silicon has a bandgap of 1.12 ev at 300 k. assume the fermi level is in the middle of the bandgap, determine the probability that a state at the bottom of the conduction band is occupied by an electron at 300 k.

Answers

The probability that a state at the bottom of the conduction band is occupied by an electron at 300 K is given by f(E_CB).

At 300 K, the probability that a state at the bottom of the conduction band is occupied by an electron can be calculated using the Fermi-Dirac distribution. The Fermi-Dirac distribution gives the probability that a state with energy E is occupied by an electron at temperature T, and is given by:

f(E) = 1 / (exp[(E - E_F) / (k_B T)] + 1)

Where E_F is the Fermi level, k_B is the Boltzmann constant, and T is the temperature in kelvin.

Since the Fermi level is in the middle of the bandgap, E_F = (E_CB + E_VB) / 2 = (1.12 eV / 2) = 0.56 eV.

Substituting the values into the equation, we get:

f(E_CB) = 1 / (exp[(E_CB - 0.56 eV) / (k_B * 300 K)] + 1)

Since E_CB = 1.12 eV, we get:

f(E_CB) = 1 / (exp[(1.12 eV - 0.56 eV) / (k_B * 300 K)] + 1)

= 1 / (exp[0.56 eV / (k_B * 300 K)] + 1)

Which of the following metals would be oxidized by water and oxygen in an acidic environment but not in basic environment? [answer A, B,C,D] A- Cr B- Hg C- Zn D- Cu'

Answers

The metal that would be oxidized by water and oxygen in an acidic environment but not in basic environment is Zinc (Zn). The answer is C.

Zinc reacts with water and oxygen to form zinc hydroxide and zinc oxide in a basic environment. However, in an acidic environment, zinc ions will be reduced to zinc metal by the hydrogen ions (protons) in the solution, rather than being oxidized. This is because the hydrogen ions are strong enough to reduce the zinc ions, while in a basic environment, the hydroxide ions are not strong enough to reduce the zinc ions and instead they oxidize the zinc to form zinc hydroxide.

Determining Equilibrium Concentrations

Equilibrium is a state where the rate of the forward reaction is equal to the rate of the reverse reaction. The number of molecules of each species at equilibrium depends on the reaction conditions such as temperature, pressure and the initial concentrations of reactants and products.

The reaction equation for the balance of gases at equilibrium is given by the law of mass action:

Given:  

0.80 moles of Mg = ?

Convert to "g" (units of "g" ; that is "grams" of "Mg" ).

The molar mass of "Mg"  is 24.305 g / mol    

0.80 mol  ×  (24.305 g Mg / 1 mol Mg)  = ?  g  Mg  ??

(q011) water can be used to dilute and clean up oil paint, because oil uses a natural binder: linseed oil, which is made from flax plants. T/F

Answers

False. Water cannot be used to dilute and clean up oil paint because oil and water do not mix.

The pigments in oil paint are held together by a natural binder, such as linseed oil, which is derived from flax plants. Water cannot dissolve this binder since it is not soluble in water. As a result, using water to remove oil paint might cause streaks and smudging rather than really removing the paint.

Solvents like turpentine or mineral spirits are frequently used to remove oil paint. These solvents have the ability to break down the linseed oil binder, making it simple to clean brushes, palettes, and surfaces of paint. Solvents can be combustible and emit toxic fumes, thus it is crucial to handle them carefully.

When an action potential occurs, sodium gates open, resulting in the inside of the cell becoming more negative relative to the outside.

Answers

When a voltage change crosses the threshold, the wattage na+ in the axonal barrier will open. The entry of sodium is responsible for the growing component of the nerve impulse, but the influx of ions also depolarizes nearby axonal regions. When the depolarization approaches the threshold, the nerve impulse descends the axon.

Is depolarization advantageous or detrimental?

Depolarization occurs when an electrical shift occurs in a nerve cell. The majority of cells have a negative charge in comparison to their environment. Through the brief process of depolarization, the cell's internal charge changes from negative to positive.

Does depolarization occur when sodium channels are opened?

Depolarization, a rapid increase in potential that occurs in neurons, is an all-or-nothing process that is started by the opening of sodium within the plasma membrane's ion channels.

use electron configurations orbital notation and electron dot structures to represent the formation of an ionic compound from the metal strontium and nonmetal chlorine

Answers

For metal strontium cation - E.C.- [Kr], electron dot structure -  Sr^2+, and for nonmetal chloride anion - E.C. - [Ne] 3s2 3p6, electron dot structure - Cl^-.

The formation of the ionic compound strontium chloride (SrCl2) from the metal strontium (Sr) and nonmetal chlorine (Cl) can be represented using electron configurations, orbital notation, and electron dot structures.

1. Electron Configuration:

Strontium (Sr): [Kr] 5s2

Chlorine (Cl): [Ne] 3s2 3p5

2. Orbital Notation:

Strontium (Sr): [Kr] 5s2

Chlorine (Cl): [Ne] 3s2 3p6

3. Electron Dot Structure:

Strontium (Sr): Sr

Chlorine (Cl): Cl

In the formation of an ionic compound, electrons are transferred from the metal (Sr) to the nonmetal (Cl) to form ions with a complete electron configuration. Strontium loses two electrons to form a cation with a 2+ charge, while chlorine gains one electron from each strontium atom to form an anion with a 1- charge.

The resulting electron configurations, orbital notations, and electron dot structures for the ions are as follows:

1. Electron Configuration:

Strontium cation (Sr2+): [Kr]

Chloride anion (Cl-): [Ne] 3s2 3p6

2. Orbital Notation:

Strontium cation (Sr2+): [Kr]

Chloride anion (Cl-): [Ne] 3s2 3p6

3. Electron Dot Structure:

Strontium cation (Sr2+): Sr^2+

Chloride anion (Cl-): Cl^-

These ions can then bond ionically to form the compound SrCl2. The compound is held together by the electrostatic attraction between the positively charged strontium cation and the negatively charged chloride anion.

select the correct conversion factor for each step in the following roadmap for a substance with a density of 1 g/ml. mass mass volume

Answers

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. To convert kilograms in grams and litres in millilitres, multiply with 1000 it is also known as unit conversion.

So, when converting from kilogrammes to grammes, we must first multiply by a conversion factor with kilogrammes in the denominator. As a result, kilogrammes will cancel and Graham's will be in the denominator. So the fact that there are 1000 grammes in one kilogramme is the equality that makes this true. So 1000 g and one kilogramme would be our first conversion, and kilogrammes would then cancel. To convert to millimetres, use the density conversion with one gramme in the denominator and one millimetre in the numerator because grammes will cancel.

This will give us a millilitre answer. So the first conversion we'd like to use is 1000 g over one kilogramme. So that goes in the first box, and the second box converts mass and grammes to volume. Do you prefer the one mil leader over the one g . These are the conversion factors you would need to use to complete these two steps from kg to ml.

Answers

The conversion of the given units are as follows:

98.6oF = 37°C = 310 K = 98.33°F

25.0°C = 298K = 76.73°F

131.85°C = 405 K

What is temperature ?

Temperature is a physical quantity that quantifies our feelings of hotness and coldness. A thermometer is used to measure temperature.

According to the International System of Units, the SI unit of temperature is Kelvin, which is represented by the symbol K. In the fields of science and engineering, the Kelvin scale is widely accepted or used.

However, in most parts of the world, temperature is measured using the Celsius or Fahrenheit scale.

Thus, The conversion of the given units are 98.6oF = 37°C = 310 K = 98.33°F.
