Read the following redox reaction and determine which reactant is reduced and which is oxidized.
f2 + zn --> znf2
which is reduced & which is oxidized? !

Answer : reactant is reduced and reactant is oxidized.

Explanation :

Redox reaction : It is a type of reaction in which an oxidation and reduction reaction takes palace simultaneously.

Oxidation : The loss of electrons or increase in the oxidation number is an oxidation.

Reduction : The gain of electrons or decrease in the oxidation number is a reduction.

The given balanced redox reaction is,

The oxidation number of = 0

The oxidation number of = 0

The oxidation number of Zn in

x + 2(-1) = 0

x = +2

The oxidation number of in = -1

That means is reduced due to decrease in the oxidation number from 0 to (-1) and 'Zn' is oxidized  due to increase in the oxidation number from 0 to (+2).

Therefore, reactant is reduced and reactant is oxidized.

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
