This is an especially complicated valency problem, because Fe3O4 is a combination of Fe2O3 and FeO. As usual, except in peroxides and superoxides, oxygen is assigned a valency of -2. This means that the iron in Fe2O3 has a valency of +3 while the iron in FeO has a valency of +2. (Note that these two oxides of iron also occur separately from each other, as well as in Fe3O4.) Therefore, the average valency of iron in Fe3O4 is 8/3, a rare example of fractional valency made possible only by the fact that iron in this compound actually exists in two integral valence states in the same compound.

How do you find the Molar Proportions of each oxide?
To find the molar proportions of each oxide in a chemical compound, you first determine the molar masses of each element present in the compound. Then, calculate the molar ratio of each element by dividing their molar masses by the smallest molar mass. Finally, simplify the ratios to whole numbers if necessary to obtain the molar proportions.
What is the percent composition of ammonium carbonate?
Ammonium carbonate has the formula (NH4)2CO3. To calculate the percent composition, you first find the molar mass of each element and then divide the molar mass of each element in the formula by the formula mass of the compound and multiply by 100 to get the percentage.

How do you calculate the percentage composition of calcium sulfate?
You find the weights of each element in the compound and divide by their relative atomic mass to find out the moles. You find the simplest ratio of the mole values you have found and then you can find the percentages using this ratio
How do you balance a formula with fluorine uranium calcium and potassium?
To balance a chemical formula with fluorine, uranium, calcium, and potassium, you need to ensure that the number of atoms of each element is the same on both sides of the equation. Start by writing the chemical formula, then adjust the coefficients of each compound to balance the atoms of each element. It may require trial and error to find the correct coefficients that balance the formula.
How do you find valency?
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
How do find valency number?
To find the valency number of an element, look at the group number on the periodic table. For main group elements (groups 1, 2, 13-18), the valency is the same as the group number. For transition metals, the valency can vary and is usually determined by the charge of the ion formed by the element.
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
How calculate valency?
Valency is calculated in this way... 1. Find atm no of that element. 2. Write down electronic configuration. 3. Take the valence shell electron number. 4. The number of electrons to be lost are added as the valency.
How do you find valency of nitrogen in NH4 plus?
To find the valency of nitrogen in NH4+, you need to consider the overall charge of the ammonium ion, which is +1. Since there are four hydrogen atoms each with a valency of +1, the nitrogen atom must have a valency of -3 to balance out the charge of +1 on the ion. Therefore, the valency of nitrogen in NH4+ is -3.
How do you find out valency of manganese?
The valency of manganese can be determined by looking at its electron configuration. Manganese typically forms compounds in which it has a valency of +2, +3, +4, +6, or +7 depending on the specific compound it forms. This valency corresponds to the number of electrons that manganese can lose or gain to achieve a stable electron configuration.
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
