state and explain Avogadro's law
Answers
Answer:
Avogadro's Law: an Italian chemist differentiated the ultimate particle of an element that takes part in the reactions and the ultimate particle that has independent existence. The smallest particle of an element that takes part in chemical reaction is called atom. It may or may not have independent existence. The smallest particle of a substance that has independent existence is called molecule.
Avogadro argued that since smallest particle of gases that has independent existence is a molecule and not an atom hence volume of gases should be related to number of molecules and not number of atoms. He put forward Avogadro's law which states that: Equal volume of all gases under similar conditions of temperature and pressure contain equal number of molecules.
Answer:◇ Avogadro's law is the relation which states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules. The law was described by Italian chemist and physicist Amedeo Avogadro in 1811.
Avogadro's Law Equation
There are a few ways to write this gas law, which is a mathematical relation. It may be stated:
k = V/n
where k is a proportionality constant V is the volume of a gas, and n is the number of moles of a gas
Avogadro's law also means the ideal gas constant is the same value for all gases, so:
constant = p1V1/T1n1 = P2V2/T2n2
V1/n1 = V2/n2
V1/n2 = V2/n1
where p is pressure of a gas, V is volume, T is temperature, and n is number of moles
Implications of Avogadro's Law
There are a few important consequences of the law being true.
◇ The molar volume of all ideal gases at 0°C and 1 atm pressure is 22.4 liters.
◇ If pressure and temperature of a gas are constant, when the amount of gas increases, the volume increases.
◇ If pressure and temperature of a gas are constant, when the amount of gas decreases, the volume decreases.
◇ You prove Avogadro's Law every time you blow up a balloon.
