How is a molecule and compound similar? How are they different from each other?

Answers

Answer 1

Answer:

A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.

You have a gas that has a pressure of 2 ATM and a volume of 10 L. What would be the new volume if the pressure was changed to 1 ATM ?

Answers

Answer:

20 L

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

We have

[tex]V_2 = \frac{2 \times 10}{1} = 20 \\ [/tex]

We have the final answer as

20 L

if the solution is acidic, which ion is found in greater concentration?

Answers

Answer:

An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water.

The acidic solution indicates the highest concentration of hydrogen or the proton ion in the solution.

What is acidity?

Acidity is the measure of the hydrogen ion in the solution by the pH scale and gives the acidic or basic characteristics to the solution.

The concentration of the hydronium or the hydroxide in the solution is a way to determine the acidic basic nature and the pH and pOH of the solution.

Therefore, in an acidic solution hydrogen ions are in the greatest concentration.

Balance the following equation: AlCl3 + Cs --> CsCl + Al
Group of answer choices

A.2, 6, 6, 2

B.1, 3, 3, 1

C.3, 1, 3, 1

D.2, 3, 1, 3

Answers

Answer: The balanced equation is [tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, [tex]AlCl_{3} + Cs \rightarrow CsCl + Al[/tex]

Here, number of atoms on reactant side are as follows.

Al = 1Cl = 3Cs = 1

Number of atoms on product side are as follows.

Al = 1Cl = 1Cs = 1

To balance this equation, multiply Cs by 3 on reactant side and multiply CsCl by 3 on product side.

Hence, now the equation will be as follows.

[tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]

Here, number of atoms on reactant side are as follows.

Al = 1Cl = 3Cs = 3

Number of atoms on product side are as follows.

Al = 1Cl = 3Cs = 3

Thus, we can conclude that this equation is balanced.

Compare a low-dose rate internal radiation treatment to a high dose rate internal treatment. What do you think are the positives and negatives of each?

Answers

Internal radiation is also called brachytherapy. A radioactive implant is put inside the body in or near the tumor. Getting the implant placed is usually a painless procedure. Depending on your type of cancer and treatment plan, you might get a temporary or a permanent implant. Internal radiation therapy (brachytherapy) allows a higher dose of radiation in a smaller area than might be possible with external radiation treatment. It uses a radiation source that’s usually sealed in a small holder called an implant. Different types of implants may be called pellets, seeds, ribbons, wires, needles, capsules, balloons, or tubes. No matter which type of implant is used, it is placed in your body, very close to or inside the tumor. This way the radiation harms as few normal cells as possible.

During intracavitary radiation, the radioactive source is placed in a body cavity (space) , such as the rectum or uterus.
With interstitial radiation, the implants are placed in or near the tumor, but not in a body cavity. The implant procedure is usually done in a hospital operating room designed to keep the radiation inside the room. You’ll get anesthesia, which may be either general (where drugs are used to put you into a deep sleep so that you don’t feel pain) or local (where part of your body is numbed).

One or more implants is put into the body cavity or tissue with an applicator, usually a metal tube or a plastic tube called a catheter. Imaging tests (an x-ray, ultrasound, MRI, or CT scan) are usually used during the procedure to find the exact place the implant needs to go.

Before being placed, implants are kept in containers that hold the radiation inside so it can’t affect others. The health professionals handling the implants may wear special gear that protects them from exposure once the implants are taken out of the container. High-dose-rate (HDR) brachytherapy allows a person to be treated for several minutes at a time with a powerful radioactive source that’s put in the applicator. The source is removed after 10 to 20 minutes. This may be repeated twice a day over a few days, or once a day over the course of a few weeks. The radioactive material is not left in your body. The applicator might be left in place between treatments, or it might be put in before each treatment.

People getting HDR sometimes stay in the hospital if it involves multiple day treatments and if the applicator is left in place. There may be special precautions to take after the treatment, so be sure to talk to the cancer care team about this. In this approach, the implant gives off lower doses of radiation over a longer period.

Some implants are left in from 1 to a few days and then removed. You’ll probably have to stay in the hospital, sometimes in a special room, during treatment. For larger implants, you might have to stay in bed and lie still to keep it from moving.

Some smaller implants (such as the seeds or pellets) are left in place and never taken out. Over the course of several weeks they stop giving off radiation. The seeds or pellets are about the size of rice grains and rarely cause problems. If your implants are to be left in, you may be able to go home the same day they’re put in. There may be special precautions to take, so be sure to talk to the cancer care team about this.

B)

C)

Answers

Answer:

Explanation:

The weeds will be replaced by woody shrubs and some small trees.

If the forest land is cleared, it is hard to construct a forest again. The cleared land will grow as grass land then if there is no constructions or buildings fills the land. Hence, option B is correct.

What is forstation?

Forestation is the process of formation of forests and dense growth of trees and other kinds of plants. Forests are example of ecosystems and wide variety of plant species and animals are living there.

Nowadays, deforestation is common for the selfish purposes of man to buildups their own amenities so that, many more plants and animals are on the edge of extinction.

There are naturally made forests as well as man made forests. It was results of hard working that to form a forest with all its atmosphere and biodiversity will take longer time. It will not happen within just five years.

Thus, if the forest land is cleared, the empty ground may fill with grasses and flower plants. Hence option B is correct.

Determine the volume of the product containing carbon produced when 15.0 g of C2H2 are reacted with an excess of oxygen gas

Answers

Answer:

25.8 L

Explanation:

Step 1: Write the balanced equation for the complete combustion of acetylene

C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O

Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂

The molar mass of C₂H₂ is 26.04 g/mol.

15.0 g × 1 mol/26.04 g = 0.576 mol

Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂

The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.

Step 4: Calculate the volume corresponding to 1.15 moles of CO₂

At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.

1.15 mol × 22.4 L/1 mol = 25.8 L

an unknown gas has a pressure of 121.6 kPa, a volume of 31 L and a Temperature of 256K. How many moles of gas
are there?

Answers

Answer:

0.031moles

Explanation:

ok so it would help if I knew the marks but 1 mole = 1000L so if the volume was 31L then if you convert you will get that answer

The moles of gas at the given sample of gas is 1.7 moles.

What is ideal gas equation?

Ideal gas equation gives idea about the behavior of gas at different condition & represented as:

PV = nRT, where

P = pressure = 121.6 kPa = 1.2 atmV = volume = 31 Ln = moles = ?R = universal gas constant = 0.082 L.atm / K.molT = temperature = 256K

On putting all these values, we get moles as:

n = (1.2)(31) / (0.082)(256) = 37.2 / 20.9

n = 1.7 moles

Hence required moles of gas is 1.7 mole.
