Balanced equation for Fe+O2 ->Fe2O3

Biology
1 answer:
NeX [460]3 years ago

<h2>Hello!</h2>

The answer is:

The balanced equation is:

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

<h2>Why?</h2>

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!

Which actions should a nurse take while caring for a preschooler whose blood lead level is found to be 25 mcg/dl? select all tha
netineya [11]
- Provide the family with lead education
- Consider treating the child with appropriate chelation therapy
- Refer the child to a clinical center specializing in lead poisoning

If the blood lead level<span> of a preschooler is found to be between 20 and 44 mcg/dL, the nurse should provide lead education to the family. The nurse should also consider treating the child with appropriate chelation therapy. The nurse may refer the child to a clinical center specializing in lead poisoning. The nurse should refer the child to social services if the child’s blood lead level is between 15 and 19 mcg/dL. The nurse should immediately provide diagnostic testing and initiate chelation therapy if the child’s blood lead level is 70 mcg/dL or greater.</span>
