As Sn undergoes removal of 4 electrons in this reaction, it is termed as oxidation reaction.
Explanation:
Chemical reactions can be further classified as oxidation and reduction reaction. As chemical reactions consists of transfer of electrons from one element to another, it leads to formation of oxidation and reduction reaction. It is known that if an element releases electrons to attain stable state, then that element is said to undergo oxidation reaction. Similarly, if an element accepts electrons to attain stable state , then it is termed as reduction reaction.
In the present case, the reactant side contains Sn element in 2+ ionized state or oxidized state as 2 electrons are already removed in this state. And in the product side, the oxidation number increased to +4 . This means more 2 electrons are released from Sn in the product side. So as Sn undergoes removal of 4 electrons in this reaction, it is termed as oxidation reaction.
Answer:
C2H6
Explanation:
Let us first consider the molar Masses of each gas
HBr - 80.91 g/mol
NO2 - 46.0055 g/mol
C2H6 - 30.07 g/mol
We must remember that the greater the molar mass of a gas the lesser its velocity and average kinetic energy.
Looking at the gases listed, C2H6 have the highest average kinetic energy at this temperature since it has the lowest molecular mass. This reasoning is directly derived from Graham's law of diffusion in gases.
Hence C2H6 will effuse fastest when a hole is made in the container. It also possess the greatest average kinetic energy because it has the lowest molecular mass.
Answer:
Modern periodic law
Explanation:
There are many ways of stating the modern periodic law. Generally, the modern periodic law states that the properties of elements are a periodic function of their atomic numbers. That means, similar properties recur periodically when elements are arranged according to increasing atomic number.
Two scientists were largely responsible for our present day understanding of the modern periodic law, they are, Mendeleev and Moseley. Their work laid the foundation for the periodic table in its current form.
