made of different kinds of tissues

Explanation:

cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism

1. the simplest unit of life - cell

2. a individual organ - would be made of different kinds of tissues

3. tissues - would be made of one kind of cell

4- an organ system - meets all the needs of a organism

also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah

In an effort to sanitize his water, Beethoven knows that bromine can be used to purify water. If Beethoven has 2.12 x 1022 formula units of aluminum bromide are reacted with excess chlorine gas, how many milliliters of liquid bromine (density = 3.12 g/mL) are formed?

Answers

Answer:

2.7 mL

Explanation:

The equation of the reaction is;

2AlBr3 + 3Cl2 -----> 2AlCl3 + 3Br2

Number of moles in 2.12 x 1022 formula units of aluminum bromide

1 mole of AlBr3 = 6.02 * 10^23 formula units

x moles = 2.12 x 1022 formula units

x = 2.12 x 1022 formula units  * 1 mole/ 6.02 * 10^23 formula units

x = 0.0352 moles of AlBr3

According to the reaction equation;

2 moles of AlBr3 produces 3 moles of Br2

0.0352 moles of AlBr3 produces 0.0352 moles  *  3 moles /2 moles

= 0.0528 moles of Br2

Mass of Br2 produced = 0.0528 moles of Br2 * 159.808 g/mol

Mass of Br2 produced = 8.44g

But density = mass/volume

volume = mass/density

volume of Br2 = 8.44 g/ 3.12 g/mL

volume of Br2 =  2.7 mL

qestions do you have about plate tectonics

Answers

From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past.

Developed from the 1950s to the 1970s, the theory of plate tectonics is the modern update to continental drift, an idea first proposed by scientist Alfred Wegener in 1912 which stated that Earth’s continents had “drifted” across the planet over time. Wegener didn't have an explanation for how continents could move around the planet, but researchers do now: plate tectonics.  

Plate tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth’s core. Earth’s solid outer layer, which includes the crust and the uppermost mantle, is called the lithosphere. It is 100 km (60 miles) thick, according to the Encyclopaedia Britannica. Below the lithosphere is the asthenosphere—a viscous layer kept malleable by heat deep within the Earth. It lubricates the undersides of Earth's tectonic plates, allowing the lithosphere to move around.

Answer:

1. How fast do tectonic plates move? Answer: There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American

2. What are the factors affecting plate tectonics? Answer: The force that causes most of the plate movement is thermal convection, where heat from the Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the plates of the crust along with them.

3. What 3 things support the theory of plate tectonics? Answer: Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.

A 1.5 L pocket of air with a temperature of 295 K rises in the atmosphere. What will be the volume of the air pocket of the t temperature decreased to 2 celsius and the pressure is not changed.

Answers

Answer:

1.4 L.

Explanation:

Applying Charles law,

V/T = V'/T'....................... Equation 1

Where V = Initial volume, V' = Final volume, T = Initial Temperature in Kelvin, T' = Final Temperature in Kelvin.

Make V' the subject of the equation

V' = (V/T)T'..................... Euqation 2

Given: V = 1.5 L, T = 295 K, T' = 2 °C = (2+273) K = 275 K

Substitute these values into equation 2

V' = (1.5/295)275

V' = 1.398

V' ≈ 1.4 L

What is the mass in grams of 9.02x10^28 atoms of Fe​

Answers

Answer:

83.674 grams of Fe

Explanation:

9.02 x 10²⁸ atoms

To convert from atoms to grams, we first need to convert atoms to moles. To do this, divide the atoms by Avogadro's Number, 6.02 x 10²³

9.02 x 10²⁸ ÷ 6.02 x 10²³

= 1.498 moles of Fe

Now we need to convert moles to grams. To do this, multiply the moles by the molar mass of Fe. The molar mass can be found on the periodic table.

1.498 • 55.845

= 83.674 grams of Fe

Hope this helps!

Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill

Answers

Answer:

The rollercoaster has the lowest kinetic energy at the top of the hill.

The rollercaoster has the highest kinetic energy at the bottom of the hill.

Explanation:

The kinetic energy of any solid body in motion is usually computed using this formula:

K.E = [tex]\frac{1}{2}mv^2[/tex]

From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.

We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.

This means that the variations in the K.E are mainly coming from its velocity.

At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.

However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.

