What happens to iron when iron oxide becomes elemental iron?

Chemistry

The appropriate response is Reduction. It is a chemical reaction that includes the picking up of electrons. It alludes to the side that acknowledges electrons. At the point when iron responds with oxygen, it frames a concoction called rust. In that case, the iron is oxidized and the oxygen is lessened.

Answer:

Iron gets reduced from a +3 oxidation state to 0

Explanation:

The decomposition of iron oxide to elemental can be represented by the following equation:

2Fe_{2} O_{3} (s)------ 4Fe(s) + 3O_{2} (g)

In iron oxide (Fe2O3), the oxidation state of iron is +3 while that of oxygen is -2. Therefore, the above reaction is a redox (reduction oxidation reaction).

Here, iron in iron oxide gains 3 electrons and gets reduced from Fe3+ to Fe(0). Whereas, the oxygen loses 2 electrons and gets reduced from O2- to O(0).

The half reactions can be represented as:

Reduction:

Fe^{3+} + 3e- ------- Fe

Oxidation:

O^{2-} -------O + 2e-

A box of jello has a mass of 250 g. How many boxes must be bought to have 1 Kg of jello? *
zhuklara [117]

Answer:

Number of boxes = 4

Explanation:

Given:

Mass of one box of jello = 250 grams

Total quantity want to purchase = 1 kg = 1 × 1,000 gram = 1,000 grams

Find:

Number of boxes in 1,000 grams = ?

Computation:

Number of boxes = Total quantity want to purchase / Mass of one box of jello

Number of boxes = 1,000 / 250

Number of boxes = 4

Therefore, 4 boxes of jello must be purchase to get 1 kg of Jello.

In a redox reaction, reduction is defined by the:
jonny [76]

Answer:

C. Gain in electron(s) resulting in a decrease of oxidation number.

Explanation:

Redox reactions are reactions involving transfer of of electron between two species (reduction specie) and (oxidation species) and change resulting in change in oxidation number.

Reduction in terms of redox reaction is the specie that accepts electron(s) and gets "reduced" since its oxidation state has been reduced.

For example

Cl + e- → Cl⁻

The above reaction is an example of reduction reaction taking place in a redox reaction. We can see that Chlorine oxidation state was changed from (0) to (-1) state.
