Which is stronger bleach or chlorine?
Answer: It is true that pool chlorine is stronger than bleach. For bleach and water to be the same strength as pool chlorine and water, you would have to adjust the ratio, increasing the bleach and reducing the water.
Is chlorine a bleach?
Bleach and chlorine are the same chemical, and both will keep your pool sparkling. In truth, bleach contains the same base chemical as pool chlorine. That chemical is, of course, chlorine, and the only major difference between the two products is the concentration strength.
What is the name of Bohr’s model?
According to the Bohr model, often referred to as a planetary model, the electrons encircle the nucleus of the atom in specific allowable paths called orbits. When the electron is in one of these orbits, its energy is fixed.
Why did Bohr model fail?
Bohr’s model of the atom was both a success and a failure. It successfully predicted the frequencies of the lines in the hydrogen spectrum, so it seemed to be valid. Nevertheless the model was a total failure when it tried to predict energy levels for atoms with more than one electron.
Why is Niels Bohr important?
What was Niels Bohr’s most important discovery? Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus.
What are the main uses of chlorine?
Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides. About 20% of chlorine produced is used to make PVC.
What is neon Bohr diagram?
Two electron shells surrounding the nucleus, containing 2 electrons in the n=1 shell and 8 electrons in the n=2 shell. Bohr’s model of the atom described the atom as a series of energy levels called principle quantum shells, at progressively greater distance from the nucleus.
What questions did Bohr ask?
He had many answers to this problem ; he was just thinking of the best one. I excused myself for interrupting him and asked him to please go on. In the next minute he dashed off his answer which read : “Take the barometer to the top of the building and lean over the edge of the roof.
What’s the chemical name for chlorine?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.
What is the symbol for beryllium?
Be
What did Bohr say?
In 1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.
How do Bohr models work?
In the Bohr model of the atom, electrons travel in defined circular orbits around the nucleus. The orbits are labeled by an integer, the quantum number n. Electrons can jump from one orbit to another by emitting or absorbing energy.
What is a Bohr model of oxygen?
The Bohr model for oxygen shows eight protons and neutrons in the nucleus of the atom, with eight electrons orbiting the nucleus in two energy levels….
How did Bohr prove his model?
Using Planck’s constant, Bohr obtained an accurate formula for the energy levels of the hydrogen atom. He postulated that the angular momentum of the electron is quantized–i.e., it can have only discrete values.
What is the symbol of chlorine?
Cl
Is chlorine a good disinfectant?
Chlorine as a bleach Chlorine reacts with sodium hydroxide to sodium hypochlorite (NaOCl). This is a very good disinfectant with a stable effect.
Can chlorine dioxide kill you?
Consumption of chlorine dioxide solutions, such as MMS, can cause nausea, vomiting, diarrhea, and severe dehydration. These products should not be consumed or given to someone to consume. The sale of these products as miracle cures is dangerous and has resulted in criminal convictions.
Is chlorine dioxide a carcinogen?
Cancer Assessment Under the current guidelines (U.S. EPA, 1986), chlorine dioxide is classified as Group D; not classifiable as to human carcinogenicity because of inadequate data in humans and animals.
Is chlorine dioxide safe for humans?
Chlorine dioxide is toxic and can burn or severely irritate the skin and eyes in high concentrations [30]. The Occupational Safety and Health Administration states that the highest exposure to chlorine dioxide in the air should be 0.1 ppm and 0.3 mg/m3 [31].
What did Bohr win the Nobel Prize for?
Nobel Prize in Physics
What is the Bohr model for beryllium?
The Bohr Model for Beryllium (Be) has 4 protons in the nucleus due to the atomic number of Be being 4. The Mass number is 9 which means Beryllium needs 5 neutrons in the nucleus. (Mass number = protons + neutrons, 9 = 4 + n).
Is chlorine dioxide the same as bleach?
Chlorine dioxide is mainly used as a bleach. As a disinfectant it is effective even at low concentrations, because of its unique qualities.
What is the Bohr model of chlorine?
Explanation: This is a Bohr model of a chlorine-35 atom. Some Bohr models pair six of the seven electrons in the third (valence) shell. The model does show that there are two electrons in the first shell, eight electrons in the second shell, and seven electrons in the third shell, which is correct.
Why is 3rd shell 8 or 18?
In this sense the third shell can hold 8 electrons. In this sense the third shell can hold a total of 18 electrons. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
Can you use chlorine as a disinfectant?
Chlorine is both an inexpensive and effective disinfectant if it is used properly. The chlorine referred to in this guidance document is common household bleach, free of fragrances or thickeners and possessing an EPA registration number on the label.
Is Bohr’s model correct?
This model was proposed by Niels Bohr in 1915; it is not completely correct, but it has many features that are approximately correct and it is sufficient for much of our discussion.
What’s the difference between bleach and Clorox?
They are the same thing. Clorox is just a brand name for bleach, but it’s all the same kind of bleach. Javex, Old Dutch, Clorox, any brand will do the same job.