1.9x10^23 atoms of sulfur to grams of sulfur

Answers

Answer:

see explanation and punch in the numbers yourself ( will be better for your test)

Explanation:

If you are given atoms you need to divide by Avogadro's number 6.022x10^23

then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams

mm of sulfur is 32 g/mol

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, the grams of sulfur in  1.9x10²³ atoms of sulfur is 9.92g.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance.

Given number of atoms= 1.9x10²³atoms

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

Substituting the values

mole=1.9x10²³÷ 6.022×10²³

mole = 0.31 mole of sulfur

Mole = given mass÷ Molar mass

Molar mass of sulfur=32g/mol

mass of sulfur =0.31 mole ×32g/mol

mass of sulfur=9.92g

Therefore, the grams of sulfur in  1.9x10²³ atoms of sulfur is 9.92g.

Describe the composition of a molecular compound. What are two major characteristics of molecular compounds?

Answers

Answer:

A molecular compound is composed of two or more non metallic elements that are held together by covalent bonds.

The two major characteristics of molecular compounds are;

1.) They are held by covalent bonds

2.) They generally have poor conductivity

Explanation:

A molecular compound is one where two or more molecules come together to form a compound. Unlike ionic compounds that combine by the transfer of electrons, molecular compounds form by sharing electrons. The pairing of the electrons is what holds the molecules together and is known as covalent bonding.

A molecular compound has various characteristics, some of which are;

- Generally low melting and boiling points

- Soft solid forms

- Low enthalpy of fusion and vaporization.

But the two major characteristics of molecular compounds are;

1.) They are held together by covalent bonds.

The elements in a molecular compound share their electrons by having their atoms bond chemically to each other.

2.) They generally have poor conductivity

Molecular compounds do not conduct electricity and heat properly. Because they are formed by sharing electrons, they usually have no free electrons left to conduct electricity.

In the Neighborhood
Ahn vigorously scrubbed windows, a tedious necessity for her family's new Vietnamese restaurant. They had turned the building from homely to gorgeous, but everything had to be absolutely perfect: unique decorations, skillful employees, and fabulous traditional food. Then customers would adore the place, making the business a success.

Ahn shifted her vision to look outside the restaurant as a girl about her age, with abundant red hair, strolled up the street. Ahn’s family had recently moved to this neighborhood, so she had few friends.

The girl paused to study the sign announcing their opening and then looked directly at Ahn with a friendly smile. Ahn smiled back shyly and lifted a hand, accidentally waving with the cleaning cloth. The girl laughed at her amusement and waved back in acknowledgment.

Ahn hesitated, not accustomed to initiating friendship, but she felt courageous, so on a whim she opened the door. "Hello," she said, adding the first thing that entered her head, "do you like Vietnamese food?"

"I don't know, but I like to try new things,” the girl remarked, and then she introduced herself as Gabriela.

Ahn could not think of additional conversation until she had a sudden idea. "Please wait here," she requested, "and I'll be right back." She ran into the adjoining kitchen and explained her idea to her father. He was sympathetic, so seconds later Ahn presented a small package to Gabriela. "Some Vietnamese candy for you to try,” she explained. “If you enjoy it, I hope you'll return to the restaurant sometime, or even visit after school when I'll be here preparing for the dinner service."

"Excellent, I'll see you around soon.” Gabriela headed down the street, glancing back with a cheerful wave. Ahn spent the remainder of the afternoon hoping Gabriela really would return and not think Ahn’s gift was weird.

The following day, Ahn assembled bouquets of artificial flowers, orchids that would never wilt. She was admiring her accomplishment when she heard unexpected tapping and turned to see Gabriela beckoning to her with a plate covered with transparent plastic wrap. Ahn grinned with enthusiasm and opened the door with a cordial greeting.


Gabriela presented the plate and said, "I brought biscuits made from my grandmother's recipe to thank you for the delicious candy.”

"Come in, and we can have some biscuits right now," Ahn stammered, happy inside.

Gabriela entered and rotated to scan the room with its picturesque landscape mural. "Thanks, they really are wonderful, and I'm fascinated to see your restaurant."

As they snacked on the treats, Ahn fumbled for conversation and considered an offer. "Are you good with vocabulary?” she inquired. "I intend to design a publicity pamphlet for the restaurant, and I could use some assistance."

"Certainly!" Gabriela said, adding, "I'm delighted you moved into the neighborhood and thrilled I have a new friend."

Ahn grinned, now positive that the restaurant would make a wondrous impression on the community, that customers would be plentiful, and that she was going to enjoy life here immensely
