When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases.

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 = 1Number of atoms on product side are as follows.
Al = 1Cl = 1Cs = 1To 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 = 3Number of atoms on product side are as follows.
Al = 1Cl = 3Cs = 3Thus, we can conclude that this equation is balanced.
Which of the following is not a force

B)
The plot of land will be covered with grasses and flowers.
C)
The weeds will be replaced by woody shrubs and some small trees.
Answers
Answer:
C
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.

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.

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

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.

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 = 256KOn putting all these values, we get moles as:
n = (1.2)(31) / (0.082)(256) = 37.2 / 20.9
n = 1.7 moles
