ethane is a substance that is used when making plastic. a molecule of ethane is made of two carbon atoms and six hydrogen atoms. the carbon atoms are joined by the chemical bond. each of the hydrogen atoms is joined to one of the carbon atoms by a chemical bond. which is an accurate model of ethane?
Help ASAP!!!
Answers
Answer:
C
Explanation:
Option C is an accurate model of ethane.
Ethane is an alkane that has two carbon atoms bonded together and each atom has three hydrogen atoms that are attached to them. Ethane has single bonds and that makes it an alkane.
This model of ethane has six carbon-hydrogen bonds shown with solid lines that are protruding out. Rotation that takes place about the carbon-carbon bond actually results in the different molecular conformations of ethane.

Why do you think the elements are arranged the way that they are?
Answers
copy and paste Explanation: the reason that elements are arranged the way they are is that it makes them easier to comprehend, find, and understand.
The chemical elements are arranged this way because: they are grouped based on their atomic number (number of protons), for easy identification and predicting their ability to bond with other elements.
A periodic table can be defined as an organized tabular array of all the chemical elements typically arranged in order of increasing atomic number or number of protons (in rows).
Basically, a periodic table comprises eighteen (18) columns and seven (7) rows.
Groups, which are the families of chemical elements are represented by the vertical rows on the periodic table
On the other hand, the periods of chemical elements are represented by the horizontal columns.
Generally, the chemical elements are arranged this way because they are grouped based on their atomic number (number of protons), for easy identification and predicting their ability to bond with other elements.

A sample of phosphorus contains 1.38e24 atoms. How many moles of phosphorus is this?
2.3 grams
0.44 grams
2.3 moles
0.44 moles
Answers
Answer:
The answer is 2.3 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.38 × 10²⁴ atoms
So we have
[tex]n = \frac{1.38 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 2.29235880...[/tex]

Jason is designing a computer model that shows the structure of different molecules. His model uses spheres to represent the atoms and lines to represent bonds. His program calculates the correct angle of the bonds and allows the user to rotate the molecule to see it in three dimensions. Which change could Jason make to his program to make the model more like a real molecule?
Answers
Answer:
Explanation:
The computer model that is being described seems pretty accurate, the only change I would consider making would be a zoom in/out feature that allows the user to zoom-in in order to see the protons and electrons that make up the atoms which ultimately make up the molecule. Mainly since they are also a very important part of the molecules' structure and final composition and can be a vital piece of data, especially being able to visualize it.

An atom of tin has an atomic number of 50 and a mass number of 119. How many protons, electrons, and neutrons are found in one neutral atom of tin?
Answers
Answer:
50
Explanation:
atomic number is equivalent to it's protons, electrons and neutrons in a neutral atom
The atomic number is reminiscent of its protons, electrons, and neutrons during a neutral atom. When A particle of an atom contains 26 protons, 23 electrons, and also 56 neutrons.
Protons, Electrons, and NeutronsWhen Every atom of tin has 50 protons in its nucleus. And there'll be 50 electrons around a neutral atom of tin. the quantity of neutrons varies because there are different isotopes of tin. Tin is interesting in this it's the element with the best number of stable isotopes of all the weather within the table. it's 10 stable isotopes, and that they are tin-112 (62 neutrons), tin-114 (64 neutrons), tin-115 (65 neutrons), tin-116 (66 neutrons), tin-117, (67 neutrons), tin-118, (68 neutrons), tin-119, (69 neutrons), The tin-120 (70 neutrons), tin-122 (72 neutrons), and also tin-124 (74 neutrons). There are other isotopes of tin starting from tin-99 to tin-137, and also the neutron count in any one of them are often found by subtracting the number of tin (which is 50, or the number of protons within the nucleus), from the mass unit of the isotope. for example, if we have an interest in tin-121, it's 121 minus 50 or 71 neutrons in it.
Thus the solution is 50
