Answer: A solid-state component with three layers of semiconductors is a transistor.
Explanation:
A device with the help of which current or voltage is regulated and for electronic signals it acts as a switch or gate is known as a transistor.
A transistor has three layers of semiconductors. Each of these layers are capable of carrying current.
Thus, we can conclude that a solid-state component with three layers of semiconductors is a transistor.
Answer:
Rutherford's atomic model explained how the electrons surrounded the nucleus of protons and neutrons. His model showed how J. J. Thomson's Plum Pudding model was incorrect.
Answer:Rutherford model of an atom shows that an atom is mostly an empty space,with electrons orbiting a fixed positively charged nucleus in set.
Explanation:
The total pressure of the gaseous mixture is 1.57 atm.
The mixture of the gases consists of 3 diatomic molecules, 6 monoatomic molecules, and 5 other monoatomic molecules.
The total number of molecules in the mixture are:
The total pressure of a gas by Raoult's law is given as:
The partial pressure of the diatomic gas is 0.330 atm.
The mole fraction of the diatomic gas is given as:
The mole fraction of the diatomic gas is 0.2.
The total pressure of the gas is given as:
The total pressure of the gaseous mixture is 1.57 atm.
Learn more about the pressure of the gas, here:
Explanation:
The given data is as follows.
Number of particles of diatomic gas = 3
Number of particles of monoatomic gas = 6
Number of particles of another monoatomic gas = 5
Therefore, total number of particles or moles present will be as follows.
3 + 6 + 5 = 14
As we know that, mole fraction =
Hence, more fraction of the diatomic gas will be as follows.
mole fraction =
=
= 0.21
Now, formula to calculate partial pressure will be as follows.
Partial pressure of one species = molar fraction of that species x total pressure
Therefore,
= 1.57 atm
Thus, we can conclude that total pressure is 1.57 atm.
Answer:
Colligative properties depend on the quantity of solute and solvent and the identity of the solvent.
Explanation:
Colligative properties are defined as a set of intensive physical properties that result from the interactions between solute and solvent that form a solution. In this group of properties, we can find the freezing point depression, boiling point elevation, osmotic pressure, and vapor pressure lowering.
The mentioned properties dependon the amount of solute and solvent (concentration) and the nature of the solvent. this fact can be pictured by the freezing point depression formula:
where is the freezing point of the pure solvent, is the freezing point of the solution,is the freezing point depression constant and m is the molality
In the equation, it can be seen that the change of temperature of the solution with respect to the pure solvent depends on the molality, which is the ratio of moles of solute and mass of solvent. Moreover, the change also depends on the freezing point depression constant that is a characteristic of the solvent.
I think it is called a loess. Please correct me if I am wrong.
Answer:
A substance which burns in air and tends to produce heat and light is known as Combustible substances. Non-combustible substances are certain substances which are not combustible in the presence of air. Will not burn on being exposed to flame.
