Remember this---> LEO= lose electons oxidation... and GER----> gain electrons reduction
so if you look for the one being oxidized, it is the one losing electrons. since electrons are negative, when an atom lose them, it becomes less negative, so more positive.
you can identify the oxidization when the atom becomes more positive.
so in the given reaction: <span>Ni + Sn4+ → Ni2+ + Sn2+
</span>
Ni becomes Ni +2 and Sn+4 becomes Sn+2
as you can see the Ni become Ni+2 so more positive
Ni is being oxidized
The most reasonable way to measure absolute zero would have been to extrapolate the ideal gas law.
<h3>What is Absolute zero?</h3>
This is referred to the temperature at which a thermodynamic system has the lowest form of energy.
Guillaume Amontons used gas equation to prove that absence of heat was theoretically possible which would have involved only extrapolating the ideal gas law.

The gas that is having lowest density will diffuse faster than other gases. As lesser denser will diffuse more quickly than the one which is more denser. Density is directly proportional to mass of the substance that is more mass of the substance is , more denser it will be. So here the Gas A is having lesser molecular weight than the other gases so it will diffuse more quickly than the other gases.
Gas A; MW = 14.28 g/mol
Answer:
B
Explanation:
because mass of an electron is 1/2000.
