences, proper punctuation, and correct spelling.Remember that the summary should be objective and should not include your opinions or experiences.thanks and brainleast Which statement best summarizes the role of households in the flow ofgoods?A.
