Answer: Reducing agent in the given reaction is Sn.
Explanation: Reducing agents are defined as the reagents which reduces the other substance and itself gets oxidized.
Oxidation reactions are defined as the reactions in which loss of electrons occur. the oxidation state of the substance is increased in this type of reaction.
For a given chemical reaction:
On reactant side:
Oxidation state of Hydrogen = +1
Oxidation state of oxygen = -2
Oxidation state of Nitrogen = +5
Oxidation state of Sn = 0
On product side:
Oxidation state of Hydrogen = +1
Oxidation state of oxygen = -2
Oxidation state of Nitrogen = +4
Oxidation state of Sn = +4
From above, the oxidation state of Sn is increasing. So, this element will undergo oxidation reaction and hence, is considered as a reducing agent.

Answer:
The charge carried by each ion (oxidation state of each atom)
Explanation:
If we have an ionic compound and we want to write its formula, we must first know the magnitude of charge on each ion (shown as oxidation state of the atoms involved) because the magnitude of charge on each ion is eventually crisscrossed and gives the subscript (number of atoms) for each atom in the formula.
For instance, let us write the formula of calcium bromide. Ca has a charge of +2 while Br has a charge of -1. If we exchange the charges and ignore the signs such that the crisscrossed charges form subscripts we can now write; .
The density of the wood : 1.45 g/cm³
<h3>Further explanation </h3>Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density
m = mass
v = volume
- Volume of the wood
- density
