Balanced equation for Fe+O2 ->Fe2O3

NeX [460]

<h2>Hello!</h2>

The answer is:

The balanced equation is:

$4Fe+3O_2=2Fe_{2}O_{3}$

Finding a balanced equation of a reaction means making equal the number of atoms for both reactants and products sides, according to the conservation mass law, the mass is always conserved, so, we need to make both quantities of atoms/molecules match.

So, we are given the following reaction:

$Fe+O_2=Fe_{2}O_{3}$

For the reactants, we have 1 molecule of Fe and 2 of O

For the products, we have 2 molecules of Fe and 3 of O

So, balancing the Oxygen, we have:

$Fe+3*O_2=Fe_{2}O_{3}$

$Fe+3O_2=Fe_{2}O_{3}$

Now, there are 6 atoms of oxygen in the reactant, let's multiply the product by 2 in order to make both sides match, so:

$Fe+3O_2=2*(Fe_{2}O_{3})$

$Fe+3O_2=2(Fe_{2}O_{3})$

Now, we can see that there are 6 atoms of Oxygen in both sides, but there are 4 atoms of Fe in the products and just 1 atom in the reactants, so, we need to multiply the Fe by 4.

So, balancing the Iron (Fe) we have:

$4*Fe+3O_2=2(Fe_{2}O_{3})$

$4Fe+3O_2=2Fe_{2}O_{3}$

Hence, we can see that we now have the same number of atoms on both sides, we have:

$Fe_{reactants}=4\\O_{reactants}=6\\Fe_{products}=4\\O_{products}=6$

Therefore, the equation is balanced.

$4Fe+3O_2=2Fe_{2}O_{3}$

Have a nice day!

Difference between palisade cell and fungi hypha cell

dlinn [17]

Palisade cells are a specific type of plant cell. They have chloroplasts and do most of the photosynthesis in the leaf. Because palisade cells are plant cells, they also have the differences always found between plant and animal cells. They have a cell wall; animal cells have only a cell membrane.

Indicate, as true or false, whether each of the following statements about species is a component of the biological species conc

adell [148]

Their reproductive isolation from each other is complete: False

They are unable to produce hybrid offspring upon interbreeding: True

They shared a common ancestor recently in evolutionary time: False

Explanation:

A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.

This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
