How do you balance Fe H2O---Fe3O4 H2?
To balance the equation Fe + H2O → Fe3O4 + H2, you need to ensure the number of atoms of each element are equal on both sides. Start by balancing the iron atoms, then balance the oxygen atoms, and finally balance the hydrogen atoms. The balanced equation is 3Fe + 4H2O → Fe3O4 + 4H2.
How many moles of iron can be recovered from 100.0 kg of Fe3O4?
Well first things first you have to balance the equation Fe3O4-->3Fe+2O2 Then because your given mass is in kg you have to convert it to grams 100.0kgx1,000kg/(over)1g=100,000g or 1.0x105 Next because you have mass of Fe3O4 you need to get the molar mass. (3)55.85gFe+(4)16.00gO=231.55gFe3O4 Now convert grams to moles for your final answer 1.0x105gFe3O4x1mol/(over)231.55g(mm)x3molFe/(over)1mol Fe=1295.6 mol Fe you can recover 1295.6moles of Fe from Fe3O4 If you follow the rule of Significant Figures, 100.0kg has 4 significant figures (digits) so your answer needs to have 4 digits 1295.6=1296 you can recover 1296 moles of Fe from Fe3O4
When the equation Fe3O4 plus Al - Al2O3 plus Fe is correctly balanced what is the coefficient of Fe?
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
What is the oxidation number of Fe in FE203?
Fe3O4 is a complex oxide (a crystaline solid containing more than one cation). In this case Fe exists as both the 2+ and 3+ cation. There are two 3+ ions and one 2+ ion for every four O2- ions. The charge balance is: 2x3+ + 2+ + 4x2- = 0
How many atoms does Fe3O4 have?
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
How do you balance Fe H2O---Fe3O4 H2?
To balance the equation Fe + H2O → Fe3O4 + H2, you need to ensure the number of atoms of each element are equal on both sides. Start by balancing the iron atoms, then balance the oxygen atoms, and finally balance the hydrogen atoms. The balanced equation is 3Fe + 4H2O → Fe3O4 + 4H2.
How do you balance the folowing equation Fe H20 --Fe3O4 H2?
Fe3O4 is the mineral magnetite, with aproper chemical name of Fe(II, III) oxide. it exhibits ferrimagnetism. It has iron atoms as FeII and FeIII. An old way of writing it was FeO.Fe2O3 The balanced equation for production from the elements is :- 3Fe + 2O2 -> Fe3O4 Commercially it is made by for example redung Fe2O3 with CO 3Fe2O3 + CO = 2Fe3O4 +CO2

What is another name for a synthesis reaction that involves oxygen?
A combustion reaction. It's not a combustion reaction, it's a COMBINATION reaction Example 3 Fe + 2 O2 ----------> Fe3O4
When the equation Fe3O4 plus Al - Al2O3 plus Fe is correctly balanced what is the coefficient of Fe?
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
What is the chemical equation for iron burning in oxygen?
4 Fe+ 3O2 + 6 H2O 4 Fe(OH)3 2 Fe2O3 + (x)H2OThis means that water doesn't actually react, but is necessary to perform the reaction and comes out as it is.
What is the oxidation number of Fe in FE203?
Fe3O4 is a complex oxide (a crystaline solid containing more than one cation). In this case Fe exists as both the 2+ and 3+ cation. There are two 3+ ions and one 2+ ion for every four O2- ions. The charge balance is: 2x3+ + 2+ + 4x2- = 0
How many atoms does Fe3O4 have?
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
What coefficients balance the equation Fe O2 Fe2O3?
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
Calculate the oxidation number of Fe in Fe3O4?
In Fe3O4, the oxidation number of Fe is +8/3. This can be found by setting up an equation where the total sum of the oxidation numbers in the compound equals the overall charge. In this case, Fe3O4 has a neutral charge, so the total sum of oxidation numbers is zero.
How many Fe atoms are in 0.25 moles of Fe?
To determine the number of moles of Fe that can be made from 25 moles of Fe2O3, you need to write the balanced chemical equation for producing O2 from Fe2O3. 2Fe2O3 = 4Fe + 3O2, which means that 2 moles of Fe2O3 will produce 4 moles of Fe and 3 moles of O2 . Set up a proportion. 3 moles of O2 ÷ 2 moles of Fe2O3 = x moles of O2 ÷ 25 moles of Fe2O3 Cross multiply and divide. 3 moles of O2 * 25 moles of Fe2O3 ÷ 2 moles of Fe2O3 = 37.5 moles of O2 produced.
How many moles of fe2o3 are made from 6 moles of o2?
Fe ions =,Fe 2+andFe 3+Oxygen ions =,O 2-So, as you should see, Fe3O4, is an invalid species as the charge on the first iron ion would be 3 * 2+ = 6 +, and the charge on the second iron ion would be 3 * 3+ = 9+. This can not equal 4 * 2- = 8 -.
