Explanation:

Electronic configuration is defined as the distribution of electrons in the energy levels around an atomic nucleus.

Atomic number helps in determining the electronic distribution of an atom.

We write electronic configuration according to Aufbau's principle in which shells are arranged in increasing energy levels.

Mercury (Hg) is a transition element and its atomic number is 80.

Electronic configuration of mercury is $[Xe]4f^{14}5d^{10}6s^{2}$ .

Would you expect soap to be a good rust remover? why or why not?.

Sergeeva-Olga [200]

The soap cannot be expected as a good rust remover, as it lacks the presence of strong acids, or petroleum products, to dissolve the rust.

<h3>What is rusting?</h3>

Rusting is the process of the formation of iron compounds with the reaction of iron with oxygen and water.

The rust can be removed with the acid and petroleum products, as their reaction dissolves the oxygen compounds.

The soap alone cannot be considered a good rust remover, as it lacks the presence of strong acids or petroleum products to dissolve the rust.

Each glucose molecule consists only of carbon, hydrogen, and oxygen atoms. If each molecule contains 53.3% oxygen and 6.7% hydro

MAVERICK [17]

53.3% + 6.7% = 60%, 100% - 60% = 40%. 40% of glucose is made of carbon. Since there are only three types of atoms in glucose, and the amount of hydrogen and oxygen is already given, this means that whatever percentage is left (40%) has to be carbon.

At 45 ∘C, Kc = 0.619 for the reaction N2O4(g)⇌2NO2(g). If 48.2 g of N2O4 is introduced into an empty 2.08 L container, what are

vodka [1.7K]

Answer:

P N₂O₄ = 3,05 atm

P NO₂ = 7,04 atm

Explanation:

48,2g of N₂O₄ are:

48,2g ₓ (1mol / 92,011g) = 0,524mol of N₂O₄ / 2,08L = 0,252M

Based on the reaction

N₂O₄(g) ⇌ 2NO₂(g) Kc = 0,619 = [NO₂]² / [N₂O₄] (1)

Concentrations in equilibrium are:

[N₂O₄] = 0,252M - X

[NO₂] = 2X

Replacing in (1):

0,619 = [2X]² / [0,252-X]

0,156 - 0,619X - 4X² = 0

Solving for X:

X = -0,289 → False answer, there is no negative concentrations

X = 0,135

Replacing:

[N₂O₄] = 0,252M - 0,135

[N₂O₄] = 0,117M

[NO₂] = 2X

[NO₂] = 2×0,135 = 0,270M

using:

P = M×R×T

Where P is pressure, M is molarity, R is gas constant (0,082atmL/molK) and T is temperature (45 + 273,15 = 318,15K). Pressure of N₂O₄ and NO₂ are:

P N₂O₄ = 0,117M×0,082atmL/molK×318,15K = 3,05atm

P NO₂ = 0,270M×0,082atmL/molK×318,15K = 7,04atm

I hope it helps!

Propiedad de los gases de aumentar su volumen al aumentar su temperatura

Nimfa-mama [501]

La propiedad que tienen los gases de aumentar su volumen al aumentar la temperatura mientras se mantiene una presión atmosférica constante, se conoce como "Dilatación". ... La ley de los gases ideales modela este fenómeno de la siguiente forma: V1/T1 =V2/T2 --------> Siempre y cuando la presión atmosférica sea constante.
