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.

id put em on here but i cant read them to good. Hope it helps tho!
fyi if u have other worksheets u need help on if u loo up the worksheet name and answer key itll prolly pop up.
Answer : The net ionic equation will be,
Explanation :
In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The given balanced ionic equation will be,
The ionic equation in separated aqueous solution will be,
In this equation, 
are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
Answer:
the triangular model and the cubic model
