The maximum safe operating temperature for this reaction is equal to 895°C.
Given the following data:
Width of cylinder = 22 cm.Height, h = 26.4 cm.Maximum safe pressure = 6.30mpa.Mass = 0.537 kg.Scientific data:
Ideal gas constant, R = 8.314 L-kPa/Kmol.Molar mass of of dinitrogen monoxide ([tex]N_2F_2[/tex]) gas = 66 g/mol.Radius, r = [tex]\frac{width}{2} =\frac{22}{2} =11\;cm[/tex]
How to calculate the maximum safe operating temperature.First of all, we would determine the volume of the stainless-steel cylinder by using this formula:
[tex]V=\pi r^2 h\\\\V = 3.142 \times 11^2 \times 26.4\\\\[/tex]
Volume, V = 10,036.81 [tex]cm^3[/tex].
In liters, we have:
Volume, V = 10.04 Liters.
Next, we would determine the number of moles of dinitrogen monoxide ([tex]N_2F_2[/tex]) gas:
[tex]Number \;of \;moles = \frac {mass}{molar\;mass}\\\\Number \;of \;moles = \frac {537}{66}[/tex]
Number of moles = 8.136 moles.
Now, we can solve for the maximum safe operating temperature by applying the ideal gas equation:
[tex]PV=nRT\\\\T=\frac{PV}{nR} \\\\T=\frac{6.30 \times 10^3 \times 10.04}{8.136 \times 8.314}\\\\T=\frac{60541.2}{67.6427}[/tex]
T = 895.02 ≈ 895°C.

Explanation:
The ion with 86 electrons, 142 neutrons, and a 4+ charge
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
The ion had 4+ charge when it had 86 electrons, so it should have no charge on it if there are 4 more electrons and the atom will be neutral.
And since we know that number of electrons in a neutral atom is equal to Atomic Number of that atom.
So, at neutral phase, it had 86 + 4 = 90 electrons
hence, our required atom is : Thorium
And it's ion will be ~[tex]\sf Th^{4+} [/tex]

The density of chlorine gas at 0.970 atm and 29.8 °C is ________ g/L.
Answer:
d=3.95 g/l
Explanation:
1) Ideal gas equation:
pV = nRT
2) Transform the equation to compute density, d = m / V
n = mass in grams / molar mass = m / MM
pV = (m/MM) RT
=> pV = mRT/MM
=> m/V = pMM / (RT)
d = pMM / (RT)
p = 1.21 atm
MM = 83.80 g/mol (this is the atomic mass of krypton element)
T = 50 + 273.15 K = 323.15K
3) Compute:
d = (1.25 atm * 83.80 g/mol) / (0.0821 atm*liter /K*mol * 323.15K)
How would Bohr model show the protons in a carbon atom
Answer:
The Bohr model show the protons in a carbon atom using the model; "Electrons move in fixed orbits around a nucleus of protons and neutrons."
According to Bohr's model of the atoms, the Rutherford model is basically correct. This implies that Bohr model accepts the idea of a nucleus containing nucleons(protons and neutrons).
In addition, the model also postulates that electrons are found in fixed orbits. These fixed orbits are called energy levels or shells.

What components make up transitions?Transition elements are substances with partially filled d orbitals, sometimes referred to as transition metals. According to IUPAC, a transition element is an element with a partially filled d subshell or one with the capacity to create stable cations that has an unfilled d orbital.
Why are transitional elements called that?As a result of their transitional behavior between s-block or p-block elements, the d-block elements are referred to as transition elements. Their characteristics are intermediate between those of the covalently-bonded, highly reactive s-block metallic elements and those of the p-block elements.

The more solute is broken down in solution the less conductive the solutions is. True or False
Answer:
False.
Explanation:
If the answer to this question was true, then that would mean that the more the solute is broken down, the less it'll dissolve... and everyone know that this doesn't make sense. I hope I explained this is an easy manner so you could understand! Good luck! :)
The more solute is broken down in solution the more conductive the solutions is and the statement is False.
What effects the conductive nature of a solution?
Conductivity depends upon solvation of ions present in solution. Greater the solvation of ions, lesser is the conductivity.
Solvation is the process in which molecules of a solvent attract the particles of a solute.
The main forces in solvation are ion-dipole and hydrogen bonding attractions.
The more concentrated a solution is, the greater the conductivity measured (if the solute is a conductor in solution). This is because the higher the concentration of the solute, the more ions will be available to carry electric charge.
Therefore, the more solute is broken down in solution the more conductive the solutions is and the statement is False.
