Answer:
Find the limiting reactant.
Explanation:
Using the ratio in the chemical formula, find the limiting reactant.
[tex]0.164mol Mn*\frac{2molMnO3}{2molMn} = 0.164molMnO3[/tex]
[tex]0.232molO2*\frac{2molMnO3}{3molO2} = 1.55molMnO3[/tex]
The second equation results in less mol of MnO₃, therefore it is the limiting reactant and changing the moles of O₂ to moles of MnO₃ which will give the theoretical yield which is 1.55 mol MnO₃.

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.

An unknown element has 2 naturally occurring isotopes. The first isotope has an atomic mass of 84.9117 and the second isotope has an atomic mass of 86.909. Their abundances are 72.2% and 27.8% respectively.
Answer Choices: 85.56 86.44 85.21 86.00
Answers
Answer:The other isotope, 65Cu, has an abundance of 30.91%. Calculate the average atomic mass of copper. 63Cu 0.6909 x 63= 43.5267 65Cu 0.3091 x 65= +20.0915
Explanation:Nov 17, 2015 — The average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes. Now, weighted average ... avg. atomic mass=∑i(isotopei×abundancei). The more ... of the element. In your case, you know that rubidium has two stable isotopes.
Explanation:
To find the average atomic mass of the element we must take a weighted average. Using the formula [tex]am = (m_{1} * abundance)[/tex] . Plug and chug gives us
[tex]am = (84.9117 * 0.722) + (86.909 * 0.278) = approx. 85.56g/mol[/tex]

A mechanical pencil has the density of 3 grams per cubic centimeter. The
volume of the pencil is 15.8 cubic centimeters. What is the mass of the
pencil?
Answers
Answer:
The answer is 47.4 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume = 15.8 cm³
density = 3 g/cm³
We have
mass = 3 × 15.8
We have the final answer as
47.4 gHope this helps you

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

An orbital that could never exist according to the quantum description of the atom is
Answers
Answer:
d. 3f
Explanation:
An orbital in chemistry is defined as the wave function that defines the position of electrons in an atom.
There are four types of orbitals that include s, p, d, and f. On the basis of the quantum description, 3f orbital does not exist because in the third energy level only three sublevels are present that are s, p, and d that can hold a maximum of 18 electrons.
Hence, the correct answer is "d.3f".
For the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.
Quantum mechanics helps in the determination of the electron address. The electron address has been given by the 4 quantum numbers namely,
Principal quantum numberAzimuthal quantum numberMagnetic quantum numberSpin quantum numberThe principal quantum number gives the information to the orbital, and the azimuthal quantum number gives the information of the subshell.
The orbitals have been formed by the mixing of the bonding and anti-bonding orbital. The mixing of the 3 orbital has resulted in the 3 suborbital namely s, p, and d.
Thus for the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.

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.
